array as parameters

Question

write a Separate method should take an integer array and swap the element in that array until it contains the even numbers sorted followed by the odd number sorted.

For example and array containing 3, 4, 2, 1, 5 should end us as 2, 4, 1, 3, 5.

 

using System;

namespace HelloWorld
{
class Program
{
static string GetArrayAsString(int[] array)
{
if(array.Length == 0) return "";

string str = "";
int i = 0;
for(; i < array.Length - 1; i++)
{
str += array[i] + ", ";
}
str += array[i];

return str;
}

static void Main(string[] args)
{
int[] numbers = {3, 4, 2, 1, 5};
Separate(numbers);
Console.WriteLine(GetArrayAsString(numbers));
}
}
}
