I am trying to format some c# output so that a number always has 2 digits for instance if int = 0
i would like Console.WriteLine(int);
to produce 00.

Take a look at http://msdn.microsoft.com/en-us/library/0c899ak8.aspx
This should do what you want:
int num = 10;
Console.WriteLine(num.ToString("0#"));
Console.ReadLine();
The string that is passed to the ToString method "0#" has the following meaning:
0 - 0 place holder, this will be replaced with relevant digit if one exists
# - digit place holder.
So if num is 0, 00 will be written to the console but if num is 10, 10 will be written to the console.

Take a look at this page, esp. the "Custom number formatting" section.
To show a number as two digits only you'd do something like this:
int x = 2;
string output = string.Format("{0:00}", x);
Console.WriteLine(output);

+1 for using string.Format instead of Console.WriteLine (more general solution)
