Question

How can I convert this string into a byte?

string a = "0x2B";

I tried this code, (byte)(a); but it said:

Cannot convert type string to byte…

And when I tried this code, Convert.ToByte(a); and this byte.Parse(a);, it said:

Input string was not in a correct format…

What is the proper code for this?

But when I am declaring it for example in an array, it is acceptable…

For example:

byte[] d = new byte[1] = {0x2a};

You have to specify the base to use in Convert.ToByte since your input string contains a hex number:

byte b = Convert.ToByte(a, 16);
