array numbers wich summ is deviding on 4

I want to print numbers on label from 1-to 100

The number's sum must be dividing on 4.

Example:
print 35. because 3+5 = 8 .
8 dividing on 4.

This is code
from loop printing numbers. but how choose those numbers?
print those numbers from 1 to 100 ;

for (int i = 1; i < 100; i++)
{
     //select numbers wich sum is dividing on 4
     label3.Text += Convert.ToString(i) + " | ";
}
