Silverlight SLSvcUtil生成请求对象

我最近创建了一个WCF服务，并希望通过Silverlight应用程序使用它。为此，我使用SlSvcUtil（Silverlight 4）创建必要的客户端类。 但对于每个方法，该工具都会生成一个请求对象，该对象具有该方法通常采用的所有参数的属性

public System.IAsyncResult BeginDepartmentGetAll(DepartmentGetAllRequest request,    System.AsyncCallback callback, object asyncState)
    {
        object[] _args = new object[1];
        _args[0] = request;
        System.IAsyncResult _result = base.BeginInvoke("DepartmentGetAll", _args, callback, asyncState);
        return _result;
    }

public System.IAsyncResult BeginDummy(DummyRequest request, System.AsyncCallback callback, object asyncState)
    {
        object[] _args = new object[1];
        _args[0] = request;
        System.IAsyncResult _result = base.BeginInvoke("Dummy", _args, callback, asyncState);
        return _result;
    }

相应的请求类如下所示：

[System.Diagnostics.DebuggerStepThroughAttribute()]
[System.CodeDom.Compiler.GeneratedCodeAttribute("System.ServiceModel", "4.0.0.0")]
[System.ComponentModel.EditorBrowsableAttribute(System.ComponentModel.EditorBrowsableState.Advanced)]
[System.ServiceModel.MessageContractAttribute(WrapperName = "Dummy", WrapperNamespace ="http://example.com/Namespace", IsWrapped = true)]
public partial class DummyRequest

service.BeginMyMethod(id);

service.BeginMyMethod(new MyMethodRequest(id));

{

}

在类似的WCF项目中，这些方法采用Web服务方法的普通参数，而不使用请求对象。没有这些请求对象，我如何生成服务方法？

好的，我终于解决了这个难题：

slsvcutil是否生成这些神秘的请求对象取决于ServiceContractAttribute

如果设置：

[ServiceContract]
public interface MyService {
    [OperationContract]
    void MyMethod(Guid id);
}

[ServiceContract(Namespace = "http://example.com/MyService")]
public interface MyService {
    [OperationContract]
    void MyMethod(Guid id);
}

相应的客户端方法如下所示：

[System.Diagnostics.DebuggerStepThroughAttribute()]
[System.CodeDom.Compiler.GeneratedCodeAttribute("System.ServiceModel", "4.0.0.0")]
[System.ComponentModel.EditorBrowsableAttribute(System.ComponentModel.EditorBrowsableState.Advanced)]
[System.ServiceModel.MessageContractAttribute(WrapperName = "Dummy", WrapperNamespace ="http://example.com/Namespace", IsWrapped = true)]
public partial class DummyRequest

service.BeginMyMethod(id);

service.BeginMyMethod(new MyMethodRequest(id));

但如果您设置：

[ServiceContract]
public interface MyService {
    [OperationContract]
    void MyMethod(Guid id);
}

[ServiceContract(Namespace = "http://example.com/MyService")]
public interface MyService {
    [OperationContract]
    void MyMethod(Guid id);
}

看起来是这样的：

[System.Diagnostics.DebuggerStepThroughAttribute()]
[System.CodeDom.Compiler.GeneratedCodeAttribute("System.ServiceModel", "4.0.0.0")]
[System.ComponentModel.EditorBrowsableAttribute(System.ComponentModel.EditorBrowsableState.Advanced)]
[System.ServiceModel.MessageContractAttribute(WrapperName = "Dummy", WrapperNamespace ="http://example.com/Namespace", IsWrapped = true)]
public partial class DummyRequest

service.BeginMyMethod(id);

service.BeginMyMethod(new MyMethodRequest(id));
