All data present in 16 bytes for e.g name = 16 bytes , cell = 16 bytes ...
If i want to convert it in hexa how can i get the bytes for e.g i want to pick the data
from 1 to 16 is for NAME, then 17 to 32 is fir CELL .... and so on
Guide me in a code how i get this bytes in sequence so that i can add the data in database.
Thanks

## Solution 1

The following code will convert a string of hex characters into their actual values. You may need to modify according to the format of your source string.
```// source = hex bytes
int i = 0;
int index = 0;
byte[] hexBytes = new byte[source.Length];
do
{
string hs = source.Substring(index, 2);
hexBytes[i] = (byte)int.Parse(hs, System.Globalization.NumberStyles.AllowHexSpecifier);
i++;
index += 2;
} while (index < source.Length);```

This
```public static string from_hex(string s)
{
StringBuilder sb = new StringBuilder();
string [] a = s.Split( new  char[]{' '});
foreach (var h in a)
{
sb.Append((char) int.Parse(h, System.Globalization.NumberStyles.HexNumber));
}
return sb.ToString();
}```

should do the trick.

I have done conversion but i want take values from packet how can i detect
for e.g. byte 1-16 is name and byte 17-32 is cell no and byte 33-48 is cnic.
