             }



            try

             {

                //获取WSDL

                 WebClient wc                   = new WebClient();

                 Stream stream                  = wc.OpenRead(url+"?WSDL");

                 ServiceDescription sd          = ServiceDescription.Read(stream);

                 ServiceDescriptionImporter sdi = new ServiceDescriptionImporter();

                 sdi.AddServiceDescription(sd,"","");

                 CodeNamespace cn                = new CodeNamespace(@namespace);

                

                //生成客户端代理类代码

                 CodeCompileUnit ccu             = new CodeCompileUnit();

                 ccu.Namespaces.Add(cn);

                //编译代理类

                 CompilerResults cr = icc.CompileAssemblyFromDom(cplist, ccu);

                if(true == cr.Errors.HasErrors)

                 {

                     System.Text.StringBuilder sb = new System.Text.StringBuilder();

                    foreach(System.CodeDom.Compiler.CompilerError ce in cr.Errors)

                     {

                         sb.Append(ce.ToString());

                         sb.Append(System.Environment.NewLine);

                     }

                    throw new Exception(sb.ToString());

                 }



                //生成代理实例，并调用方法

                 System.Reflection.Assembly assembly = cr.CompiledAssembly;

                 Type t = assembly.GetType(@namespace+"."+classname,true,true);

                object obj = Activator.CreateInstance(t);

                 System.Reflection.MethodInfo mi = t.GetMethod(methodname);



                return mi.Invoke(obj,args);

             }

            catch(Exception ex)

             {

                throw new Exception(ex.InnerException.Message,new Exception(ex.InnerException.StackTrace));

             }

         }



        private static string GetWsClassName(string wsUrl)

         {

            string[] parts = wsUrl.Split('/') ;

            string[] pps   = parts[parts.Length-1].Split('.') ;



            return pps[0] ;

         }

        #endregion

这段代码我用来动态访问c# 写的能。但是访问java提供的webservice的时候运行到57行： Type t = assembly.GetType(@namespace+"."+classname,true,true);
这里返回为空，所以就报错了。不知道什么原因。 java不存在命名空间问题。但是该如何获取type呢？或者用什么方式可以调用成功呢？希望帮忙解答谢谢
