[英]“The type RoleProxy was not expected. Use the XmlInclude or SoapInclude attribute to specify types that are not known statically.” NHibernate
[英]WCF service throws “The type […] was not expected. Use the XmlInclude […]” even if XmlInclude is already being used
我有一個WCF服務(從代碼開始),該服務使用服務定義中未定義的對象。 因此,我必須使用[XmlInclude]
屬性使WCF理解如何對其進行序列化。 由於某種原因,這不起作用,WCF仍然抱怨(我使用跟蹤發現了異常)我必須對已定義的類型使用[XmlInclude]
。
我在這里想念什么?
ServiceHost host = new ServiceHost(typeof(MyService), "http://localhost/myservice");
ServiceMetadataBehavior smb = new ServiceMetadataBehavior();
smb.HttpGetEnabled = true;
smb.MetadataExporter.PolicyVersion = PolicyVersion.Policy12;
host.Description.Behaviors.Add(smb);
host.Open();
[WebService(Namespace = "http://services.mysite.com/MyService")]
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
[System.ComponentModel.ToolboxItem(false)]
public class MyService : WebService, IMyService {
[WebMethod]
[XmlInclude(typeof(InnerObject))]
public MyReturnObject Test() {
return new MyReturnObject(new InnerObject());
}
}
[ServiceContract]
public interface IMyService {
[OperationContract, XmlSerializerFormat(Style = OperationFormatStyle.Document)]
MyReturnObject Test();
}
MyReturnObject
類包含一個通用對象,該對象可以包含我想要的任何對象。 在此示例中,我包括上面定義的InnerObject
類型,並且類型定義如下所示。
[KnownType(typeof(InnerObject))]
public class MyReturnObject {
public object Content { get; set; }
public MyReturnObject(object content) {
Content = content;
}
}
public class InnerObject {
public int Foo;
public string Bar;
// And some other properties
}
System.InvalidOperationException,mscorlib,版本= 4.0.0.0,文化=中性,PublicKeyToken = b77a5c561934e089
不應使用InnerObject類型。 使用XmlInclude或SoapInclude屬性可以指定靜態未知的類型。
您應該在wcf服務上使用[ServiceKnownType]
