路径转为转义字符串

eg: 将路径"C:\dir.txt"转为"C:\\dir.txt\0"

CString strpath="C:\dir.txt";  //unicode版本 CString strpath=L"C:\dir.txt";或者CString strpath=_T("C:\dir.txt");

strpath.Replace("\\","\\\\");   //strpath="C:\\dir.txt"; 

strpath+="\0";                    //strpath="C:\\dir.txt\0"; 

 

扩展：C#里 @代表后面字符串是转义字符串，strpath.Replace(@"\\",@"\\\\");  

string str=@"C:\dir.txt";  的结果为string str="C:\dir.txt"; 

string str=@"C:\\dir.txt";  的结果为string str="C:\dir.txt";
