How to use Scope Id in Sharepoint object model

If the lists items inherits permission or doesn’t inherit permission from the parent list or site, then the list items(including Sub folders) will have a same “ScopeID”

Based on the ACL i.e permissions, the scopeID displays a number

For Full Control permission, the below program returns the number 15.  
 
For View Only permission, the below program returns the number 1.  

   

Sample code:-


using (SPSite site = new SPSite("SiteURL"))
{
using (SPWeb web = site.OpenWeb())
{

SPList list = web.Lists["List_Name"];
Console.WriteLine("List name = {0}", list.Title);


SPQuery query = new SPQuery();
query.ViewFields = "";
query.ViewAttributes = "Scope='RecursiveAll'";

SPListItemCollection items = list.GetItems(query);

foreach (SPListItem item in items)
{
Console.WriteLine("{0} --> {1}",item["Title"],item["ScopeId"]);
}

Console.ReadKey();
}
}

How To Create an ECB menu to Wiki library in Sharepoint 2010
