ThrowActivity Class
Models the throwing of an exception. This class cannot be inherited.
Assembly: System.Workflow.ComponentModel (in System.Workflow.ComponentModel.dll)
The purpose of the ThrowActivity is to allow declarative modeling of the throwing of an exception. The ThrowActivity is functionally equivalent to a CodeActivity activity whose code-beside handler throws the indicated exception.
The following code shows the use of a single throw activity in a workflow to implement exception handling. This code example is part of the Throw SDK sample and is from the ThrowWorkflow.cs file. For more information, see Using Throw.
