Definition

Namespace:

System.Diagnostics

Assembly:

System.Diagnostics.PerformanceCounter.dll

Gets or sets the name of the custom counter.

public:
 property System::String ^ CounterName { System::String ^ get(); void set(System::String ^ value); };

public string CounterName { get; set; }

member this.CounterName : string with get, set

Public Property CounterName As String

Property Value

String

A name for the counter, which is unique in its category.

Exceptions

ArgumentNullException

The specified value is null.

ArgumentException

The specified value is not between 1 and 80 characters long or contains double quotes, control characters or leading or trailing spaces.

Examples

The following code example demonstrates how to get and set the CounterName property. This example creates two counters and sets their CounterName property by using different techniques. When the first counter is initialized, the CounterName data is passed to the constructor, whereas the second counter sets the property explicitly.

#using <System.dll>

using namespace System;
using namespace System::Diagnostics;

int main()
{
   CounterCreationDataCollection^ myCol = gcnew CounterCreationDataCollection;
   
   // Create two custom counter objects.
   CounterCreationData^ myCounter1 = gcnew CounterCreationData( "Counter1","First custom counter",PerformanceCounterType::CounterDelta32 );
   CounterCreationData^ myCounter2 = gcnew CounterCreationData;
   
   // Set the properties of the 'CounterCreationData' Object*.
   myCounter2->CounterName = "Counter2";
   myCounter2->CounterHelp = "Second custom counter";
   myCounter2->CounterType = PerformanceCounterType::NumberOfItemsHEX32;
   
   // Add custom counter objects to CounterCreationDataCollection.
   myCol->Add( myCounter1 );
   myCol->Add( myCounter2 );
   if ( PerformanceCounterCategory::Exists( "New Counter Category" ) )
      PerformanceCounterCategory::Delete( "New Counter Category" );
   
   // Bind the counters to a PerformanceCounterCategory.
   PerformanceCounterCategory^ myCategory = PerformanceCounterCategory::Create( "New Counter Category", "Category Help", myCol );
   Console::WriteLine( "Counter Information:" );
   Console::WriteLine( "Category Name: {0}", myCategory->CategoryName );
   for ( int i = 0; i < myCol->Count; i++ )
   {
      // Display the properties of the CounterCreationData objects.
      Console::WriteLine( "CounterName : {0}", myCol[ i ]->CounterName );
      Console::WriteLine( "CounterHelp : {0}", myCol[ i ]->CounterHelp );
      Console::WriteLine( "CounterType : {0}", myCol[ i ]->CounterType );
   }
