방법: XmlSerializer를 사용하여 serialize

이 항목에서는 XmlSerializer를 사용하여 serialize하고 deserialize하는 예제를 보여 줍니다.

예

다음 예제에서는 XElement 개체가 포함된 많은 개체를 만든 다음메모리 스트림으로 개체를 serialize하고 메모리 스트림에서 개체를 deserialize합니다.

using System.Linq;

using System.Xml.Linq;

public class XElementContainer
{
    public XElement member;

    public XElementContainer()
    {
        member = XLinqTest.CreateXElement();
    }

    public override string ToString()
    {
        return member.ToString();
    }
}

public class XElementNullContainer
{
    public XElement member;

    public XElementNullContainer()
    {
    }
}

class XLinqTest
{
    static void Main(string[] args)
    {
        Test<XElementNullContainer>(new XElementNullContainer());
        Test<XElement>(CreateXElement());
        Test<XElementContainer>(new XElementContainer());
    }

    public static XElement CreateXElement()
    {
        XNamespace ns = "https://www.adventure-works.com";
        return new XElement(ns + "aw");
    }

    static void Test<T>(T obj)
    {
        using (MemoryStream stream = new MemoryStream())
        {
            XmlSerializer s = new XmlSerializer(typeof(T));
            Console.WriteLine("Testing for type: {0}", typeof(T));
            s.Serialize(XmlWriter.Create(stream), obj);
            stream.Flush();
            stream.Seek(0, SeekOrigin.Begin);
            object o = s.Deserialize(XmlReader.Create(stream));
            Console.WriteLine("  Deserialized type: {0}", o.GetType());
        }
    }
}

Public Class XElementContainer
    Public member As XElement

    Public Sub XElementContainer()
        member = XLinqTest.CreateXElement()
    End Sub

    Overrides Function ToString() As String
        Return member.ToString()
    End Function
End Class

Public Class XElementNullContainer
    Public member As XElement

    Public Sub XElementNullContainer()
        member = Nothing
    End Sub
End Class

Public Class XLinqTest
    Shared Sub Main()
        Test(Of XElementNullContainer)(New XElementNullContainer())
        Test(Of XElement)(CreateXElement())
        Test(Of XElementContainer)(New XElementContainer())
    End Sub

    Public Shared Function CreateXElement() As XElement
        Dim ns As XNamespace = "https://www.adventure-works.com"
        Return New XElement(ns + "aw")
    End Function

    Public Shared Sub Test(Of T)(ByRef obj)
        Using stream As New MemoryStream()
            Dim s As XmlSerializer = New XmlSerializer(GetType(T))
            Console.WriteLine("Testing for type: {0}", GetType(T))
            s.Serialize(XmlWriter.Create(stream), obj)
            stream.Flush()
            stream.Seek(0, SeekOrigin.Begin)
            Dim o As Object = s.Deserialize(XmlReader.Create(stream))
            Console.WriteLine("  Deserialized type: {0}", o.GetType())
        End Using
    End Sub
End Class

이 예제는 다음과 같이 출력됩니다.

Testing for type: XElementNullContainer
  Deserialized type: XElementNullContainer
Testing for type: System.Xml.Linq.XElement
  Deserialized type: System.Xml.Linq.XElement
Testing for type: XElementContainer
  Deserialized type: XElementContainer
