How to use "typedef CString" in .net?

[Gary]

Hi, there,

I am going to use a command line parser class, which works well in VC6.0, in
VC++7.1. However error message such as "C2059: syntax error :')'", and
"C2061: syntax error : identifier 'CCmdLineParser _String'", and "C2061:
syntax error : identifier 'LPCTSTR'" shows in compiling. What is the
problem? Following is the header of the class:

#if _MSC_VER > 1000
#pragma once
#endif // _MSC_VER > 1000
typedef CString CCmdLineParser_ String;
#include <map>
using std::map;

class CCmdLineParser {
public:
class CValsMap : public map<CCmdLinePar ser_String, CCmdLineParser_ String> {};
typedef CValsMap::const _iterator POSITION;
public:
CCmdLineParser( LPCTSTR sCmdLine = NULL, bool bCaseSensitive = false);
virtual ~CCmdLineParser ();
............... ............... ......
}

And following is the header of my main program:

#include "stdafx.h"
#using <mscorlib.dll >
#include "cmdlineparser. h" // for using of the command line parser class
using namespace System;

int _tmain(int argc, char* argv[]){
......
}

Thanks in advance!
