获取当前日期时间字符串的方法

CString GetTimeStr()
{
        CTime time;
        // 获取当前时间
        time = CTime::GetCurrentTime();
        CString sTime;
        // 格式化时间串
        sTime = time.Format("%Y/%m/%d,%H:%M:%S  ");
        return sTime;
}

 

由于使用了CString，故使用该函数需要MFC支持

 

调用该函数得到的日期时间串例子如下：

 

2009/07/08,17:18:06 

 

 格式化时间串中各个参数的含义如下：
