even odd numbers using foreach

Hello Friends,

How can we generate even odd series using foreach loop.
so far my code is:

public void forEachLoop()
{
Console.WriteLine("Enter Starting point:");
first = int.Parse(Console.ReadLine());
Console.WriteLine("Enter Ending point:");
last = int.Parse(Console.ReadLine());
int[] array = new int[last];
foreach (int num in array)
{
array[first] = first;
array[last] = last;
array[first] += 2;
Console.WriteLine(array[first]);


if (array[first] == array[last])
break;
}

}

Please help,Thank you.

Code:

---

//print the even numbers between 0 and 100
for(int i=0;i<=50;i++)
  Console.WriteLine(2*i);

---

Or:

Code:

---

//print the odd numbers between 0 and 100
foreach(int i in Enumerable.Range(0, 50))
  Console.WriteLine(2*i+1);

---

Thanks.
