Convert C# to VB.NET


There are various ways to converting CSharp to Visual Basic .Net . I explain about to to convert C# to VB.NET

This sample shows how to programmatic convert C# code to VB.NET and vice-versa. I am using the sharpdevelop's ICSharpCode.NRefactory namespaces here to convert code.

You can download the assemblies from http://www.icsharpcode.net/OpenSource/SD/Download

The first parameter of the method is the actual code that need to be converted. Second parameter specifies whether to convert from C# to VB.NET or vice versa. Pass 'true' to convert from C# to VB.NET. Pass 'false' to convert from VB.NET to C#.


Private Function ConvertCodeSnippet(ByVal codeToConvert as string, ByVal csharpToVb As Boolean) as string
Dim input As New StringReader(codeToConvert)
Dim parser As IParser

parser = ParserFactory.CreateParser(IIf(csharpToVb, SupportedLanguage.CSharp, SupportedLanguage.VBNet), input)

parser.Parse()

If (parser.Errors.count > 0) Then
return parser.Errors.ErrorOutput
End If

Dim cu As CompilationUnit, output As IOutputASTVisitor
cu = parser.CompilationUnit

output = IIf(csharpToVb, CType(New VBNetOutputVisitor(), IOutputASTVisitor), CType(New CSharpOutputVisitor(), IOutputASTVisitor))

cu.AcceptVisitor(output, DBNull.Value)
return output.Text
End Function

Hi




private string ConvertCodeSnippet(string codeToConvert, bool csharpToVb)
{
StringReader input = new StringReader(codeToConvert);
IParser parser;

parser = ParserFactory.CreateParser(IIf(csharpToVb, SupportedLanguage.CSharp, SupportedLanguage.VBNet), input);

parser.Parse();

if ((parser.Errors.count > 0)) {
return parser.Errors.ErrorOutput;
}

CompilationUnit cu;
IOutputASTVisitor output;
cu = parser.CompilationUnit;

output = IIf(csharpToVb, (IOutputASTVisitor)new VBNetOutputVisitor(), (IOutputASTVisitor)new CSharpOutputVisitor());

cu.AcceptVisitor(output, DBNull.Value);
return output.Text;
}
