动态调用Web Service方法命名空间的问题
在网上找了段代码，实现动态调用Web Service方法，而不通过添加web引用的方法调用，代码是这样的


string @namespace = "EnterpriseServerBase.WebService.DynamicWebCalling" ;
            if((classname == null) ||(classname == ""))
             {
                 classname = WebServiceHelper.GetWsClassName(url) ;
             }

            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);
                 sdi.Import(cn ,ccu); 
                 CSharpCodeProvider csc          = new CSharpCodeProvider();
                 ICodeCompiler icc               = csc.CreateCompiler();
                
                //设定编译参数
                 CompilerParameters cplist       = new CompilerParamete
