How to: Add Complex Rules to an Audience Using AND, OR, ( and ) Operators

Applies to: SharePoint Server 2010

The user interface provides you with only two options for defining rules for audiences: include users that satisfy all rules, or include users that satisfy any rules. Although this might be enough for some situations, most often you will need to include users that satisfy complex rules. Complex rules use both AND and OR operators, and they may also use parentheses ( ) to group the rules to give them a different meaning.

In cases in which you need to create complex rules, you can use the Audience object model. The object model supports up to a maximum of three levels of nesting of parentheses.

The following code example adds complex rules for an audience called "John and Joe Connection". This example uses AND, OR, and ( and ) operators to combine multiple rules and to group rules.

Replace servername and other strings with actual values before running the code example. Also add the following references in your Microsoft Visual Studio project:

• Microsoft.Office.Server

• Microsoft.Office.Server.UserProfiles

• Microsoft.SharePoint

• System.Web
