Convert number to hex

[rico14d]

Hi,

I'm trying to convert a number to its hex value which i can do with-
System.Convert.ToInt32(12323)

However, the number im trying to convert is much bigger (a MD5 hash result - 975415459309518814222848482335161230234) and the function errors.

Any ideas anyone.

Rich.

I don't actually see how the code you have written returns a hex value though...

The maximum size for an Int32 is 2,147,483,647. That hash value exceeds the size for any of the built-in .NET data types.

You may want to look at something like this:

The ComputeHash method on the MD5 class returns a byte array. What you can do is take each pair of bytes and convert them into a hex value:

  int i = 0;  
     // get bytes 0 and 1
  int16 bytePair = BitConverter.ToInt16(byteArray, i);
     // zero-pad the hex number!
  string hexString = bytePair.ToString("X02");

You'd then just loop thru your byte pairs, and concatenate your hex values together into one big string.
