Set "Target Audiences" field with multiple values on a List Item

Question

I am attempting to set the "Target Audiences" field on a list item programmatically. I have been able to set the value programmatically for one audience, but when I attempt to use multiple audiences, SharePoint tries to interpret the value I am setting as a single audience, rather than multiple. I am setting the value using the code below.

listItem[listItem.Fields["Target Audiences"].InternalName] = "Audience One";

I use this code to specify multiple audiences like so:

listItem[listItem.Fields["Target Audiences"].InternalName] = "Audience One; Audience Two";

When I do this, SharePoint tries to interpret the entire string as a single audience, and I get a message when I edit the list item that says "No exact match was found."

Am I using the correct format for specifying multiple audiences for this field, or is there a class that I should be using similar to SPFieldLookupValue?

Answer 1

I don't know how to save multiple audiences in a SPListItem, but if I had this problem, I'd try to print out the value of this field from a PowerShell script. Something like:

[System.Reflection.Assembly]::LoadWithPartialName("Microsoft.SharePoint");
$site = Microsoft.SharePoint.SPSite("http://yourserver");
$web = $site.openweb();
$list = $web.lists["YourList"];
$item = $list.getitembyid(itemid);
write-output $item["Target Audiences"];

EDIT: found some information about what the Audience field value actually is: http://dotnetmafia.sys-con.com/node/1181567/mobile

Kyle, could you post what your final solution was? I am facing the same problem as you.
