Remove an item from an IEnumerable collection

Question

I have a popuplated IEnumerable collection.

I want to remove an item from it, how can I do this?

foreach(var u in users)
{
          


        

Answer 1

There is now an extension method to convert the IEnumerable<> to a Dictionary<,> which then has a Remove method.

public readonly IEnumerable Users = new User[]; // or however this would be initialized

// To take an item out of the collection
Users.ToDictionary(u => u.Id).Remove(1123);

// To take add an item to the collection
Users.ToList().Add(newuser);
