调用webservice而不添加webreference-具有复杂类型

我在用密码 This Site 动态调用WebService。

[SecurityPermissionAttribute(SecurityAction.Demand, Unrestricted = true)]
    public static object CallWebService(string webServiceAsmxUrl, string serviceName, string methodName, object[] args)
    {
        System.Net.WebClient client = new System.Net.WebClient();
        //-Connect To the web service
        using (System.IO.Stream stream = client.OpenRead(webServiceAsmxUrl + "?wsdl"))
        {
            //--Now read the WSDL file describing a service.
            ServiceDescription description = ServiceDescription.Read(stream);
            ///// LOAD THE DOM /////////
            //--Initialize a service description importer.
            ServiceDescriptionImporter importer = new ServiceDescriptionImporter();
            importer.ProtocolName = "Soap12"; // Use SOAP 1.2.
            importer.AddServiceDescription(description, null, null);
            //--Generate a proxy client. importer.Style = ServiceDescriptionImportStyle.Client;
            //--Generate properties to represent primitive values.
            importer.CodeGenerationOptions = System.Xml.Serialization.CodeGenerationOptions.GenerateProperties;
            //--Initialize a Code-DOM tree into which we will import the service.
            CodeNamespace nmspace = new CodeNamespace();
            CodeCompileUnit unit1 = new CodeCompileUnit();
            unit1.Namespaces.Add(nmspace);
            //--Import the service into the Code-DOM tree. This creates proxy code
            //--that uses the service.
            ServiceDescriptionImportWarnings warning = importer.Import(nmspace, unit1);
            if (warning == 0) //--If zero then we are good to go
            {
                //--Generate the proxy code 
                CodeDomProvider provider1 = CodeDomProvider.CreateProvider("CSharp");
                //--Compile the assembly proxy with the appropriate references
                string[] assemblyReferences = new string[5] { "System.dll", "System.Web.Services.dll", "System.Web.dll", "System.Xml.dll", "System.Data.dll" };
                CompilerParameters parms = new CompilerParameters(assemblyReferences);
                CompilerResults results = provider1.CompileAssemblyFromDom(parms, unit1);
                //-Check For Errors
                if (results.Errors.Count > 0)
                {
                    StringBuilder sb = new StringBuilder();
                    foreach (CompilerError oops in results.Errors)
                    {
                        sb.AppendLine("========Compiler error============");
                        sb.AppendLine(oops.ErrorText);
                    }
                    throw new System.ApplicationException("Compile Error Occured calling webservice. " + sb.ToString());
                }
                //--Finally, Invoke the web service method 
                Type foundType = null;
                Type[] types = results.CompiledAssembly.GetTypes();
                foreach (Type type in types)
                {
                    if (type.BaseType == typeof(System.Web.Services.Protocols.SoapHttpClientProtocol))
                    {
                        Console.WriteLine(type.ToString());
                        foundType = type;
                    }
                }

                object wsvcClass = results.CompiledAssembly.CreateInstance(foundType.ToString());
                MethodInfo mi = wsvcClass.GetType().GetMethod(methodName);
                return mi.Invoke(wsvcClass, args);
            }
            else
            {
                return null;
            }
        }
    }

当我使用内置类型时,这很好,但是对于我自己的类,我得到:

这些类引用同一程序集和同一版本。在生成临时程序集时,是否需要将程序集作为参考?如果是这样,怎么办?

谢谢。

更新

似乎最好的解决方案是构建一个可以映射 AssemblyX.MyCustomType 相当于 GeneratedAssembly.MyCustomType .

在我的例子中, MyCustomType 包含更多类型(这些类型都应该是生成的程序集的一部分),因此似乎我需要一个方法来执行此“深度复制”。另外,tdxdatatypes.agencyoutput的一些属性是其他类的数组,只是为了让事情更有趣…

我创造了一个 new question 为了地图。
