How to convert this hex string into a long?

Question

I have: "0xE94C827CEB" in hex but as a string.

Which is: 1002011000043 (dd mm yyyy HH mm ss)

Unfortunately I don't know how to do the conversion if I only have it in string format, and I don't have a Convert.ToLong("0xE94C827CEB", 16) function because I'm using the .NET Micro Framework (also, don't have NumberStyles namespace available.)

Is there a function out there that will convert this for me?

Thanks

I don't know of any function to do it, but I think you can do it quite simply by splitting the hex string and passing each part through Convert.ToInt32():

int part1 = Convert.ToInt32("E9", 16)
int part2 = Convert.ToInt32("4C827CEB", 16) //the last 4 bytes
long result = part1 * 4294967296 + part2  //4294967296 being 2^32. Result = 1002011000043
