converting a 2 bytes hexadecimal value to an integer

[mayaanu]

Hai
I am writing an application that reads the data from the serial port in to a byte array(example bf).I had converted the byte array to string using
string s=Bitconverter.Tostring(bf)
Now i want to get an integer value from 0th and 1st bytes in bytearray.
the values that comes in my bytearray are
bf[0]=165
bf[1]=03
when it is converted to string it will be A503
i need an integer from bf[0] and bf[1].
please help me
thanks in advance

Look at the BitConverter class. It looks like it needs a byte array where the LSB is in the first index. So in your case, if you're looking to get A503, you'll want to have 03 in index 0 and 165 in index 1.

            byte[] arr = new byte[] { 03, 165 };
            ushort v = BitConverter.ToUInt16(arr, 0);
 
            Console.WriteLine("Value: " + v.ToString());
            Console.WriteLine("Value (Hex): " + v.ToString("X"));
