Hi,

I'm creating an XmlDocument and trying to save it to a file. I find if I save via an XmlTextWriter or StreamWriter, I get 3 extra bytes at the beginning of the file. They are non-printable ascii, so they don't show up in a viewer, but the 3rd party import app doesn't like it.

IE,
XmlTextWriter writer = new XmlTextWriter(filename, System.Text.Encoding.UTF8);
xmlDoc.Save(writer);

If I call save with the filename directly, there are no extra bytes, but an element gets an extra xmlns="" attribute, which violates the schema.

IE, xmlDoc.Save(filename);
outputs ...
<SomeElement xmlns="">

Anyone seen this before? Any ideas on how to work around these? Thanks

That's the BOM. To suppress it, use the XmlTextWriter(Stream, Encoding) constructor, passing a StreamWriter for the Stream argumentthat you created with StreamWriter(String).
