Hex with leading zeros to string?

How can one format an integer into a hex string with leading zeros? Suppose
an integer is 512 which in Hex is 200. I wish to print the 4-byte integer
as 0200 or even 0x0200. The HEX function doesn't create leading zeros. The
Format function (format(value,"X") doesn't create leading zeros.

I believe there should be a simple way that doesn't involving measuring and
padding the string.

How about

Hex(value).PadLeft(4, "0"c) ?

Al, Thanks loads. It seems a little hokey but it works just like it is
documented.

Hi Rich

String.Format("{0:X4}", value)

Value.ToString("X4")

Thanks to all for the three options. I like Value.ToString("X4") best but I
also like the padleft method for other uses.

Having done mostly VB6, I am new to .Net programming and am interested in
recommended books that would contain these kinds of details.

I like the String.Format(...) version, myself ;-)
