Throw Statement

Syntax

Throw exception

exception (required; Exception or derived from Exception)

A System.Exception object representing the exception being thrown

Description

The Throw statement initiates an exception that can be handled using either structured

exception handling (with a

Try...Catch...Finally statement) or unstructured error

handling (with an

On Error statement).

Example

Dim positiveNumber As Integer

Try

' ----- Throw an exception if the user enters anything other

' than a positive number.

positiveNumber = CInt(InputBox("Enter number of items."))

If (positiveNumber <= 0) Then

Throw New Exception("Entry must be a positive number.")

End If

Catch ex As Exception

MsgBox(ex.Message)

End Try

Version Differences

The Throw statement is new to VB under .NET.
