获得双斜杠路径不包含文件名春肆

TCHAR _szPath[MAX_PATH + 1]={0}

GetModuleFileName(NULL, _szPath, MAX_PATH)

（_tcsrchr(_szPath, _T('\\')))[1] = 0//删除文件名，只获得路径 字串

CString strPath

for (int n=0_szPath[n]n++)

{

if (_szPath[n]!=_T('\\'))

{

strPath +=_szPath[n]

}

else

{

strPath += _T("\\\\")

}

}

MessageBox(strPath)//输出==e:\\program\\Debug\扒败轿\
