  • Where does it throw exception ? On which line ? – MD. Khairul Basar Jan 17 '20 at 10:12
  • Check for the line: `var memberToGroup = db.MemberToGroups.Where(mtg => mtg.memberId == id).FirstOrDefault(); if (memberToGroup.memberId == id)`. – Sisir Jan 17 '20 at 10:13
  • If your `db` doesn't have the item matching the `id` it will return NULL. In the next line when u use `memberToGroup` without checking for it will trow NUllReferenceException because it has become NULL from previous line – Sisir Jan 17 '20 at 10:15
  • `var memberToGroup = db.MemberToGroups.Where(mtg => mtg.memberId == id).FirstOrDefault();` can return null so you need to verify that, `if(!memberToGroup.any())`-like condition. – anastaciu Jan 17 '20 at 10:16
