Sort array of items using OrderBy<>

Question

I have an array of items and I would like to sort on one of their properties. I can access the items property using \"item.Fields[\"FieldName\"].Value\" the propert

Answer 1

To be clear, OrderBy won't sort the array in place - it will return a new sequence which is a sorted copy of the array. If that's okay, then you want something like:

var sorted = array.OrderBy(item => item.Fields["FieldName"].Value);

On the other hand, I don't understand your comment that the property is returned as a string but that you can cast it to an int - you can't cast strings to ints, you have to parse them. If that's what you meant, you probably want:

var sorted = array.OrderBy(item => int.Parse(item.Fields["FieldName"].Value));

If you want that as an array, you can call ToArray() afterwards:

var sorted = array.OrderBy(item => int.Parse(item.Fields["FieldName"].Value))
                  .ToArray();

Alternatively you could use Array.Sort if you want to sort in-place, but that will be somewhat messier.
