Binary to hex Conversion ?

[deadlyabbas]

Ho to convert binary to hex in C#. I have a byte array and I want to convert it into hex.

[Khaniya]

you can do it on this way

byte b = 15;
Console.WriteLine(b.ToString("X"));

The convert class can also be used for this:

Convert.ToString(number, base)

where base can be 2 (binary), 10 (decimal) or 16 (hexadecimal).

Thanks for your reply. If you just convert it as you have shown it Eliminates the "0". Say for example you have to convert 0000111111111000 into Hex.So it will show FF8 instead 0FF8 Well I was able to over come that by doing following:

string MyBinary = "0000111111111000";
string MyHex = String.Format("{0:X4}", Convert.ToInt32(MyBinary, 2));

When I need padding I use the string.PadLeft method. A couple of functions like this are all that's needed.

public static string ToHexString(int value)
{
return ToHexString(value, 0);
}
public static string ToHexString(int value, int bytes)
{
string result = Convert.ToString(value, 16);
if (bytes > 0)
result = result.PadLeft(bytes * 2, '0');
return result;
}

int b = 15;
string s=b.ToString("X8");

I advice to always specify the width you want; padding zeroes will be prefixed when necessary. :)
