You can create a query to retrieve a list of banned users in both open and group channels. Only users registered as channel operators may use the following code.
SbBannedUserListQueryParams queryParams = new SbBannedUserListQueryParams(); SbBannedUserListQuery query = channel.CreateBannedUserListQuery(queryParams); query.LoadNextPage((inUsers, inError) => { if (inError != null) { return; // Handle error. } });
