How do I insert an array entry at initialisation time?

Question

Given an array of strings, how do I create another array that has another entry inserted at initialisation time?

Eg. I want to do something like this:

var newArrayOfStrings = new string[] { "inserted entry", anotherArrayOfStrings }

(I know I can do this by getting a count and then copying; but I think it should be possible to do this at initialisation time.)

Answer 1

No, there's no special syntax for doing that. You'll need to do the copying in one way or another:

var newArrayOfStrings = 
        new[] { "inserted entry" }.Concat(anotherArrayOfStrings).ToArray();

_{Performance-wise, this can be slower than Array.Copy but the syntax is cleaner.}
