I'm parsing some XML in C#. I'm getting it from a database, and so converting it to a MemoryStream before reading it with an XmlTextReader. The problem is that I get this error: Name cannot begin with the ' ' character, hexadecimal value 0x20. Line 1, position 3. Following is my XML and my code for reading it (it's coming out of the database alright, no blank first character). Any suggestions?

XML:

<? xml version="1.0" encoding="utf-8" ?>
<form>
   <e order="0" type="custom" name="test">
      <fi type="text" />
      <o />
   </e>
   <e order="1" type="zip" />
   <e order="2" type="state" />
</form>

C#:

byte[] byteArray = new byte[formXml.Length];
System.Text.UTF8Encoding encoding = new System.Text.UTF8Encoding();
byteArray = encoding.GetBytes(formXml);
MemoryStream xmlStream = new MemoryStream(byteArray);

XmlTextReader xmlReader = new XmlTextReader(xmlStream);
while (xmlReader.Read())
{
    if (xmlReader.HasValue)
    {
        returnString += xmlReader.Depth.ToString();
    }
}

I thought it could be the encoding, but I've tried by UTF8 and ASCII and can't find anything.

Yes, you should delete the space between <? and xml.

<?xml version="1.0" encoding="utf-8" ?>
<form>
   <e order="0" type="custom" name="test">
      <fi type="text" />
      <o />
   </e>
   <e order="1" type="zip" />
   <e order="2" type="state" />
</form>

Here's the relevant XML spec.

And the error message is (for once) completely spot on about the location of the problem.

Remove the first space in the document:

<?xml version="1.0" encoding="utf-8"?>

Your error message is quite explicit, you have an error at posn 3 in line 1. Try <?xml -- no space.
