Converting string to byte

Question

BinaryConverter.ToString(byte[]) converts a byte array to a string such as AA-7E-81. Does anybody know how to do the reverse conversion? The obvious approach is to parse the string manully but I think .net framework could have something to facilitate this operation. I came across this problem when I needed to persist a byte array into an XML file. If anybody know the better approach than BinaryConverter.ToString please let me know.

You ment this i think :) string str_temp=askdjfkasdhfkasjd; char[] array_char = str_temp.ToCharArray(); byte[] array_byte = new byte[array_char.Length]; for(int i = 0; i < array_char.Length; i++) { array_byte[i] = (byte)array_char[i]; }

string str_temp=askdjfkasdhfkasjd; char[] array_char; array_char=string.ToCharArray(); byte[] array_byte; int i=0; foreach (char ch in array_char) { array_byte[i]=(byte)array_char[i]; i++; }

I think you can Convert string to byte: string str_temp=askdjfkasdhfkasjd; char[] array_char; array_char=string.ToCharArray(); byte[] array_byte; int i=0; foreach (char ch in array_char) { array_byte[i]=array_char[i]; i++; }

How about: Convert.ToByte(myStringToBeConverted) If you need a byte array you could do a myStringToBeConverted.ToCharArray() and then loop through the array and do a Convert.ToByte() on each element.
