Question

I have an array of Foo objects. How do I remove the second element of the array?

I need something similar to RemoveAt() but for a regular array.

If you don’t want to use List:

var foos = new List<Foo>(array); foos.RemoveAt(index); return foos.ToArray(); 

You could try this extension method that I haven’t actually tested:

public static T[] RemoveAt<T>(this T[] source, int index) {     T[] dest = new T[source.Length - 1];     if( index > 0 )         Array.Copy(source, 0, dest, 0, index);      if( index < source.Length - 1 )         Array.Copy(source, index + 1, dest, index, source.Length - index - 1);      return dest; } 

And use it like:

Foo[] bar = GetFoos(); bar = bar.RemoveAt(2);
