Blow XmlTextWriter
Mmm... the following code causes a
System.NullReferenceException:
using (FileStream fs = new FileStream(@"e:\xmltextwriter.xml", FileMode.Create))
{
XmlTextWriter tw = new XmlTextWriter(fs, System.Text.Encoding.UTF8);
tw.WriteDocType("html",
"-//W3C//DTD XHTML 1.0 Transitional//EN",
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd",
null);
tw.WriteStartDocument();
tw.Flush();
}
The exception is thrown at the
WriteStartDocument() call. Of course the document being written is not valid according to the
Prolog and DTD Declaration specification in XML, but we should get a meaningful exception, right?
