ASP.NET in a Nutshell

Name

GetBaseException

Synopsis

Exception = HttpException.GetBaseException( )

Returns an Exception object representing the original exception in a set of nested exceptions. This property provides a shortcut to the innermost exception accessible via the InnerException property.

Parameters

Exception

An Exception instance that will be populated by the method.

The code throws the third exception, which is caught by the Catch statement. The Catch block displays the error message of both the immediate inner exception by using the InnerException property and the original exception by using the Message property of the exception returned by the GetBaseException method:

Sub Page_Load( ) Try Dim myHttpEx As _ New HttpException("This is the original exception") Dim myHttpEx2 As _ New HttpException("This is a nested exception", myHttpEx) Throw New HttpException("Threw an exception from Page_Load", _ myHttpEx2) Catch HttpEx As HttpException Dim InnerHttpEx As HttpException InnerHttpEx = CType(HttpEx.InnerException, HttpException) Message.Text = "ERROR:<br/>" Message.Text &= "Message: " & HttpEx.Message & "<br/>" Message.Text &= "Inner Exception Message: " & _ InnerHttpEx.Message & "<br/>" Message.Text &= "Base Exception Message: " & _ InnerHttpEx.GetBaseException.Message & "<br/>" End Try ...
