Thanks darwen. but i am getting some build problem when i try to call the methods defined in the *.cs file.

i have opened *.cs file through 'File | New... | C# | C# Class file'

//myClass.cs file

using System;

/// <summary>
/// Summary description for Class1
/// </summary>
///
namespace mynameSpace
{
public class myClass
{
public myClass()
{
//
// TODO: Add constructor logic here
//
}
public int clConnect()
{

return 1;
}

public int clQuit()
{
return 1;
}
}
}


// cpp file has this

...
using namespace mynameSpace ;

int clConnect()
{
return myClass::clConnect();
}

int clQuit()
{
return myClass::clQuit();
}

//errors i am getting at build time of the DLL

1>.\export_functions.cpp(19) : error C2871: 'mynameSpace' : a namespace with this name does not exist
1>.\export_functions.cpp(27) : error C2653: 'myClass' : is not a class or namespace name
