我有一个非常简单的应用程序,它目前有一个基于单个表的Linq到Sql类。

我该怎么做?

    var db = new MyEntityDataContext();
    Stream fs = new FileStream("Output.xml", FileMode.Create);
    XmlWriter writer = new XmlTextWriter(fs, Encoding.Unicode);            

    serializer = new XmlSerializer(typeof(MyEntity));
    foreach (var row in db.MyEntitys)
    {
        // Serialize object to XML
        serializer.Serialize(writer,row);
    }

    writer.Close();

"Token StartElement in state Epilog would result in an invalid XML document."

XmlSerializer serializer2 = new XmlSerializer(db.MyEntitys.GetType());

"To be XML serializable, types which inherit from IEnumerable must have an implementation of Add(System.Object) at all levels of their inheritance hierarchy."

XmlSerializer 与他人交往可能并不美妙。如果在数据上下文表面上启用序列化,则会添加(WCF)数据契约属性。也许只是使用:

var data = db.MyEntitys.ToList();
var ser = new DataContractSerializer(data.GetType());
ser.WriteObject(dest, data);
