C# ONLY PLEASE

Given an array of integers, create a method that return an array that contains the exact same numbers as the given array, but rearranged so that all the zeros are grouped at the start of the array. The order of the non-zero numbers does not matter. You may modify and return the given array or make a new array. So {1, 0, 0, 1} becomes {0, 0, 1, 1}. For example, if your array is { 0, 1, 1, 0, 1 }, the zero front array will be { 0, 0, 1, 1, 1 } because all the zeros have been transferred to the beginning of the array.

USE: static int[] ZeroFront(int[] a)
