问题描述

当我尝试调用Web服务时，就像上面的错误一样，我想将返回结果odf Web服务另存为xml在本地系统中.我的代码是-

我的网络服务调用代码为:

When I am trying to call the webservice,it is saying like the above error, I want to save the return result odf webservice as xml in local system. My codes are -

My webservice calling code is:

DataSet ds = new DataSet();
       private void Window_Loaded(object sender, RoutedEventArgs e)
       {
           WpfApplication4.ServiceReference1.Service1SoapClient   proxy = new WpfApplication4.ServiceReference1.Service1SoapClient ();
           proxy.getfeeds=ds;

           ds.WriteXml(@"D:\satish\sab.xml", XmlWriteMode.WriteSchema);

我的网络服务代码是:

My webservice code is:

[WebMethod]
       public List<feeds> getfeeds()
       {
           List<feeds> feed = new List<feeds>();
           DataSet ds = new DataSet();
           ds.ReadXml(@"D:\satish1\na.xml");
           var query= from  item in ds.Tables[2].AsEnumerable()
                      select new feeds
                      {
                          titl=item.Field<string>("title"),
                          des=item.Field<string>("description")
                      };
           foreach (var s in query)
           {
               feed.Add(s);
           }
           return feed;
       }


   }
       public class feeds
       {
          public string titl { get; set; }
           public string des { get; set; }
       }

       }

推荐答案

错误消息非常具体-您正在尝试为方法名称分配一个值(方法组"位是因为所有具有相同名称的方法是允许重载的组)
当你写

The error message is quite specific - you are trying to assign a value to a method name (The "method group" bit is because all methods with the same name are a group to allow for overloading)
When you write

proxy.getfeeds=ds;

相当于写作

It is the equivalent of writing

Console.WriteLine = "hello";
