计算两个日期之间的时间？

Question

有人可以帮我做这项工作吗？

我想在VB.NET中计算两个日期之间的时间，如下所示：

startdate: 2011/12/30  
enddate: 2011/12/31  

计算：？小时？一分钟？秒

Answer 1

你可以尝试这个

DateTime startTime = DateTime.Now;

DateTime endTime = DateTime.Now.AddSeconds( 75 );

TimeSpan span = endTime.Subtract ( startTime );
Console.WriteLine( "Time Difference (seconds): " + span.Seconds );
Console.WriteLine( "Time Difference (minutes): " + span.Minutes );
Console.WriteLine( "Time Difference (hours): " + span.Hours );
Console.WriteLine( "Time Difference (days): " + span.Days );

输出赞，

Time Difference (seconds): 15
Time Difference (minutes): 1
Time Difference (hours): 0
Time Difference (days): 0

VB.Net等同于上面的内容：

Dim startTime As DateTime = DateTime.Now

Dim endTime As DateTime = DateTime.Now.AddSeconds(75)

Dim span As TimeSpan = endTime.Subtract(startTime)
Console.WriteLine("Time Difference (seconds): " + span.Seconds)
Console.WriteLine("Time Difference (minutes): " + span.Minutes)
Console.WriteLine("Time Difference (hours): " + span.Hours)
Console.WriteLine("Time Difference (days): " + span.Days)

当你减去2 DateTime时，你会得到一个TimeSpan结构，其中包含所有这些属性。
