之前做性能测试老是零零散散的一个Stopwatch，又一个Stopwatch，去测试方法的执行效率，从而进行验证。
为了方便使用，自己写一个好用的 性能测试类，目的在于方便好用，点到即可。
使用方式（如下，测试 NameValueCollection 与 Dictionary 的 性能）：
static void Main(string[] args) { Console.WriteLine(new Action(() => { NameValueCollection nvc = new NameValueCollection(); for (int j = 0; j < 10; j++) { nvc.Add(j.ToString(), j.ToString()); } for (int j = 0; j < 10; j++) { string temp = nvc[j.ToString()].ToString(); } }).ForWatchMS(100000)); Console.WriteLine(new Action(() => { Dictionary<string, string> nvc = new Dictionary<string, string>(); for (int j = 0; j < 10; j++) { nvc.Add(j.ToString(), j.ToString()); } for (int j = 0; j < 10; j++) { string temp = nvc[j.ToString()].ToString(); } }).ForWatchMS(100000)); } |
代码如下：
using System; using System.Diagnostics; public static class SpendTimeHelper { #region Action /// <summary> /// 执行forCount次的花费时间(ms) /// </summary> /// <param name="act"></param> /// <param name="forCount">执行次数</param> /// <returns>花费时间：毫秒</returns> public static long ForWatchMS(this Action act, long forCount) { Stopwatch watch = new Stopwatch();
