例

次の例は、パラメーターとしてXmlObjectSerializerを含む WriteObjectWithInstance という名前のメソッドを示しています。 メソッドは、WriteObject メソッドを呼び出すことによって、DataContractSerializerまたはNetDataContractSerializerを使用してオブジェクトをシリアル化します。

public class Test
{
    private void WriteObjectWithInstance(XmlObjectSerializer xm, Company graph,
       string fileName)
    {
        // Use either the XmlDataContractSerializer or NetDataContractSerializer,
        // or any other class that inherits from XmlObjectSerializer to write with.
        Console.WriteLine(xm.GetType());
        FileStream fs = new FileStream(fileName, FileMode.Create);
        XmlDictionaryWriter writer = XmlDictionaryWriter.CreateTextWriter(fs);
        xm.WriteObject(writer, graph);
        Console.WriteLine("Done writing {0}", fileName);
    }

    private void Run()
    {
        // Create the object to write to a file.
        Company graph = new Company();
        graph.Name = "cohowinery.com";

        // Create a DataContractSerializer and a NetDataContractSerializer.
        // Pass either one to the WriteObjectWithInstance method.
        DataContractSerializer dcs = new DataContractSerializer(typeof(Company));
        NetDataContractSerializer ndcs = new NetDataContractSerializer();
        WriteObjectWithInstance(dcs, graph, @"datacontract.xml");
        WriteObjectWithInstance(ndcs, graph, @"netDatacontract.xml");
    }

注釈

XmlObjectSerializerを拡張して、オブジェクトをシリアル化および逆シリアル化する独自のシリアライザーを作成します。 DataContractSerializer クラスと NetDataContractSerializer クラスの両方がXmlObjectSerializerから継承され、データ コントラクト 規則に準拠するオブジェクト (DataContractAttributeとDataMemberAttributeを使用して作成されたオブジェクト) をシリアル化および逆シリアル化するために使用されます。

注意 (実装者)

XmlObjectSerializerから継承する場合は、WriteStartObject(XmlDictionaryWriter, Object)、WriteObjectContent(XmlDictionaryWriter, Object)、WriteEndObject(XmlDictionaryWriter)のメンバーをオーバーライドする必要があります。 さらに、読み取りと逆シリアル化のために、 IsStartObject メソッドと ReadObject メソッドを実装する必要があります。
