Trace.Fail Method (String, String)
Emits an error message, and a detailed error message.
Assembly: System (in System.dll)
[<ConditionalAttribute("TRACE")>] static member Fail : message:string * detailMessage:string -> unit
Parameters
- message
-
Type:
System.String
A message to emit.
- detailMessage
-
Type:
System.String
A detailed message to emit.
The default behavior is for the default trace listener to output the message parameter and the detailedMessage parameter to a message box when the application runs in user-interface mode, and to the TraceListener instances in the Listeners collection.
Note |
|---|
The display of the message box is dependent on the presence of the DefaultTraceListener. If the DefaultTraceListener is not in the Listeners collection, the message box is not displayed. The DefaultTraceListener can be removed by the <clear> Element for <listeners> for <trace>, the <remove> Element for <listeners> for <trace>, or by calling the Clear method on the Listeners property (System.Diagnostics.Trace.Listeners.Clear()). |
You can customize this behavior by adding a TraceListener to, or by removing one from, the Listeners collection.
