Question

I got a list of objects in the following query. How to delete items in the middle, saying I want to delete item in 2, 5, and 7 position? thanks

            var archivedPwds = from archivedPwd in db.PasswordArchive
                               where archivedPwd.UserId == userId
                               orderby archivedPwd.DateChanged
                               select archivedPwd;

EDIT:

I am using L2E and want to delete those items from database.

Answer 1

You cannot “delete” items from an IEnumerable or IQueryable. What you can do is filter them out, or build another collection out of the filtering results.

Filtering by index is still done by Where:

var indexesToFilterOut = new[] { 2, 5, 7 };
var filtered = archivedPwds.Where((pwd, i) => !indexesToFilterOut.Contains(i));
