How to get an indexed item of an IEnumerable object (Linq)
If you have an IEnumerable<T> collection of some objects T and you need to get a particular item out of that collection, you cannot use the standard indexing that you would normally use with brackets ([index]). If you try you will get an error such as:
Cannot apply indexing with [] to an expression of type ‘System.Collections.Generic.IEnumerable<T>
But there is the extension method ElementAt(index) (in the System.Linq namespace) for IEnumerable<T> that will allow you to get at that particular indexed item:
MyItem = MyIEnumerableExpression.ElementAt(index);
