combine string.format arguments

I want to generate a 4 character hex number.

To generate a hex number you can use 

string.format("{0:X}", number)

and to generate a 4 char string you can use 

string.format("{0:0000}", number)

Is there any way to combine them?

Have you tried:

string hex = string.Format("{0:X4}", number);

? Alternatively, if you don't need it to be part of a composite pattern, it's simpler to write:

string hex = number.ToString("X4");

I'm assuming you mean: 4-digit hexadecimal number.

If so, then yes:

string.Format("{0:X4}", number)

should do the trick.
