Linq ile xml namespace hatası

Generic handler dosyasında dinamik xml oluşturmak isterken root node'a xmlns atamak istediğimde aşağıdaki hatayı aldım "The prefix cannot be redefined from within the same start element tag, çözümü için aşağıdaki cevabı buldum. Xml namespace'i xml dökümanı oluşturmadan önce atamanız gerekiyor

XNamespace xn = "http://fake/namespace";

The prefix cannot be redefined from within the same start element tag

The following snippet of code had me stumped for a while:

XDocument xDoc = new XDocument(new XDeclaration("1.0",                                         "utf-8", "yes"),     new XComment("This is a comment"),     new XElement("elementName",         new XAttribute("xmlns", "http://fake/namespace"),         new XAttribute("version", "1.00"),         new XElement("innerelement",             new XAttribute("myAttribute", "att_value"))             )); // The prefix '' cannot be redefined from '' // to 'http://fake/namespace' // within the same start element tag.. string test = xDoc.ToString();

I was getting a  "The prefix '' cannot be redefined from '' to 'http://fake/namespace' within the same start element tag.." when running this.

The solution is to define the namespace before creating the XML document and prefixing this namespace to all elements that you create. Here is the working code.

XNamespace xn = "http://fake/namespace"; XDocument xDoc = new XDocument(new XDeclaration("1.0",                                         "utf-8", "yes"),     new XComment("This is a comment"),     new XElement(xn + "elementName",         new XAttribute("version", "1.00"),         new XElement(xn + "innerelement",             new XAttribute("myAttribute", "att_value"))             )); string test = xDoc.ToString(); Read more at guyellisrocks.com
