WCF xmlSerializer和數據合同屬性

Question

我使用XSD2Code從給定的XSD生成C＃代碼。該工具生成的代碼剪斷如下：

[System.CodeDom.Compiler.GeneratedCodeAttribute("System.Xml", "4.0.30319.1")] 
    [System.SerializableAttribute()] 
    [System.ComponentModel.DesignerCategoryAttribute("code")] 
    [System.Xml.Serialization.XmlTypeAttribute(AnonymousType = true)] 
    [System.Xml.Serialization.XmlRootAttribute(Namespace = "", IsNullable = false)] 
    public partial class Orders 
    { 

     [System.Xml.Serialization.XmlElementAttribute(Form = System.Xml.Schema.XmlSchemaForm.Unqualified, Order = 0)] 
     public int OrderID {get;set;} 
     [System.Xml.Serialization.XmlElementAttribute(Form = System.Xml.Schema.XmlSchemaForm.Unqualified, Order = 1)] 
     public string Description {get;set;} 
    } 

Coud有人請指導我用以下queires，請

1. 如果我離開了上面的代碼，因爲它是不WCF序列化上面的類？ 目前我得到的WCF測試客戶端上這樣的錯誤：「」此操作不 在WCF測試客戶端支持」

2. 我是否需要添加DataContract和DataMember上述生成的代碼的頂部

？
3. 哪個選項是DataContract串行器之間尤爲明顯VS XML序列 謝謝你。

Answer 1

1. 它應該工作，只要合同（無論是服務合同接口或使用這種類型的操作方法合同）標有[XmlSerializerFormat]屬性
2. 沒有 - 如果你[XmlSerializerFormat]裝飾合同，DataContract /的DataMember屬性被忽略（XML序列化的屬性，像這種類型的人，是用來代替）
3. 的XmlSerializer允許你完全控制類型序列化的XML; DataContractSerializer（DCS）沒有（它更受限制）。但是DCS具有更好的性能，所以哪個更好取決於你的情況。

下面的代碼顯示了使用此類型的服務，即使使用WcfTestClient，它也可以正常工作。

     ChannelFactory<ITest> factory = new ChannelFactory<ITest>(new BasicHttpBinding(), new EndpointAddress(baseAddress)); 
     ITest proxy = factory.CreateChannel(); 

     Console.WriteLine(proxy.GetOrders()); 

     ((IClientChannel)proxy).Close(); 
     factory.Close(); 

     Console.Write("Press ENTER to close the host"); 
     Console.ReadLine(); 
     host.Close();
