Hi

I asked the question a while back on how to convert a byte[] to a string looking something like 0x3130353030353032.

The solution was

C#

myTextBox.Text="0x";
foreach(byte b in array)
{
  myTextBox.Text += b.ToString("X2");
}

now I would please like to know how would I convert that string back to a byte[]

Thanks in advanced

Use code block for code segment.

Two hints:

1) As you should know, a byte takes two hexadecimal digits to be presented as a hexadecimal string. Split your string into the array of two-digit strings; the length of this array will give you the length of the byte[] array you should initialize.

2) To parse a string into byte, use byte.Parse(string, NumberStyles), use System.Globalization.NumberStyles.HexNumber.
