【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。

【问题讨论】：

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。 ***.com/questions/140149/…

【参考方案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
