c# - How to add a new counter to an existing performance counter category without deleting the old counters? -

I have a custom counter category, which I need to add a new counter, without deleting or resetting any existing counter for. how can I do this?

I tried using CounterExists (), but even after I made the counter, how can I associate it to a CounterCreationDataCollection item and associate my current counter class?

I found, especially, because there does not seem to be much information on this subject The best way to do this is to protect the existing raw values ​​and then delete the category and then re-apply it after it has been rebuilt.

  /// & lt; Summary & gt; The removal of the /// category requires the need to preserve the existing counter values ​​/// & lt; / Summary & gt; Fixed dictionary & lt; String, long & gt; GetPreservedValues ​​(string category, XmlNodeList nodes) {dictionary & lt; String, long & gt; Protected Price = New Dictionary & lt; String, long & gt; (); Foreach (XmlNode countersource in nodes) {string counterName = counterNode.Attributes ["name"]. Values; If (PerformanceCounterCategory.CounterExists (counterName, category)) {PerformanceCounter performanceCounter = New PerformanceCounter (Category, counterName, False); Protected Price Add (CounterName, Performance Counter. Rowwall); Protecting {0} with a cratele of console (lightning "{1}", counter name, display counter Rowwall);} Else {Console.WriteLine ("Unable to preserve {0} because it does not exist" CounterName);}} Returns protected value;} /// & lt; summary & gt; /// Restore preserved values ​​after the re-created category /// & lt; / summary & gt; static void SetPreservedValues (String category, dictionary & lt; string; long & gt; preservedValues) {foreach (KeyValuePair & lt; string, From time to time> SavedValues ​​stored in Values ​​{PerformanceCounter performanceCounter = New PerformanceCounter (category, preservedValue.Key, false); DisplayConverter.Raval Price = Protected Price; Console.WriteLine ("Restoring {0} With a RawValue of {1} ", preservedValue.Key, performanceCounter.RawValue);}}
