MFC CString轉int、double、char類型

轉自：【http://blog.csdn.net/mrandexe/article/details/6252080】

//CString轉int
CString szPort = L"2589";
int nPort = _ttoi(szPort);

//CString轉double
CString szPort = L"2589.00";
double nPort = _ttol(szPort);

//其它類型轉CString
int nPort = 2589;
char ip[32] = "這樣啊";
CString str;str.Empty();
str.Format(_T("%d:%s"), nPort, ip);

//CString轉TCHAR*
CString cstr(L"hello");
TCHAR *pstr = cstr.GetBuffer(str);
