【问题描述】：

我已在我的应用程序中添加了性能自定义计数器以操作是否发生的次数。

但现在我想注销它。是否可以注销它删除它。

我在 C# 中使用过这个计数器。

创建性能类别的类和为其添加计数器。

using System;
using System.Diagnostics;

namespace GroupChatLibrarySamples
{
    ///<summary>
    ///Helper class to demonstrate the setup of performance counters.
    ///</summary>
    public class PerformanceCounterHelper
    {
        //Total number of tests executed
        private PerformanceCounter _TotalFiles = null;
        /// <summary>
        /// Constructor
        /// </summary>
        public PerformanceCounterHelper()
        {
            // Set up the performance counter(s)
             if (!PerformanceCounterCategory.Exists("Total_Files","."))
             {
                //Create the collection container
                CounterCreationDataCollection counters = new CounterCreationDataCollection();
                ////Create counter #1 and add it to the collection
                CounterCreationData tests = new CounterCreationData();
                tests.CounterName = "Total_Files_Sent";
                tests.CounterHelp = "Total number of Files Sent";
                tests.CounterType = PerformanceCounterType.NumberOfItems32;
                counters.Add(tests);

                //Create the category and all of the counters.
                PerformanceCounterCategory.Create("Total_Files", "Performance Counter for checking no of files sent", counters);
             }
             try
             {
                 _TotalFiles = new PerformanceCounter();
                 _TotalFiles.CategoryName = "Total_Files";
                 _TotalFiles.CounterName = "Total_Files_Sent";
                 _TotalFiles.MachineName = ".";
                 _TotalFiles.ReadOnly = false;
             }
             catch (Exception e)
             {
                 Console.WriteLine(" {0} \n", e.StackTrace);

             }

        }


        public void IncrementCounters()
        {
            _TotalFiles.Increment();

        }
    }
}

计数器递增的代码：

    private void BeginSendFilesFinished(IAsyncResult ar) 
    {

        currentOperation.End("BeginSendFilesFinished", () => session.EndUploadFile(ar)); 
        Console.WriteLine(" File Count  : {0} \n", listoffiles.Count);
        if(sentFiles <  (listoffiles.Count-1))
        {
                sentFiles++;  
                string SampleFile = listoffiles[sentFiles].ToString();
                FileInfo filetoupload = new FileInfo(SampleFile);                        
                ChatRoomFileUploadJob uploadfilejob = new ChatRoomFileUploadJob(filetoupload);
                counterHelper.IncrementCounters();   
                currentOperation.Begin(string.Format("Send Files: # {0}", sentFiles), () => session.BeginUploadFile(uploadfilejob, BeginSendFilesFinished, null));

        }
        else
        {
            Log("Leave ChatRoom:");
            // After sending 10 chat msgs, leave the chat room (and rejoin).
            currentOperation.Begin("Leave ChatRoom:", () => session.BeginLeave(BeginLeaveChatRoomFinished, null));
        }
    }

感谢和问候，塔齐姆。

Could you please provide us the code where you register it?
我已经添加了这个计数器，并使用 perfmon 监控它。但我想删除它知道或删除它或取消注册它。是否可以？任何链接和指针都将是有价值的。提前致谢
可以删除计数器。 stackoverflow.com/questions/140149/…

【解决方案1】：

这可能太明显了，但考虑到您正在尝试执行与 PerformanceCounterCategory.Create 操作相反的操作（我认为），您是否考虑过使用 PerformanceCounterCategory.Delete？根据文档：

删除类别及其来自本地的相关计数器电脑
