How to write xml file like this format?

I want write code in c# which i need to get like this .

<Email version="2.00" xmlns="http://www.portalfiscal.inf.br/nfe"> </Email>

I have tried this but not exact.

XmlTextWriter writer = new XmlTextWriter("D:\\nefe.xml", System.Text.Encoding.UTF8);
writer.WriteStartDocument();
writer.WriteStartElement("Email");
writer.WriteString("version=2.00  xmlns=Http://www.portalfiscal.inf.br/nfe");
writer.WriteEndElement();
writer.WriteEndDocument();
writer.Close();

and output this code is giving like this

 <Email>version=2.00 xmlns=Http://www.portalfiscal.inf.br/nfe</Email>

Well yes - you're calling WriteString, which writes text content. Your sample XML contains attributes, so you should be using WriteAttributeString:

writer.WriteAttributeString("version", "2.00");
writer.WriteAttributeString("xmlns", "http://www.portalfiscal.inf.br/nfe");

Do you have to use XmlWriter though? Personally I'd recommend using LINQ to XML if you possibly can. It's not as suitable for writing enormous documents which XmlWriter can handle easily, but it's much cleaner when you're just trying to create a simple document of moderate size:

XNamespace ns = "http://www.portalfiscal.inf.br/nfe";
var doc = new XDocument(new XElement(ns + "Email",
                                     new XAttribute("xmlns", ns.ToString()),
                                     new XAttribute("version", "2.00")));
doc.Save("nefe.xml");

If you do insist on using XmlWriter, you should use a using statement to make sure the output is always closed even if an exception is thrown.

The method you're looking for on XmlTextWriter is WriteAttributeString

XmlTextWriter writer = new XmlTextWriter("D:\\nefe.xml", System.Text.Encoding.UTF8);
writer.WriteStartDocument();
writer.WriteStartElement("Email");
writer.WriteAttributeString("version","2.00");
writer.WriteAttributeString("xmlns","Http://www.portalfiscal.inf.br/nfe");
writer.WriteEndElement();
writer.WriteEndDocument();
writer.Close();
