請幫忙！無法添加性能計數器 - 「添加」按鈕被禁用

Question

我已經使用Entlib 4.1創建了性能計數器，如下所示。當我打開performon.exe和添加計數器時 - 我可以看到我創建的性能對象和計數器列表。但是我不能添加它們，因爲添加按鈕被禁用。任何建議？

public class Program 
{ 
    static void Main(string[] args) 
    { 
     Console.WriteLine("You are about to install the performance counters"); 
     InstallPerformaceCounters(); 
     Console.ReadLine(); 


     for (int i = 0; i < 100000; i++) 
     { 
      if (i % 3 == 2) 
      { 
       Thread.Sleep(100); 
      } 

      if (i % 5 == 2) 
      { 
       Thread.Sleep(1000); 
      } 

      PerformSearch(i); 
     } 

     Console.ReadLine(); 
    } 

    private static void PerformSearch(int i) 
    { 
     Console.WriteLine(i); 
    } 

    private static void InstallPerformaceCounters() 
    { 
     try 
     { 
      PerformanceCountersInstaller installer = new PerformanceCountersInstaller(new SystemConfigurationSource()); 
      IDictionary state = new System.Collections.Hashtable(); 
      installer.Context = new InstallContext(); 
      installer.Install(state); 
      installer.Commit(state); 
      Console.WriteLine("Performance counters have been successfully installed."); 
     } 
     catch (Exception ex) 
     { 
      throw ex; 
     } 
    } 
}

這是我的錯誤。我需要運行該應用程序，特別是用這些計數器裝飾的方法，所以我可以將計數器添加到列表中。
