GetActivityName

  • Article

Pushes the name of the current activity onto the stack.

Syntax

  
<wf:Operation Name="GetActivityName"/>

Parameters

None.

Pushed Value

String containing the current activity name.

Remarks

Windows Workflow Foundation performs its work as a series of activities configured by the developer. Each of these activities is assigned a unique name within the workflow. You can intercept data for a specific activity by filtering based on its unique name.

Example

The following sample contains an event filter expression configured to find a specific activity—FoodAndDrinksPolicy—in a Closed workflow. This is done by using a combination of operations including GetActivityName, GetActivityEvent, and logical operations.

<ic:Filter>  
  <ic:Expression>  
    <wf:Operation Name="GetActivityName"/>  
    <ic:Operation Name="Constant">  
      <ic:Argument>FoodAndDrinksPolicy</ic:Argument>  
    </ic:Operation>  
    <ic:Operation Name="Equals"/>  
    <wf:Operation Name="GetActivityEvent"/>  
    <ic:Operation Name="Constant">  
      <ic:Argument>Closed</ic:Argument>  
    </ic:Operation>  
    <ic:Operation Name="Equals"/>  
    <ic:Operation Name="And"/>  
  </ic:Expression>  
</ic:Filter>

This filter pattern is common with Windows Workflow Foundation interceptor configuration files.

Note

Arguments do not require quotation marks unless you are explicitly trying to match a string that contains quotation marks.
