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

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

 2、int转CString

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

3、string转CString

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

4、CString转string

CString cstr = "hello";
string str = "";
str = cstr.GetBuffer(0);
cstr.ReleaseBuffer();
