VC++ 中 CT2A CA2T 两个宏进行字符串转换简单测试

#include "afxwin.h"
#include <iostream>

using namespace std;

int main()
{
    CString cs = _T("西游记");
    AfxMessageBox(_T("CString:") + cs);

    // CString 转 ACSII
    CT2A a_str(cs);
    string std_str(a_str);
    cout << "CString 转 string：" << std_str << endl;
    const char* pa_str = a_str;
    cout << "CString 转 const char *：" << pa_str << endl;

    // const char * 转 CString
    const char* a_char = "孙悟空";
    cout << endl << a_char << endl;
    CString wuKong(a_char);
    AfxMessageBox(_T("const char * 转 CString:") + wuKong);
    // string 转 CString  
    string baJie = "猪八戒";
    CString erShiXiong(baJie.c_str());
    AfxMessageBox(_T("string 转 CString:") + erShiXiong);

    // 用下面这种方式
    const char* sanShiDi = "沙和尚";
    CA2T sanShiDi_T(sanShiDi);
    CString wuJing(sanShiDi_T);
    AfxMessageBox(_T("const char * 转 CString:") + wuJing);

    return 0;
}
