Assembly: System.Activities (in System.Activities.dll)
'Declaration Public Shared Function Invoke(Of TResult) ( _ workflow As Activity(Of TResult) _ ) As TResult
The type of the workflow.
A value of type TResult with the result of the execution of the activity.
The following example invokes a workflow consisting of a single Add activity that has two input arguments and since it derives from CodeActivity<int> it has one well-defined Result output argument. When the workflow is invoked, the arguments dictionary is passed which contains the values for each input argument, keyed by argument name. When the call to Invoke returns, the value of the Result output argument is returned. This code example is based off of the Using the WorkflowInvoker Class sample.
