Is it possible to extend arrays in C#?

Question

I\'m used to add methods to external classes like IEnumerable. But can we extend Arrays in C#?

I am planning to add a method to arrays that converts it to a IEnumera

Answer 1

Yes. Either through extending the Array class as already shown, or by extending a specific kind of array or even a generic array:

public static void Extension(this string[] array)
{
  // Do stuff
}

// or:

public static void Extension(this T[] array)
{
  // Do stuff
}

The last one is not exactly equivalent to extending Array, as it wouldn't work for a multi-dimensional array, so it's a little more constrained, which could be useful, I suppose.
