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:

C#

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);

XML

[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; }

Solution 1

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

C#

proxy.getfeeds=ds;

It is the equivalent of writing

C#

Console.WriteLine = "hello";

can u tell me how to write and store ir in local system, even i checked my code using binding to gridview its working

OriginalGriff 9-Jan-12 5:58am

Without knowing your code (and I can't see more than you give us, remember) I would guess that you want to reverse the assignment:
proxy.getfeeds=ds;
becomes
ds = proxy.getfeeds();

my entire code is posted above,i want to save the results of webservice as xml in local system, i tried u r guess , one error,
cant implicitly convert wpfapplication.servicerefernce.arrayoffeeds to system.data.datset;

OriginalGriff 9-Jan-12 6:57am

That is because your getfeeds method returns a List, which you can't assign directly to a DataSet.
There is a Tip here: http://www.codeproject.com/Tips/226720/Converting-a-List-to-a-DataTable
Which will convert a list to a DataTable - you would then just have to add it to your DataSet with
ds.Tables.Add(myDataTable);
