Convert vb.net (2003) to c# (2005)

Hello Experts,
Can anyone help me conver the following vb.net 2003 code to c# 2005 ?
Thanks

   Public shared Function MD5HashHex(ByVal InString As String) as String
                        For SrcIdx = 0 To InString.Length() - 1
                            Data(DstIdx) = AscW(InString.Substring(SrcIdx, 1)) And &H00FF
                            DstIdx += 1

                            Data(DstIdx) = (AscW(InString.Substring(SrcIdx, 1)) And &HFF00) >> 8
                            DstIdx += 1
                        Next

                        Dim Result As Byte() = md5.ComputeHash(Data)
                        Dim SResult as String = ""

                        For DstIdx=0 to Result.Length() - 1
                            SResult = Microsoft.VisualBasic.Format(Result(DstIdx), "X").PadLeft(2, "0") & SResult
                        Next

                        Return SResult
                    End Function

 return SResult;
}

For future reference, there is a little online tool for converting c# to vb.net and viceversa:

samtran0331Commented:
there is nothing wrong with the conversion itself..it's not a fully "encapsulated" function and is using variables I assumed are declared publicly somewhere else on the page or class file...
in both versions, there are a bunch of external variables and references to the variables that are causing the errors...
SrcIdx,DstIdx,Data and md5

try this:

using System.Security.Cryptography;

public static string MD5HashHex(string InString)
{
    byte[] bytes = Encoding.UTF8.GetBytes(InString);
    // or Encoding.ASCII.GetBytes(InString);

    HashAlgorithm hash = new MD5CryptoServiceProvider();
    byte[] hashBytes = hash.ComputeHash( bytes );

    StringBuilder sb=new StringBuilder();
    foreach(byte b in hashBytes)
         sb.Append( b.ToString("X2") );
    return sb.ToString();
}


Or you can simply let it in vb.net, compiling it as a DLL assembly which you use when compiling your C# project.
