Metroit

Several classes to support logic, and WinForms extension control.
We will do some help in an environment where development using WinForms is done.
It eliminates troublesome implementation by pulling out what is likely to be good.
It may be a little cleared of the problem if there are problems that you are having troubles, or if you have restrictions on using WPF or EntityFramework.

Metroit

It is a library that contains basic classes.

Dictionary with upper limit

We will use a Dictionary that intentionally needs an upper limit.

var dic = new Metroit.Collections.Generic.LimitedDictionary<string, string>(3);
dic.Add("key1", "value1");
dic.Add("key2", "value2");
dic.Add("key3", "value3");
if (!dic.CanAdd()) {
    dic.Add("key4", "value4");  // ArgumentException
}

Extension of string class

using Metroit.Extensions;

// Insert delimiters on judgment of capital letters.
var value = "TestTestTest";
Console.WriteLine(value.InsertSeparator("_", SeparateJudgeType.UpperChar));  // Test_Test_Test

var value = "(aaa(bbb(ccc)ddd)eee)";
value = value.GetEnclosedText(); // aaa(bbb(ccc)ddd)eee
value = value.GetEnclosedText(); // bbb(ccc)ddd
value = value.GetEnclosedText(); // ccc

Rounding calculation

// The decimal second place leaves it off in 4 or more.
var value = 1.24;
value = Metroit.MetMath.Round(1, 4, MidpointRounding.AwayFromZero); // 1.3

// I leave off the decimal third place
var value = 1.123;
value = Metroit.MetMath.Ceiling(1, 2); // 1.13

// I cut off the decimal third place
var value = 1.123;
value = Metroit.MetMath.Floor(1, 2); // 1.12

// I cut off the decimal third place
var value = 1.123;
value = Metroit.MetMath.Truncate(1, 2); // 1.12

Some kind of conversion

With ConverterBase class, I can make a class converting something.

using Metroit.IO;

class TestConverter : ConverterBase
{
    public TestConverter() :base()
    {
        Prepare += TestConverter_Prepare;
        ConvertCompleted += TestConverter_ConvertCompleted;
    }
    protected void DoConvert(IConverterParameter parameter)
    {
        // I convert something
    }
    private void TestConverter_Prepare(IConvertParameter parameter, CancelEventArgs e)
    {
        // Preparations processing
        // e.Cancel = true is cancel conversion
    }
    private void TestConverter_ConvertCompleted(IConvertParameter parameter, ConvertCompleteEventArgs e)
    {
        // Completed processing
        switch (e.Result) {
            case ConvertResultType.Succeed:
                break;
            case ConvertResultType.Failed:
                Console.WriteLine(e.Error.ToString());
                break;
            case ConvertResultType.Cancelled:
                break;
        }
    }
}

class Test
{
    var converter = new TestConverter();
    var result = converter.Convert();
    if (result == ConvertResultType.Cancelled)
    {
        return;
    }
    // var t = converter.ConvertAsync(); // 4.5 only
}

Conversion of the file

With FileConverterBase class, I can make a class converting a file.

using Metroit.IO;

class TestFileConverter : FileConverterBase
{
    public TestFileConverter() : base() { }

    protected override void ConvertFile(FileConvertParameter parameter)
        // ファイルの変換処理など
        File.Copy(parameter.SourceConvertFileName, parameter.DestConvertFileName);
    }
}

class Test
{
    public void Hoge()
    {
        var converter = new TestFileConverter()
        {
            Parameter = new FileConvertParameter() {
                SourceFileName = "C:\test.txt",
                DestFileName = "D:\test.dat",
                UseDestTemporary = true,
                Overwrite = true
            },
            Prepare = (p, e) => {
                e.Cancel = false;
                Console.WriteLine("Convert prepare process.");
            },
            Complete(p, e) => {
                Console.WriteLine(e.Result.ToString() + e.Error?.Message);
                Console.WriteLine("Convert complete process.");
            }
        };
        var result = converter.Convert();
        if (result == ConvertResultType.Cancelled)
        {
            return;
        }
    }
}

