 property System::Collections::Specialized::StringDictionary ^ Attributes { System::Collections::Specialized::StringDictionary ^ get(); };

member this.Attributes : System.Collections.Specialized.StringDictionary
Public ReadOnly Property Attributes As StringDictionary

Property Value

StringDictionary

A StringDictionary containing the custom attributes for the trace listener.

Remarks

Classes that inherit from the TraceListener class can add custom attributes by overriding the GetSupportedAttributes method and returning a string array of custom attribute names. The Attributes property identifies the custom attributes that are referenced in the application's configuration file. For example, in the following configuration file excerpt the DelimitedListTraceListener custom attribute "delimiter" is referenced. In this case, the Attributes property returns a StringDictionary containing the string "delimiter".

<listeners>
  <add name="delimitedListener"
    type="System.Diagnostics.DelimitedListTraceListener"
    delimiter=":"
    initializeData="delimitedOutput.txt"
    traceOutputOptions="ProcessId, DateTime" />
  <remove name="Default" />
</listeners>

Unreferenced custom attributes are not enumerated. For more information, see the GetSupportedAttributes method.
