C# 测试软件运行时间

以下是两种C#测试软件运行时间的例子：
1.获取程序运行时间

DateTime startTime = DateTime.Now;
// your code here
TimeSpan runTime = DateTime.Now.Subtract(startTime);
Console.WriteLine("程序运行时间为：" + runTime.TotalMilliseconds + "毫秒");

2.获取线程运行时间

DateTime startTime = DateTime.Now;
TimeSpan userTime = Process.GetCurrentProcess().Threads[0].UserProcessorTime;
// your code here
TimeSpan runTime = DateTime.Now.Subtract(startTime);TimeSpan threadTime = Process.GetCurrentProcess().Threads[0].UserProcessorTime.Subtract(userTime);
Console.WriteLine("程序运行时间为：" + runTime.TotalMilliseconds + "毫秒");
Console.WriteLine("线程运行时间为：" + threadTime.TotalMilliseconds + "毫秒");
