Hexadecimal value 0x00 is a invalid character

Question

I am generating an XML document from a StringBuilder, basically something like:

string.Format(\"{0}{1}         


        

Answer 1

I also get the same error in an ASP.NET application when I saved some unicode data (Hindi) in the Web.config file and saved it with "Unicode" encoding.

It fixed the error for me when I saved the Web.config file with "UTF-8" encoding.
