The Return Type Matching Rule allows developers, operators, and administrators to select target classes based on the type name of the return value, using wildcard characters for the type name.

Note

The Policy Injection Application Block includes matching rule configuration placeholders that provide backward compatibility. The implementation of matching rules is described in the Unity Application Block documentation. For more information, see The Return Type Matching Rule in the Unity Application Block documentation.

Configuration Settings of the Return Type Matching Rule

The following configuration settings are available for the Return Type Matching Rule:

  • Match (String). This is the full namespace-qualified type name of the target object return type, or just the type name. The following are examples:
    • System.Int32
    • String
    • Int32
  • IgnoreCase (Boolean). This specifies whether the match should be carried out on a case-sensitive basis.

The next procedure describes how to configure the Return Type Matching Rule using the Configuration Console or the Visual Studio Configuration Editor.

To configure the Return Type Matching Rule

  1. Right-click the Matching Rules node in the Enterprise Library Configuration Console or Visual Studio Configuration Editor, point to New, and then click Return Type Matching Rule.
  2. In the right pane of the Enterprise Library Configuration Console, or in the Visual Studio Properties window, select the Name property, and then change the default name to the name you want to use for the new matching rule.
  3. Select the Match property and enter the full namespace and name of the type, such as System.String, or just the class name, such as String, that a method or property selected by the rule must return.
  4. Select the IgnoreCase property, and then click either True or False in the drop-down list to specify whether the match on the type name should be case-sensitive.
