1. QString strBuffer;  
2. QDateTime time;  
3.   
4. time = QDateTime::currentDateTime();  
5.   
6. strBuffer = time.toString("yyyy-MM-dd hh:mm:ss");  
7.   
8. // strBuffer = 2010-07-02 17:35:00  

QString strBuffer; QDateTime time; time = QDateTime::currentDateTime(); strBuffer = time.toString("yyyy-MM-dd hh:mm:ss"); // strBuffer = 2010-07-02 17:35:00

 

2、QString 转换为 QDateTime
