I'd use else ifs instead of ifs otherwise you'd get unnecessary repitition.

for (Int32 i = 1; i <= 100; i++)
{
if (i % 3 == 0 && i % 5 == 0)
Console.WriteLine(i + " is a multiple of both 3 AND 5!");
else if (i % 3 == 0)
Console.WriteLine(i + " is a multiple of 3");
else if (i % 5 == 0)
Console.WriteLine(i + " is a multiple of 5");

}

i.e you get:

12 is a multiple of 3
15 is a multiple of both 3 AND 5!
18 is a multiple of 3

instead of this:

12 is a multiple of 3
15 is a multiple of both 3 AND 5!
15 is a multiple of 3
15 is a multiple of 5
18 is a multiple of 3
Opps! Miss that. Indeed.

I guarantee every programming course has that exercise.
Let's do that one next then. An array of 10 random numbers should be fine...

I'll try tomorrow.
