ASP.NET in a Nutshell

Name

StackTrace

Synopsis

string = HttpException.StackTrace

Returns a string containing a list of the methods in the current call stack in which the exception occurred. The method in which the exception occurred is listed first, followed by any additional methods in the call stack (methods that called the method in which the exception occurred), up to the point at which the exception was handled.

Parameters

string

A string that will receive the stack trace value from the property.

Example

In the code example, the Page_Load event handler calls the ThrowMeAnException method, which throws an HttpException. The exception handler in Page_Load then displays the error message and stack trace:

Sub Page_Load(  )
   Try
      ThrowMeAnException
   Catch HttpEx As HttpException
      Message.Text = "ERROR:<br/>"
      Message.Text &= "Message: " & HttpEx.Message & "<br/>"
      Message.Text &= "Stack Trace: " & HttpEx.StackTrace & "<br/>"
   End Try
End Sub
Sub ThrowMeAnException(  )
   Throw New HttpException("Threw an error from ThrowMeAnException")
End Sub

Notes

The stack trace for the example first lists the ThrowMeAnException method, including the local path to the .aspx file containing the method and the line number at which the exception was thrown, and then lists the Page_Load method, including the path and line number where the exception originated.
