用于 C++ 的通用 WebService (SOAP) 客户端库

E.g. This is the code to use the PeriodicTable web service:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Net;
using System.Web;
using System.Web.Services;
using System.Web.Services.Description;
using System.CodeDom;
using System.CodeDom.Compiler;
using System.Xml.Serialization;
using System.IO;
using System.Reflection;

namespace GenericSoapClient
{
class Program
    {
    static void method1()
        {
        Uri uri = new Uri("http://www.webservicex.net/periodictable.asmx?WSDL");
        WebRequest webRequest = WebRequest.Create(uri);
        System.IO.Stream requestStream = webRequest.GetResponse().GetResponseStream();

        // Get a WSDL
        ServiceDescription sd = ServiceDescription.Read(requestStream);
        string sdName = sd.Services[0].Name;

        // Initialize a service description servImport
        ServiceDescriptionImporter servImport = new ServiceDescriptionImporter();
        servImport.AddServiceDescription(sd, String.Empty, String.Empty);
        servImport.ProtocolName = "Soap";
        servImport.CodeGenerationOptions = CodeGenerationOptions.GenerateProperties;

        CodeNamespace nameSpace = new CodeNamespace();
        CodeCompileUnit codeCompileUnit = new CodeCompileUnit();
        codeCompileUnit.Namespaces.Add(nameSpace);

        // Set Warnings

        ServiceDescriptionImportWarnings warnings = servImport.Import(nameSpace, codeCompileUnit);

        if (warnings == 0)
            {
            StringWriter stringWriter =
                 new StringWriter(System.Globalization.CultureInfo.CurrentCulture);

            Microsoft.CSharp.CSharpCodeProvider prov =
              new Microsoft.CSharp.CSharpCodeProvider();

            prov.GenerateCodeFromNamespace(nameSpace,
               stringWriter,
               new CodeGeneratorOptions());

            string[] assemblyReferences =
               new string[2] { "System.Web.Services.dll", "System.Xml.dll" };

            CompilerParameters param = new CompilerParameters(assemblyReferences);

            param.GenerateExecutable = false;
            param.GenerateInMemory = true;
            param.TreatWarningsAsErrors = false;

            param.WarningLevel = 4;

            CompilerResults results = new CompilerResults(new TempFileCollection());
            results = prov.CompileAssemblyFromDom(param, codeCompileUnit);
            Assembly assembly = results.CompiledAssembly;
            Type service = assembly.GetType(sdName);

            //MethodInfo[] methodInfo = service.GetMethods();

            List<string> methods = new List<string>();

            // only find methods of this object type (the one we generated)
            // we don't want inherited members (this type inherited from SoapHttpClientProtocol)
            foreach (MethodInfo minfo in service.GetMethods(BindingFlags.Instance | BindingFlags.Public | BindingFlags.DeclaredOnly))
                {
                methods.Add(minfo.Name);
                Console.WriteLine (minfo.Name + " returns " + minfo.ReturnType.ToString());
                ParameterInfo[] parameters = minfo.GetParameters();
                foreach (ParameterInfo pinfo in parameters)
                    {
                        Console.WriteLine("   " + pinfo.Name + " " + pinfo.ParameterType.ToString());
                    }
                }

            // Create instance of created web service client proxy
            object obj = assembly.CreateInstance(sdName);

            Type type = obj.GetType();

            object[] args0 = new object[] { };
            string result0 = (string)type.InvokeMember(methods[0], BindingFlags.InvokeMethod, null, obj, args0);
            Console.WriteLine(result0);

            object[] args1 = new object[] { "Oxygen" };
            string result1 = (string)type.InvokeMember(methods[1], BindingFlags.InvokeMethod, null, obj, args1);
            Console.WriteLine(result1);
            }
        }
    }
}

在这段代码中，我明确使用了 methods[0] 和 methods[1] 但实际上你当然会检查方法名称.在这个例子中，我得到了元素周期表中所有元素的名称，然后得到了氧的原子量.
