How do I convert a C# class to an XMLElement or XMLDocument

I have an C# class that I would like to serialize using XMLSerializer. But I would like to have it serialized to a XMLElement or XMLDocument. Is开发者_运维百科 this possible or do I have to serialize it to a String and then parse the string back to a XMLDocument?

I had this problem too, and Matt Davis provided a great solution. Just posting some code snippets, since there are a few more details.

Serializing:

public static XmlElement SerializeToXmlElement(object o)
{
    XmlDocument doc = new XmlDocument();

    using(XmlWriter writer = doc.CreateNavigator().AppendChild())
    {
        new XmlSerializer(o.GetType()).Serialize(writer, o);
    }

    return doc.DocumentElement;
}

Deserializing:

public static T DeserializeFromXmlElement<T>(XmlElement element)
{
    var serializer = new XmlSerializer(typeof(T));

    return (T)serializer.Deserialize(new XmlNodeReader(element));
}

You can create a new XmlDocument, then call CreateNavigator().AppendChild(). This will give you an XmlWriter you can pass to the Serialize method that will dump into the doc root.

Public Shared Function ConvertClassToXml(source As Object) As XmlDocument
    Dim doc As New XmlDocument()
    Dim xmlS As New XmlSerializer(source.GetType)
    Dim stringW As New StringWriter
    xmlS.Serialize(stringW, source)
    doc.InnerXml = stringW.ToString
    Return doc
End Function
Public Shared Function ConvertClassToXmlString(source As Object) As String
    Dim doc As New XmlDocument()
    Dim xmlS As New XmlSerializer(source.GetType)
    Dim stringW As New StringWriter
    xmlS.Serialize(stringW, source)
    Return stringW.ToString
End Function
Public Shared Function ConvertXmlStringtoClass(Of T)(source As String) As T
    Dim xmlS As New XmlSerializer(GetType(T))
    Dim stringR As New StringReader(source)
    Return CType(xmlS.Deserialize(stringR), T)
End Function
Public Shared Function ConvertXmlToClass(Of T)(doc As XmlDocument) As T
    Dim serializer = New XmlSerializer(GetType(T))
    Return DirectCast(serializer.Deserialize(doc.CreateNavigator.ReadSubtree), T)
End Function
