c#实现自定义window performance counter

下面是一个简单的实现 操作自定义window performance counter的实例。在运行程序的过程中我们通过操作系统的performance面板查看或者写log文件，对我们应用程序的性能进行监视，分析。将有助于我们分析解决系统的性能等问题。

代码功能： 

１，实现添加一个counter 类别

２，添加一个或者多个counter对象

３，获取counter对象，并赋值。

在系统的performance 面板中查看。效果如下图：

代码：

using System;
using System.Collections.Generic;
using System.Text;
using System.Threading;
using System.Diagnostics;

namespace WritePerformanceLog
{
    class Program
    {
        static void Main(string[] args)
        {
            if (!PerformanceCounterCategory.Exists("test_Category_1"))
            {
                // Create a collection of type CounterCreationDataCollection.
                System.Diagnostics.CounterCreationDataCollection CounterDatas =
                   new System.Diagnostics.CounterCreationDataCollection();
                // Create the counters and set their properties.
                System.Diagnostics.CounterCreationData cdCounter1 =
                   new System.Diagnostics.CounterCreationData();
                System.Diagnostics.CounterCreationData cdCounter2 =
                   new System.Diagnostics.CounterCreationData();
                cdCounter1.CounterName = "Counter1";
                cdCounter1.CounterHelp = "help string1";
                cdCounter1.CounterType = System.Diagnostics.PerformanceCounterType.NumberOfItems64;
                cdCounter2.CounterName = "Counter2";
                cdCounter2.CounterHelp = "help string 2";
                cdCounter2.CounterType = System.Diagnostics.PerformanceCounterType.NumberOfItems64;

                
                // Add both counters to the collection.
                CounterDatas.Add(cdCounter1);
                CounterDatas.Add(cdCounter2);
                // Create the category and pass the collection to it.
                System.Diagnostics.PerformanceCounterCategory.Create(
                   "test_Category_1", "Category help", CounterDatas);
            }
            else
            {

                PerformanceCounter cdCounter1 = new PerformanceCounter("test_Category_1", "Counter1", false);
                PerformanceCounter cdCounter2 = new PerformanceCounter("test_Category_1", "Counter2", false);
                
                cdCounter1.ReadOnly = false;

                for( int i=0;i<10000;i++ )
                {
                    cdCounter1.RawValue = i;
                    //cdCounter1.Increment();

                    cdCounter2.RawValue = i+1;

                    Thread.Sleep(100);
                }
                                           

                Console.WriteLine(cdCounter1.NextValue());
                Console.WriteLine(cdCounter2.RawValue);
                Console.WriteLine(cdCounter1.NextSample());


                Console.Read();

            }
        }
    }
}
