Microsoft.Office.Server.Audience Namespace

  • Articolo

Contains classes that create Audiences and target data to a specific Audience.

In addition to rules-based audiences, Microsoft SharePoint Server 2010 supports targeting based on SharePoint groups and distribution list (DL) memberships. SharePoint Server 2010 also provides the ability to target content to the list item level, rather than just to the list level.

Note

SharePoint Server 2010 provides a Web service that finds all SharePoint sites that are targeted to a particular user. For more information, see How to: Use the Published Links Web Service.

Working with the New Namespace for the Audience Object Model

In SharePoint Portal Server 2003, the Microsoft.SharePoint.Portal.Audience namespace is used to work with audiences. In SharePoint Server 2010, the Audience object model is implemented in the Microsoft.Office.Server.Audience namespace in Microsoft.Office.Server.UserProfiles.dll. This new namespace provides object model support for the new functionality in SharePoint Server 2010.

The Microsoft.SharePoint.Portal.Audience namespace still exists for backward compatibility. Your applications and tools written in SharePoint Portal Server 2003 using the Microsoft.SharePoint.Portal.Audience namespace should still work in SharePoint Server 2010. However, note that they may not behave as expected, specifically with the new features. For example, if you use the APIs in Microsoft.SharePoint.Portal.Audience, you can only work with rules-based audiences. Therefore, if you are writing new applications or upgrading old applications, you should use the new Microsoft.Office.Server.Audience namespace in Microsoft.Office.Server.UserProfiles.dll. All the classes in the Microsoft.SharePoint.Portal.Audience namespace have been deprecated, and you will get a warning every time you use a class or method in the Microsoft.SharePoint.Portal.Audience namespace.

Example 2: Getting the AudienceManager Object in SharePoint Server

The AudienceManager object is the top-level object in the Audience object model. You can get an AudienceManager object in SharePoint Server 2010 by using the syntax shown in the following code example. Replace servername with an actual value and add any code that you might need before using this example.

using (SPSite site = new SPSite("https://servername"))
 {
   ServerContext context = ServerContext.GetContext(site);
   AudienceManager audManager = new AudienceManager(context);
   //your code here
 }

Example 2: Personalized Portals

The following code example shows how to target list items to a particular audience.

    AudienceLoader audienceLoader = AudienceLoader.GetAudienceLoader();
   foreach (SPListItem listItem in list.Items)
   {
    // Get roles the list item is targeted to.
     string audienceFieldValue = (string)listItem[k_AudienceColumn];

    // Quickly check if the user belongs to any of those roles.
     if (AudienceManager.IsCurrentUserInAudienceOf(audienceLoader, audienceFieldValue, false))
                {
                    // is a member
                }
                else
                {
                    // not a member
                }
  }
