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
