从.net创建xml文件

Question

我有下一个代码，尝试执行后遇到2个问题： 1. System.Xml.XmlException：'：'字符，十六进制值0x3A，不能包含在名称中。 2. base {System.SystemException} = {无法在同一个开始元素标记内从''重新定义前缀''从''到'urn = schemas-microsoft-com：office：excel'。} {“No se puede volver a definir el prefijo''de''a'urn = schemas-microsoft-com：office：excel'dentro de la misma etiqueta de elemento inicial。“}

我的代码是：

XDocument xdoc = new XDocument(new XDeclaration("1.0", "utf-8", "yes"),
   new XElement("Document", 
          new XElement("Worbook", 
               new XElement("DocumentProperties", new XElement("Author", "YO"),

                                                       new XElement("Company","CIA")),
