私は昨日、いくつかの調査の結果、これに気付きましたが、それについて知っただけでは満足できませんでした. 誰かが私にこれを説明できますか？

これが私が経験していることです：

  • シリアル化の可能性が 2 つあります。
    • [System.CodeDom.Compiler.GeneratedCodeAttribute("System.ServiceModel", "4.0.0.0")]
    • [System.CodeDom.Compiler.GeneratedCodeAttribute("System.Runtime.Serialization", "4.0.0.0")]
  • Runtime.Serialization を含むシリアル化により、ArrayOf<T>コレクションが Web メソッドへのパラメーターとして期待される場合、エンティティが導入されます。
    • public void Foo(int[] ids) ==> public void Foo(int[] ids) System.ServiceModel
    • public void Foo(int[] ids) ==> public void Foo(ArrayOfInt ids) System.Runtime.Serialization
  • 選択されたシリアライゼーション エンジンは、抽象クラス型から派生する (または抽象クラス型である) パラメーターに依存します。
    • public void Bar(int[] ids) ==> System.Runtime.Serializationが使用されます。
    • public void Bar(DerivedFromAbstractClass baz, int[] ids) ==> System.ServiceModelが使用されます。

実行可能な例として:

public abstract class Foo { }

/// <summary>
/// Summary description for WebService1
/// </summary>
[System.Web.Services.WebService(Namespace = "http://tempuri.org/")]
[System.Web.Services.WebServiceBinding(ConformsTo = System.Web.Services.WsiProfiles.BasicProfile1_1)]
[System.ComponentModel.ToolboxItem(false)]
// To allow this Web Service to be called from script, using ASP.NET AJAX, uncomment the following line. 
// [System.Web.Script.Services.ScriptService]
public class WebService1 : System.Web.Services.WebService
{
    [System.Web.Services.WebMethod]
    public void HelloWorld(Foo foo, int[] ids)
    {
    }
}

私の .asmx ファイルは次のようになります。hello world が期待するパラメータの型に注意してください。ここで、サービス参照を生成します。

namespace CableSolve.Web.Api.Tests.ServiceReference1 {
    [System.CodeDom.Compiler.GeneratedCodeAttribute("System.ServiceModel", "4.0.0.0")]
    [System.ServiceModel.ServiceContractAttribute(ConfigurationName="ServiceReference1.WebService1Soap")]
    public interface WebService1Soap {

        [System.ServiceModel.OperationContractAttribute(Action="http://tempuri.org/HelloWorld", ReplyAction="*")]
        [System.ServiceModel.XmlSerializerFormatAttribute(SupportFaults=true)]
        void HelloWorld(CableSolve.Web.Api.Tests.ServiceReference1.Foo foo, int[] ids);
    }

    /// <remarks/>

    [System.Diagnostics.DebuggerStepThroughAttribute()]
    [System.ComponentModel.DesignerCategoryAttribute("code")]
    [System.Xml.Serialization.XmlTypeAttribute(Namespace="http://tempuri.org/")]
    public abstract partial class Foo : object, System.ComponentModel.INotifyPropertyChanged {

        public event System.ComponentModel.PropertyChangedEventHandler PropertyChanged;

        protected void RaisePropertyChanged(string propertyName) {
            System.ComponentModel.PropertyChangedEventHandler propertyChanged = this.PropertyChanged;
            if ((propertyChanged != null)) {
                propertyChanged(this, new System.ComponentModel.PropertyChangedEventArgs(propertyName));
            }
        }
    }

    [System.CodeDom.Compiler.GeneratedCodeAttribute("System.ServiceModel", "4.0.0.0")]
    public interface WebService1SoapChannel : CableSolve.Web.Api.Tests.ServiceReference1.WebService1Soap, System.ServiceModel.IClientChannel {
    }

    [System.Diagnostics.DebuggerStepThroughAttribute()]
    [System.CodeDom.Compiler.GeneratedCodeAttribute("System.ServiceModel", "4.0.0.0")]
    public partial class WebService1SoapClient : System.ServiceModel.ClientBase<CableSolve.Web.Api.Tests.ServiceReference1.WebService1Soap>, CableSolve.Web.Api.Tests.ServiceReference1.WebService1Soap {

        public WebService1SoapClient() {
        }

        public WebService1SoapClient(string endpointConfigurationName) : 
                base(endpointConfigurationName) {
        }

        public WebService1SoapClient(string endpointConfigurationName, string remoteAddress) : 
                base(endpointConfigurationName, remoteAddress) {
        }

        public WebService1SoapClient(string endpointConfigurationName, System.ServiceModel.EndpointAddress remoteAddress) : 
                base(endpointConfigurationName, remoteAddress) {
        }

        public WebService1SoapClient(System.ServiceModel.Channels.Binding binding, System.ServiceModel.EndpointAddress remoteAddress) : 
                base(binding, remoteAddress) {
        }

        public void HelloWorld(CableSolve.Web.Api.Tests.ServiceReference1.Foo foo, int[] ids) {
            base.Channel.HelloWorld(foo, ids);
        }
    }
}

ArrayOfInt がないことに注意してください。ここで、WebService1 から Foo パラメーターを削除し、2 番目のサービス参照を生成します。観察：

            CableSolve.Web.Api.Tests.ServiceReference2.HelloWorldRequest inValue = new CableSolve.Web.Api.Tests.ServiceReference2.HelloWorldRequest();
            inValue.Body = new CableSolve.Web.Api.Tests.ServiceReference2.HelloWorldRequestBody();
            inValue.Body.ids = ids;
            CableSolve.Web.Api.Tests.ServiceReference2.HelloWorldResponse retVal = ((CableSolve.Web.Api.Tests.ServiceReference2.WebService1Soap)(this)).HelloWorld(inValue);
        }
    }
}

一体何？HelloWorld の 2 番目のパラメーターの型の期待が、抽象クラスから派生した、または抽象クラスである別のパラメーターの存在に依存するのはなぜですか? HelloWorld に Foo パラメータなしで int[] ID のみを期待させることは可能ですが、ArrayOfInt を期待させることはできませんか?
