The or operator there would be doing a binary or http://en.wikipedia.org/wiki/Bitwise_operation

From looking I am not sure if this is what you actually want. Can you explain what you are hoping to have happen here?

Cheers,

Is rows[0]["StudentID"] integer?

int a = 100;
int b = 110;
int c = a|b;

this gives me 110 as expected.

Try changing your code to this


int val = Int32.Parse( rows[0]["studentID"]);

int val = val | KM;

rows[0]["studentID"] = Convert.ToString(val);

int Km = 0;
 rows[0]["StudentID"] =  rows[0]["studentID"]  | int.Parse(Km.ToString());  

this is the equivalent of a nop as Km is always 0... anything | 0 = anything

beyond that you could simplify this further with

rows[0]["StudentID"] |= Km;

assuming that rows[0]["StudentID"] is an integer which its impossible to tell from your code example.


Cheers,

Greg
