C# Converting a string value to a byte

I need a bit of help, How would I go about converting the below to a byte.

string s = "0x01";
byte b = Convert.toByte(s); //(Tried this) ??
byte c = byte.Parse(s); //(Tried this as well)

How would I convert s to a byte ?

Firstly, remove "0x" from the string value and then use parse() method with NumberStyles.HexNumber 

string s = "AA";
byte byteValue = 0; 
try
{
    byteValue = byte.Parse(s, NumberStyles.HexNumber | NumberStyles.AllowHexSpecifier);
}
catch (Exception e)
{
     Console.WriteLine(e);
}

Console.WriteLine("String value: 0x{0}, byte value: {1}", s, byteValue);

I guess the parse function won't allow the prefix 0X in the string so you might use sub-string to remove it.

byte myByte = Byte.Parse(s.SubString(2), NumberStyles.HexNumber);

Or use -

byte myByte = Convert.ToByte(s,16);
