MFC 与 C++ 类型转换

C++ 中到的类型转换很多，先记录下来，多了写成一个类

1、CString转int

1 CString cNum="9527";
2 int iNum = 0;
3 iNum=atoi(LPCTSTR(cNum));

2、int转CString

1 int iNum = 2211;
2 CString strNum = "";
3 strNum.Format("%d", iNum);

3、string转CString

1 string str = "hello";
2 CString cstr = "";
3 cstr = str.c_str();

4、CString转string

1 CString cstr = "hello";
2 string str = "";
3 str = cstr.GetBuffer(0);
4 cstr.ReleaseBuffer();
