TraceListener.Fail Method (String, String)


Emits an error message and a detailed error message to the listener you create when you implement the TraceListener class.

Namespace:   System.Diagnostics
Assembly:  System (in System.dll)

abstract Fail : 
        message:string *
        detailMessage:string -> unit
override Fail : 
        message:string *
        detailMessage:string -> unit


Type: System.String

A message to emit.

Type: System.String

A detailed message to emit.

The default behavior is to display the message and detailed message in a message box when the application is running in a user-interface mode, and to the TraceListener instances in a TraceListenerCollection collection. By default, the TraceListenerCollection collection has an instance of a DefaultTraceListener. You can customize this behavior by adding a TraceListener to or removing one from the collection.
