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 switch.

Examples

The following code sample shows how to display the custom attributes for a TraceSource. This code example is part of a larger example provided for the TraceSource class.

// Get the custom attributes for the TraceSource.
Console.WriteLine("Number of custom trace source attributes = "
    + ts.Attributes.Count);
foreach (DictionaryEntry de in ts.Attributes)
    Console.WriteLine("Custom trace source attribute = "
        + de.Key + "  " + de.Value);

' Get the custom attributes for the TraceSource.
Console.WriteLine("Number of custom trace source attributes = " + ts.Attributes.Count)
Dim de As DictionaryEntry
For Each de In ts.Attributes
    Console.WriteLine("Custom trace source attribute = " + de.Key + "  " + de.Value)
Next de

Remarks

The Attributes property identifies the custom attributes referenced in the application's configuration file. Unreferenced custom attributes are not enumerated. Classes that inherit from the TraceSource class can add custom attributes by overriding the Switch.GetSupportedAttributes method and returning a string array of custom attribute names.

The following is a sample of a trace source element specifying the custom attribute SecondTraceSourceAttribute:

<sources>  
  <source name="TraceTest" switchName="TestSourceSwitch"   
    switchType="Testing.MySourceSwitch, TraceSample"   
    SecondTraceSourceAttribute="two">  
  </source>  
</sources>
