How to convert a string to a byte array (C#)

System.Text.ASCIIEncoding encoding=new System.Text.ASCIIEncoding();
byte[] byteArray = encoding.GetBytes("your string");

The opposite conversion (byte array to string) looks like this:

System.Text.UnicodeEncoding enc = new System.Text.UnicodeEncoding();
string myString = enc.GetString(byteArray);
