MFC中CString和string的相互转换

//将CString转为std::string
string CMyUtil::CString2string(const CString &cstr)
{
CStringA stra((TCHAR *)(LPCTSTR)(cstr));
string str((char *)(LPCSTR)(stra));

return str;
}

//将std::string转为CString
CString CMyUtil::string2CString(const string &str)
{
CString cstr(str.c_str(), str.length());

return cstr;
}

//将CString转为std::string（walker认为没必要这样用）
string CMyUtil::CString2string(CString cstr)
{
CStringA stra(cstr.GetBuffer(0));
cstr.ReleaseBuffer();

string str = stra.GetBuffer(0);
stra.ReleaseBuffer();

return str;
}
