Question

I\'m trying to send an XML document over the wire but receiving the following exception:

\"MY LONG EMAIL STRING\" was specified for the \'Body\' element. ---         


        

Answer 1

byte[] toEncodeAsBytes
            = System.Text.ASCIIEncoding.ASCII.GetBytes(toEncode);
      string returnValue
            = System.Convert.ToBase64String(toEncodeAsBytes);

is one way of doing this

Answer 2

Can't the string be cleaned with:

System.Net.WebUtility.HtmlDecode()

?