Using IFileConverterFactory, IFileConverterFactoryMetadata, I can realize simple MEF.

using Metroit.IO;

[Export(typeof(IFileTypeConverterFactory))]
[ExportMetadata("ConverterName", "XlsToPdf")]
[ExportMetadata("FromType", "xls")]
[ExportMetadata("ToType", "pdf")]
public class TestConverterFactory : IFileTypeConverterFactory
{
    public IO.FileTypeConverter Create()
    {
        return new TestConverter();
    }
}

Converting Enums

Converts to a predefined enum reliably.

public enum ProcessType
{
    Succeed,
    Failed
}

var result = MetEnum<ProcessType>.Parse("1"); // ProcessType.Failed
var result = MetEnum<ProcessType>.Parse("Failed"); // ProcessType.Failed
var result = MetEnum<ProcessType>.Parse(2); // System.ArgumentException

Get the length of a string

This is mainly for Japanese and calculates the length by treating one full-width character as two characters.
This is effective when you want to limit the number of input characters based on the number of half-width characters.

using Metroit.Extensions;

var text = "123あいう";
var length = text.GetTextCount(true); // 9

Check if it is a full-width character

This mainly targets Japanese and checks whether a specific character is a full-width character.

using Metroit.Extensions;

var text = "あ";
var isFullWidth = text.IsFullWidth(true); // true

Converts ASCII strings between half-width and full-width characters

It mainly targets Japanese and converts ASCII characters between half-width and full-width.

using Metroit.Text;

var halfText = @"aA=\";
var result = AsciiConverter.ToFullWidth(halfText);  // ａＡ＝＼
var result = AsciiConverter.ToFullWidth(halfText, true);  // ａＡ＝￥

var fullText = "ａＡ＝＼￥";
var result = AsciiConverter.ToHalfWidth(fullText);  // aA=\￥
var result = AsciiConverter.ToHalfWidth(fullText, true);  // aA=\\

Converts kana strings between half-width and full-width

It mainly targets Japanese and converts kana characters between half-width and full-width.

using Metroit.Text;

var halfText = "ｶﾅｶﾞﾊﾞﾊﾟﾟ";
var result = KatakanaConverter.ToFullWidth(halfText);  // カナガバパ゜

var fullText = "カナガバパ゜";
var result = KatakanaConverter.ToHalfWidth(fullText);  // ｶﾅｶﾞﾊﾞﾊﾟﾟ

Converting strings

It mainly targets Japanese and converts ASCII characters in strings and kana characters between half-width and full-width.

using Metroit.Text;

var halfText = @"aA=\ｶﾅｶﾞﾊﾞﾊﾟﾟ";
var result = TextConverter.ToFullWidth(halfText, true, true, true);  // ａＡ＝￥カナガバパ゜

var fullText = "ａＡ＝＼￥カナガバパ゜";
var result = TextConverter.ToHalfWidth(fullText, true, true, true);  // aA=\\ｶﾅｶﾞﾊﾞﾊﾟﾟ

Metroit.Data

A library that contains functions to aid database operation.

Connect to the database

You do not have to memorize the immutable name of the provider.
You can set connection information by Dictionary.

using Metroit.Data.Common;
using Metroit.Data.Extensions;

var pf = MetDbProviderFactories.GetFactory(DatabaseType.Oracle);
using (var conn = pf.CreateConnection()) {
    conn.SetConnectionString(pf, new Dictionary<string, string>()
        {
            {"Data Source", "192.168.11.102/ORACLE" },
            {"User ID", "TEST" },
            {"Password","test" }
        });
    conn.Open();
}

MetDbProviderFactories.GetFactory() is not available in netstandard20.

Execute the query

DbConnection.CreateQueryCommand() will automatically enforce BindByName().

