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

}

Once you filled-in target audience field , data are stored in "Audience" property of the underlying element (e.g. item, document, navigation node).

string audiencePropertyString = Convert.ToString(item.Properties["Audience"]);

Note that we use Convert.ToString() instead of .ToString() to avoid any null exception if the property does not exist.
