GetUserDataType

  • Article

Pushes the name of the current user data type onto the stack.

Syntax

  
<wf:Operation Name="GetUserDataType" />

Parameters

None.

Pushed Value

String containing the current user data type in assembly-qualified format.

Remarks

Unlike GetActivityType, this operation does not use the assembly-qualified class name format; instead, it pushes only the type name:

MyLibrary.MyObject

Note

If you use the assembly-qualified class name format as a constant when comparing values it will always evaluate to false.

Special Filter Behavior

When this operation is performed inside of a filter, derived user data types are always matched as well.

Example

The following sample contains an event filter expression that will evaluate to true for MyLibrary.MyObject instances and for any instances from classes that derive from MyLibrary.MyObject.

<ic:Filter>  
  <ic:Expression>  
    <wf:Operation Name="GetUserDataType" />  
    <ic:Operation Name="Constant">  
      <ic:Argument>MyLibrary.MyObject</ic:Argument>  
    </ic:Operation>  
    <ic:Operation Name="Equals" />  
  </ic:Expression>  
</ic:Filter>
