每次要从VB.NET转换到C＃或返回时，问这样的问题都不好。它可以使用一些离线工具自动完成;特别注意由精彩的开源工具ILSpy提供的最全面的离线方法。请参阅我过去的答案以获取更多详细信息：

你不能指望100％转换，你必须自己做一些手动更改。可能你可以使用其他转换器进行更接近的转换。

Hi Guys.

I've tried to convert a C# code to vb.net. I tried the C# code and it was successful with an output on a console, i have tried to copy it and convert it into vb.net but the output should be on a textbox but there is no output and there is no error either. Can you please help me with this.

C# code:

using System;
using MT4API;

class Program
{
  static void Main(string[] args)
  {
    string symbol = "EURUSD";
    MT4DDE dde = new MT4DDE("");
    dde.OnQuote += new EventHandler<QuoteEventArgs>(MT_OnQuote);
    dde.Connect();
    dde.Subscribe(symbol);
    Console.WriteLine("Press any key...");
    Console.ReadKey();
    dde.Unubscribe(symbol);
  }


  private static void MT_OnQuote(object sender, QuoteEventArgs args)
  {
    Console.WriteLine(args.Symbol + " " + args.Bid + " " + args.Ask);
  }

}

VB.Net Code:

Imports MT4API

Public Class Form1
    Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        Try
            Dim symbol As String = "EURUSD"
            Dim dde As New MT4DDE("cms")
            AddHandler dde.OnQuote, AddressOf MT_OnQuote
            dde.Connect()
            dde.Subscribe(symbol)
            TextBox1.Text = "Press any key" + vbCrLf
            dde.Unubscribe(symbol)
        Catch ex As Exception
            TextBox1.Text = TextBox1.Text + ex.Message
        End Try
        
    End Sub

    Private Sub MT_OnQuote(ByVal sender As Object, ByVal args As QuoteEventArgs)
        TextBox1.Text = TextBox1.Text + args.Symbol + vbTab + args.Bid + vbTab + args.Ask + vbCrLf
    End Sub

End Class

Thank you very much.

It's not good to ask such question each time you want to translate from VB.NET to C# or back. It can be done automatically, using some on-line of off-line tools; pay special attention for the most comprehensive off-line method provided by the wonderful open-source tool ILSpy.

You can't expect 100% conversion, you have to do some manual changes yourself. Possibly you could get some more closer conversion using other convertors.
