String to long

[willemr]

Hi guys,


I have another problem with the RFID types.

I have a program that delivers me the RFID in a string

string RFID = 003000d4;

But I have to get it in a long called RFIDlong, it tried several thing I found on the net.

RFIDlong = convert.toInt64(RFID);
RFIDlong = long.parse(RFID);

And some other, but nothin has worked.


Can anyone help please?

Did you tried

Convert.ToInt64(RFID,16);

Yeah indeed, now it works.

For the record, this also works:

string num = "003000d4";
long l = long.Parse(num, System.Globalization.NumberStyles.HexNumber);

The issue seems to be the fact that the number is HEX. If it were not, then either of the things you tried first would work.

I showed you how to properly format a hex number to become an int in the other thread you started on this problem. That is why we ask you to not start multiple threads on the same problem, because it divides efforts to help you. Look at the code in the first thread.
