Answer 1

Try turning the IEnumerable into a List. From this point on you will be able to use List's Remove method to remove items.

To pass it as a param to the Remove method using Linq you can get the item by the following methods:

• users.Single(x => x.userId == 1123)
• users.First(x => x.userId == 1123)

The code is as follows:

users = users.ToList(); // Get IEnumerable as List

users.Remove(users.First(x => x.userId == 1123)); // Remove item

// Finished
