How to Construct a Web Message Part from a Primitive .NET Type

  • Article

You create a Web message part from a primitive .NET type by using a Message Assignment shape. Alternatively, you can create a Web message part from a primitive .NET type by using a .NET helper class to set the parts. For more information on creating message types by using a .NET class, see Constructing Messages in User Code.

To construct a Web message part from a primitive .NET type

  1. With an orchestration open, open the Toolbox and click the BizTalk Orchestrations tab.

  2. Drag a Construct Message shape to the orchestration.

  3. Edit the Message Constructed property to include the message instance that you created for the Web message type.

  4. Drag a Message Assignment shape onto the Construct Message shape.

  5. Double-click the Message Assignment shape to open the BizTalk Expression Editor.

  6. Set the parts of the Web message type to their required values in the BizTalk Expression Editor box.

    For example, the following code sets the expression to a string:

    ItemAvailRequestInstance.Item_ID = "This is Item_ID.";
