Set all array values to 0 with Lambda/linq

Question

Is it possible to set all int array values to 0 with Lambda/Linq?

public int[] Reset()
{
    int[] M = new int[MIlg]; \\MIlg - length of array
    for (int i = 0; i < M.Length; i++)
    {
        M[i] = 0;
    }
    return M;
}

As an aside, I would strongly advise you to use more meaningful names - MIlg is a very obscure name, IMO. — Jon Skeet

In c#, new array of int will always create continuous block of int with 0 value. — Akash Kava

LINQ is inherently about querying, not modifying. But there's already a method that does this - Array.Clear:

Array.Clear(array, 0, array.Length);

That's assuming you want to clear an existing array, of course. Your current method doesn't make much sense, as a new array already starts with every element set to the default, so you can just use new int[length]. I'd expect a method called Reset to affect an existing array.
