Question

我正在尝试读取/转换/解析为WebService调用的结果的字符串。

               WebMethod method = list.Services[0].Methods[0] as WebMethod;


    if(method != null) 
    {
                Object ResultsObj;
                ResultsObj = new Object();
                ResultsObj = method.Invoke();

                //Returns "WS.GeocodeResponse" needs to be inner values
                results = ResultsObj.ToString();

                //Like to do the following but get error: 
                   //'object' does not contain a definition for 'Results' and no extension
                     // method 'Results' accepting a first argument of type 'object' could be
                     // found (are you missing a using directive or an assembly reference?)
               results = ResultsObj.Results[0].ToString();

                //Or, do something like this but get same error
                results = String.Format("Latitude: {0}, Longitude: {1}",
                    ResultsObj.Results[0].Locations[0].Latitude,
                    ResultsObj.Results[0].Locations[0].Longitude);


                //Tried casting as an XmlDocument but get runtime error:
                //{"Unable to cast object of type 'WS.GeocodeResponse' to type 'System.Xml.XmlDocument'."}
                    XmlDocument doc = new XmlDocument();
                    doc = (XmlDocument) method.Invoke();
                    results = "do something with doc";

               //Tried looping through array of results but get error:
               // The type or namespace name 'WS' could not be found (are you missing a using directive or an assembly reference?)

               foreach(WS.GeocodeResult result in ResultsObj.GetType().Name)
                 {
                     continue;
                 }



              //Tried reverse engineering what Visual Studio does when create Web Reference
                //thanks to clue at http://www.west-wind.com/presentations/dotnetwebservices/DotNetWebServices.asp 
                        // “That's because the proxy object is actually compiled into the project 
                        //(take a look at \CodeClient\Web References\CodeWebService\CodeWebService.cs 
                        // to see the source for this 'phantom' object that VS generates for you and compiles into your application.”
                //Mine was "Project Name"/Web References/"Webservice Name"/Reference.cs  
                //I.E. ( LatLonVerification/Web References/net.virtualearth.dev/Reference.cs)
                // Renamed it and added "using LatLonVerification.VirtualEarthGeo;" reference to it in this class;
                //then finally tried to cast it to the new object type but got runtime error:
                //{"Unable to cast object of type 'WS.GeocodeResponse' to type 'LatLonVerification.VirtualEarthGeo.GeocodeResponse'."}  System.Exception {System.InvalidCastException}

               GeocodeResponse geocodeResponse = (GeocodeResponse) ResultsObj;
               results = "parse or do something with geocodeResponse";

背景：

我需要更新我们创建的LatLongVerification dll，以便通过com从MS Access调用Web服务。几个月前，它正在发挥作用。

然而，Bing Webservice发生了变化，我们的IT部门也陷入困境。防火墙改变了因此，在使用Web References方法更新Webservice之后，一切都有效，当离开公司网络但不在公司网络上时。 SoapUI测试工具也在防火墙后面保释。但是，开源Wizdl C＃.net工具确实可以在防火墙后面工作。

因此，这开始了对Wizdl工具（http://wizdl.codeplex.com/）进行逆向工程以作为dll而不是Windows窗体应用程序工作的目标。我认为各种各样的Access和Excel人也会喜欢。

当然，为了让它发挥作用，我已经硬编码了几个方面（稍后会修复）。到目前为止，我已成功将数据从Bing Webservice返回到一个对象，即使在网络上！然而，我似乎无法进行最终的转换或解析或转换，以便我可以将dll中的数据作为字符串输出。我是如此接近，因为我可以在本地调试器窗口中看到结果，但到目前为止它们是不可退还的。

不确定这是否相关，但是，当面对一个我无法直接开发的安全网络服务时，我使用了fiddler。

首先捕获wsdl文件（我想另一个），将它们保存为文本文件。然后，当视觉工作室在开发机器上进行服务更新时请求它们“备用”它们。

如何获取使用自定义代理进行Web服务请求的C＃Web Service调用的结果？
