Update the Scope Using Core Service

Question

I have a user and some groups. I am able to add the groups and with specific scope to the user using core service. What do i do if i need to add a group with all publications as its scope using core service. Below is my sample code.

GroupData group1 = CoreServiceClient.Read("tcm:0-187-65568", null) as GroupData;
UserData userData = CoreServiceClient.Read("tcm:0-49-65552", null) as UserData;

GroupMembershipData groupmembership1 = new GroupMembershipData();

LinkToGroupData linktogroupData1 = new LinkToGroupData();
linktogroupData1.IdRef = group1.Id;
linktogroupData1.Title = group1.Title;

groupmembership1.Group = linktogroupData1;

LinkWithIsEditableToRepositoryData pubLink1 = new LinkWithIsEditableToRepositoryData();
pubLink1.IdRef = "tcm:0-1-1";
pubLink1.Title = "Content";

LinkWithIsEditableToRepositoryData pubLink2 = new LinkWithIsEditableToRepositoryData();
pubLink2.IdRef = "tcm:0-3-1";
pubLink2.Title = "Design";

LinkWithIsEditableToRepositoryData[] pubArray1 = { pubLink1, pubLink2 };
groupmembership1.Scope = pubArray1;

GroupMembershipData[] groupArray = { groupmembership1 };
userData.GroupMemberships = groupArray;

CoreServiceClient.Save(userData, null);

Answer 1

If you want the Group to be available in all Publications (including future ones), simply leave the Scope property alone. The default value is the same as checking that "(All Publications)" checkbox on the editing screen.

Answer 2

The questions narrows down to how to get all publications:

var allPublications = CoreServiceClient.GetSystemWideList(new RepositoryFilterData()); 

And now just assign it:

groupmembership1.Scope = allPublications.Select(pub => new LinkWithIsEditableToRepositoryData{ IdRef = pub.Id }).ToArray();

I was writing it without checking first, so there might be some typos
