How to Use This Example

Complete the following steps to review the code in this example:

  1. Open the Cast to More Generic Class sequence from the Sequences pane. Select the Cast to More Generic Class step, then click Edit in Visual Studio in the Module tab of the Step Settings pane to open the code module. This step casts a sequence file object to the more generic propertyObject and PropertyObjectFile classes to access their properties and methods.
  2. Open the Cast to More Specific Class sequence from the Sequences pane. Select the Cast to More Specific Class step, then click Edit in Visual Studio in the Module tab of the Step Settings pane to open the code module. This step casts a PropertyObject to more specific classes to access their properties and methods.
