.NET监视程序运行时间

使用Stopwatch类（命名空间：System.Diagnostics;）

示例：

?

using System;

using System.Collections.Generic;

using System.Configuration;

using System.Linq;

using System.Text;

using System.Threading.Tasks;

using SFast;

using System.Diagnostics;

 

namespace ConsoleApplication1

{

    class Program

    {

        static void Main(string[] args)

        {

            var sw = new Stopwatch();

            sw.Start();

            List<Employee> employees = new List<Employee>

            {

                new Employee {ID = 1, Name = "Ringgo"},

                new Employee {ID = 2, Name = "Rex"},

                new Employee {ID = 1, Name = "Ringgo"}

            };

            var reslut = employees.Distinct();

            sw.Stop();

            Console.WriteLine(sw.ElapsedTicks);

            Console.WriteLine(reslut._ToJsonStr());

            Console.ReadKey();

        }

    }

}

 结果：
