LINQ queries could easily solve this for you - make sure you're referencing System.Core.dll and have a

statement. For example, if you had your array in a variable named numberArray, the following code would give you exactly what you're looking for:

 var squares = numberArray.Select(n => n * n).ToArray();

The final "ToArray" call is only needed if you actually need an array, and not an IEnumerable.
