c# - Code for adding to IEnumerable

Question

I have an enumerator like this

IEnumerable<System.Windows.Documents.FixedPage> page;

How can I add a page (eg: D: ewfile.txt) to it? I have tried Add, Append, Concat etc But nothing worked for me.

Answer 1

IEnumerable<T> does not contain a way to modify the collection.

You will need to implement either ICollection<T> or IList<T> as these contain an Add and Remove functions.
