一,先开启开始或继续测量某个时间间隔的运行时间,然后停止,最后重置时间,输出.
using System;
using System.Collections.Generic;
using System.Diagnostics;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
public partial class TestPerformance : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
/*Var 性能测试 */
Stopwatch stw = new Stopwatch();
List<long> intlist = new List<long>();
stw.Start();
for (long i = 0; i < 10000000; i++)
{
var index = i;//使用var转入和转出
intlist.Add(index);
}
stw.Stop();
Label1.Text= stw.Elapsed.Ticks.ToString();
stw.Reset();
/*Int 性能测试 */
List<long> intlist2 = new List<long>();
stw.Start();//开始时间
for (long i = 0; i < 1000000; i++)
{
long index = i;//使用int转入和转出
intlist2.Add(index);
}
stw.Stop();
Label2.Text = stw.Elapsed.Ticks.ToString();
stw.Reset();
/*Object性能测试 */
stw.Start();//开始时间
List<long> intlist3 = new List<long>();
for (long i = 0; i < 1000000; i++)
{
object index = i;//使用object转入和转出
intlist3.Add((long)index);
}
stw.Stop();
Label3.Text = stw.Elapsed.Ticks.ToString();
}
}
二,前端显示
