How to Create Expressions

  • Článek

BizTalk Expression Editor enables you to create XLANG/s expressions to expand the capabilities of various Orchestration Designer shapes. You can create XLANG/s expressions to make decisions, set delays, make .NET calls, and test while loop conditions.

It enables you to assign values to messages or message parts in the Message Assignment shape, and to make .NET calls and manipulate the values of variables in the Expression shape. You can also use it to construct complex Boolean expressions in the Loop and Decide shapes, and to set a delay in the Delay shape.

To open BizTalk Expression Editor

  1. Right-click an Expression shape, a Loop shape, a Message Assignment shape, a Delay shape, or a branch of a Decide shape.

  2. Click Edit Expression.

  3. BizTalk Expression Editor appears.

To create or edit an expression

  1. Type or edit the expression in the text field of BizTalk Expression Editor.

  2. Click OK. This saves the expression and applies it to the selected shape.
