遞增自定義性能計數器.net 4.0 Windows 7

我在Windows 7上增加了自定義性能計數器時遇到了一些麻煩。創建了類別，創建了計數器，但調用了「Increment（）」或設置了「RawValue」沒有看似的效果。例如，Increment（）的返回值仍然爲0L。遞增自定義性能計數器.net 4.0 Windows 7

以下代碼是控制檯應用程序，需要以管理員身份運行以創建類別。調試通過顯示以上症狀。

任何幫助，非常感謝。

class Program 
{ 
    private static string _category = "MyCustomCounters"; 

    static void Main(string[] args) 
    { 
     var deleteIfExists = false; 

     if (args.Any()) 
     { 
      if (args.Count() > 0) 
      { 
       _category = args[0]; 
      } 

      if (args.Count() > 1) 
      { 
       deleteIfExists = args[1].ToUpper() == bool.TrueString.ToUpper(); 
      } 
     } 

     CreateCustomCounters(_category, deleteIfExists); 
    } 

    private static void CreateCustomCounters(string category, bool deleteIfExists) 
    { 
     if (deleteIfExists && PerformanceCounterCategory.Exists(category)) 
     { 
      PerformanceCounterCategory.Delete(category); 
     } 

     if (!PerformanceCounterCategory.Exists(category)) 
     { 
      CounterCreationDataCollection counterCollection = new CounterCreationDataCollection(); 

      // add a counter tracking operations per second 
      CounterCreationData opsPerSec = new CounterCreationData(); 
      opsPerSec.CounterName = "# requests /sec"; 
      opsPerSec.CounterHelp = "Number of requests executed per second"; 
      opsPerSec.CounterType = PerformanceCounterType.RateOfCountsPerSecond32; 
      counterCollection.Add(opsPerSec); 

      // add a counter tracking operations per second 
      CounterCreationData operationTotal = new CounterCreationData(); 
      operationTotal.CounterName = "Total # requests"; 
      operationTotal.CounterHelp = "Total number of requests executed"; 
      operationTotal.CounterType = PerformanceCounterType.NumberOfItems32; 
      counterCollection.Add(operationTotal); 

      PerformanceCounterCategory.Create(category, 
         "A custom counter category that tracks execution", PerformanceCounterCategoryType.SingleInstance, 
         counterCollection); 
     } 
     else 
     { 
      Console.Error.WriteLine("Counter already exists, try specifying parameters for categoryname and or insisting on deleting"); 
     } 

     using (var _totalOperationsCounter = new PerformanceCounter(_category, "Total # requests", false)) 
     { 
      _totalOperationsCounter.ReadOnly = false; 
      _totalOperationsCounter.RawValue = 10; 
      var count = _totalOperationsCounter.Increment(); 
     } 
    } 
}

爲我的行爲作爲follwed（我沒有設置RawValue）

當性能監視器不運行
- Console.WriteLine(_totalOperationsCounter.Increment())顯示器始終爲1
時性能監視器IS正在運行
- Console.WriteLine(_totalOperationsCounter.Increment())應用程序之間的增量運行
