Question

好的，我已经找到了如何使用WCF使用Web服务。我正在使用XMLReader将XML数据读入变量。然后我使用服务方法调用来传递变量。但是，我收到警告说“检测到无法访问的代码”。我正在使用Visual Web Developer 2010 Express和C＃应用程序。

我希望变量可以在XMLreader切换案例之外访问。谁能告诉我怎么做？或者你能告诉我一个更好用的例子吗？我一直在寻找，但找不到一个很好的教程，将文件中的XML作为字符串与WCF消费相结合。谢谢！

                        lbNodes.Items.Add("TEST: " + FName + " " + LName);
                        string response;
                        response = serv.ImportLead(header, FName, LName, Email);

                        Label1.Text = response;

                        break;

                }

            }



        }
        reader.Close();

       //To DELETE the XML file after successful transmission uncomment the following line
        //File.Delete(path);

这已更新并正在运行。我现在收到用户名和密码不正确的回复。直到我从网络服务公司那里听到有关正确凭据的消息，我想我已经尽力了。

感谢您的建议！
