CString直接转换为const char *

CString casts to const char * directly

CString temp;
temp = "Wow";
const char * foo = (LPCSTR) temp;
printf("%s", foo);

将打印'foo'

版本的MFC也支持GetString（）方法：

Newer version of MFC also support the GetString() method:

CString temp;
temp = "Wow";
const char * foo = temp.GetString();
printf("%s", foo);