// conn : DbConnection
var query = "SELECT * FROM TBL WHERE COLUMN1 = :COLUMN1 AND COLUMN2 = :COLUMN2";
var comm = conn.CreateQueryCommand(query);
// pf : ProviderFactiry
comm.Parameters.Add(pf.CreateParameter("COLUMN1", "value"));
comm.Parameters.Add(pf.CreateParameter("COLUMN2", "value"));
var dt = new DataTable();
comm.Fill(pf, dt);

Execute a query using a transaction

DbConnection.CreateQueryCommand() will automatically enforce BindByName().
After creating DbTransaction, you do not need to manipulate DbConnection.

using Metroit.Data.Extensions;

// conn : DbConnection
using (var trans = conn.BeginTransaction())
{
    var query = "SELECT * FROM TBL WHERE COLUMN1 = :COLUMN1 AND COLUMN2 = :COLUMN2";
    var comm = trans.CreateQueryCommand(query);
    // pf : ProviderFactiry
    comm.Parameters.Add(pf.CreateParameter("COLUMN1", "value"));
    comm.Parameters.Add(pf.CreateParameter("COLUMN2", "value"));
    var dt = new DataTable();
    var da = comm.Fill(pf, dt, true, true);
    da.Update(dt);
    trans.Commit();
}

Retrieve execution result of procedure

using Metroit.Data.Extensions;

// conn : DbConnection
var query = "ProcedureSample";
var comm = conn.CreateProcedureCommand(query);
// pf : ProviderFactiry
var parameter = pf.CreateParameter("COLUMN1", "value");
parameter.Direction = ParameterDirection.ReturnValue;
comm.Parameters.Add(pf);
comm.ExecuteNonQuery();
var result = comm.GetProcedureResult()
Console.WriteLine(result.ReturnValue.ToString());

Manipulate acquired data with objects

Avoid handling DataTable raw.

using Metroit.Data.Extensions;

class Tbl1
{
    public string Column1 { get; set; }

    // When property name != Column name, use ColumnAttribute
    [Column("COLUMN2")]
    public string ColumnPrpoerty2 { get; set; }
}

var dt = new DataTable();
comm.Fill(pf, dt);

foreach(var row in dt.AsEnumerableEntity<Tbl1>())
{
    Console.WriteLine(row.Column1);
    Console.WriteLine(row.ColumnPrpoerty2);
}

// When done line by line
var row = dt[0].ToEntity<Tbl1>();
Console.WriteLine(row.Column1);

Create a query string

It helps to generate a query string a little.

using Metroit.Data;

var builder = new QueryBuilder("SELECT *, /* REP */");
builder.AddQueries(new List<string>() { "FROM TBL "});
builder.ReplaceQueries(new List<string, string>() { "REP", "COLUMN1" });
var query = builder.Build(); // SELECT *, COLUMN1 FROM TBL

Perform query parameter optimization

It is optimized to find the prefix or symbol of the parameter specified in the query.
The prefix recognizes ":", "@", and the symbol "?".

using Metroit.Data;

var query = "SELECT * FROM TBL WHERE COLUMN1 = @COLUMN1";
var op = new QueryParameterOptimizer();
query = op.GetOptimizedText(query, QueryBindVariableType.ColonWithParam); // SELECT * FROM TBL WHERE COLUMN1 = :COLUMN1

---

Metroit.Windows.Forms

It is a library that helps to create WinForms application.

Since we are using Microsoft.Web.WebView2, you can suppress the warning by writing the following in the project file according to your project.

  <Target Name="RemoveUnnecessaryWebView2References" AfterTargets="ResolvePackageDependenciesForBuild">
    <ItemGroup>
      <ReferenceToBeRemoved Include="@(Reference)" Condition="'%(Reference.FileName)' == 'Microsoft.Web.WebView2.WinForms' And '$(UseWindowsForms)' != 'true'" />
      <ReferenceToBeRemoved Include="@(Reference)" Condition="'%(Reference.FileName)' == 'Microsoft.Web.WebView2.Wpf' And '$(UseWpf)' != 'true'" />
      <Reference Remove="@(ReferenceToBeRemoved)" />
    </ItemGroup>
  </Target>
