WCF c#中自定义类的传输问题

【中文标题】WCF c#中自定义类的传输问题【英文标题】：Problems with the transfer of custom class in WCF c# 【发布时间】：2019-10-17 02:25:37 【问题描述】：我正在服务器和客户端之间传输数据。客户端很容易从服务器接收到常用的数据类型，例如int，但是如果您将自定义类传递给它，则会收到以下异常：
System.ServiceModel.CommunicationException：获取对http://127.0.0.1:8000/Service 的 HTTP 响应时出错。这可能是由于服务端点绑定不使用 HTTP 协议造成的。这也可能是由于 HTTP 请求上下文已被服务器中断（可能是由于服务被禁用）。有关详细信息，请参阅服务器日志。
我尝试了许多解决方案来解决这些问题，但没有任何帮助。
我在类字段中添加了 getter 和 setter，将 DataContract 等更改为 Serializable：
自定义类
namespace c_CardStrategy
[DataContract]
public class Card
#region ПОЛЯ
[DataMember]
public string Name get; set;
[DataMember]
public string Effect get; set;
[DataMember]
public int ID get; set;
[DataMember]
public int Price get; set;
[DataMember]
public string EffText get; set;
#endregion
#region Конструктор
public Card(int id, string name, string effect, int price, string efftext)
Price = price;
ID = id;
Name = name;
Effect = effect;
EffText = efftext;
public Card()
Name = "";
Effect = "";
ID = 0;
Price = 0;
EffText = "";
#endregion
[DataContract]
public class Moster_Card : Card
[DataMember]
public int? Health get; set;
[DataMember]
public int? Power get; set;
public Moster_Card(int id, string name, int? health, int? power, string effect, int price, string efftext) : base(id, name, effect, price, efftext)
Health = health;
Power = power;
public Moster_Card()
Name = "";
Effect = "";
ID = 0;
Price = 0;
EffText = "";
Health = 0;
Power = 0;
[DataContract]
public class Spell_Card : Card
[DataMember]
public int? Charge get; set;
public Spell_Card(int id, string name, string effect, int price, string efftext, int? charge) : base(id, name, effect, price, efftext)
Charge = charge;
public Spell_Card()
Name = "";
Effect = "";
ID = 0;
Price = 0;
EffText = "";
Charge = 0;

int? Power = Card.Card_power;
int? Charge = Card.Charge;
if (Health != null)
Cards.Add(new Spell_Card(id, name, eff, price, efftext, Charge));
else
Cards.Add(new Moster_Card(id, name, Health, Power, eff, price, efftext));
return Cards;

客户
public partial class DecksWindow : Window
private GameClient Client;
public DecksWindow(GameClient client)
InitializeComponent();
Client = client;
private void New_deck_Click(object sender, RoutedEventArgs e)
Deck_list.Visibility = Visibility.Visible;
List<Card> Cards = new List<Card>();
try
Cards = Client.GetAllCards() as List<Card>;
foreach (Card Card in Cards)
StackPanel Sp = new StackPanel();
Sp.Height = 170;
Sp.Width = 150;
Sp.Margin = new Thickness(0, 5, 5, 0);
Sp.Background = Brushes.Red;
Sp.Tag = Card.IDk__BackingField.ToString();
Sp.Uid = 2.ToString();
Deck_list.Children.Add(Sp);
catch (Exception ex)
tb.Text += ex.Message;
//tb.Text = Client.Checkuser("Admin", "Admin").ToString();

【问题讨论】：
您的Card 类必须是DataContract，以便您可以在客户端看到class。每个属性也需要DataMember 属性。请注意，我从未在WCF 服务中使用过派生类，所以我不确定派生类是否也需要DataContract，但我相信它也应该拥有它。
@Franck，已经这样做了，但没有帮助[DataContract] public class Card #region ПОЛЯ [DataMember] public string Name get; set; [DataMember] public string Effect get; set; ...
我知道这对您的错误没有帮助。但是您的代码将需要它在客户端工作，因为您具有该对象的返回类型。如果类不是DataContract 和DataMember，它将不起作用。您的错误是与您的绑定有关的通信错误。您需要将您的 web.config 添加到帖子中，以便有人可以提供帮助。
@Franck，更新了主题，添加了配置。感谢您的提示
我怀疑你的服务器正在使用你的客户端正在使用的 basicHttpBinding。
【参考方案1】：
您可以在托管服务后访问 Web 服务的 WSDL 吗？ 我怀疑配置可能太简单了。我建议您在服务器端应用以下配置。
<system.serviceModel>
<services>
<service name="YourNamespace.GameServer " behaviorConfiguration="mybehavior">
<endpoint address="http://localhost:8000/Service" binding="basicHttpBinding" contract="YourNamespace.IGame " ></endpoint>
<endpoint address="http://localhost:8000/Service/mex" binding="mexHttpBinding" contract="IMetadataExchange"></endpoint>
</service>
</services>
<behaviors>
<serviceBehaviors>
<behavior name="mybehavior">
<serviceMetadata httpsGetEnabled="true" httpGetEnabled="true" />
<serviceDebug includeExceptionDetailInFaults="true" />
</behavior>
</serviceBehaviors>
</behaviors>
</system.serviceModel>
托管服务后，我们可以通过在浏览器地址栏中输入服务地址来访问服务信息。
http://localhost:8000/service
此外，我们在托管服务时可能需要管理权限。 如果问题仍然存在，请随时告诉我。
