Problems returning array from a service

[Louisa55]

I've managed to write a service that returns an array in XML when tested by itself with no problems, but when I try and get my webpage to consume it I'm having difficulties

Here's my service simplified:

 public struct ListData
   {public string id, title, subtitle;}
 
[WebMethod]
   public ListData[] GetListData()
   {
      int x = 0;
      int number = 0;
      ListData[] List = null;
      List = new ListData[5];
 
      while (x < 5)
             {         
         List[x].id =  "subtitle test" + System.Convert.ToString(x);
         List[x].title =  "subtitle test" + System.Convert.ToString(x);
         List[x].subtitle = "subtitle test" + System.Convert.ToString(x);
         x++;
            }
 
      Return List;
   }

The consuming page has had countless versions of this:

 localhost.Service myws = new localhost.Service();
      localhost.ListData list = new localhost.ListData();
      list = myws.GetListData();
 
      Label1.Text = "Test data: <br/> " + list[0].Title + list[1].Subtitle + list[2].id;
 

I've tried so many combinations and Googled everywhere but I just can't seem to get it to work :(
I'm quite new at this so if anyone has any ideas I'd really appreciate it!

Exactly what difficulties are you having?

[Louisa55]

I can't seem to get the values into the "list" variable in the consuming website.
I keep getting errors like
"Cannot implicitly convert type 'localhost.ListData[]' to 'localhost.ListData'" or
"Cannot apply indexing with [] to an expression of type 'localhost.ListData'"
and seem to be getting nowhere

ok i see you have several small bugs here.

first thing you should see:

public ListData[] GetListData()

this method returns a an array of ListData objects. not a single ListData object
so the client app here:

list = myws.GetListData();

expects you to assign the returning array to an array of ListData.

so the solution to that would be:

localhost.ListData[] list;
list = myws.GetListData();

then i see you user different indexes to access info in the ListData Array

Label1.Text = "Test data: <br/> " + list[0].Title + list[1].Subtitle + list[2].id;

I assume u wish to access attributes of a single and same ListData object
so you should use it this way:

Label1.Text = "Test data: <br/> " + list[0].Title + list[0].Subtitle + list[0].id;

Hope this helps!

Thank you so much!
Yes you were right, it just wasn't declaring it as an array!

The random array values I was displaying were just so I could check I was using the array properly when reading into it from the database.

Again, thank you
