Question about class definition

09-22-2009 10:25 AM |

Hi,

I have a weproject, a silverlight application and a silverlight class library. In the class library I have a class (name: variables), which had some properties and methods and which I like to use in the webproject and in the silverlight application.

Now I use the class "variables" in my webprojekt in an webservice (Webmethod) as a Parameter.

[WebMethod]

public byte[] CreatebyteArray(Variables _variables)

{

}

But when I create a new instance of the class "variables" in my silverlight application, where I create a proxy of the webservice, I only see the properties of the class and don't the methods.

Do you have any idea, why it is so?

Best Regards

Malone

Hi,

unfortunately I can't test your code, but with your code I can use my class "variables" from my class library in both projects......webproject and silverlight application?

 Hi,

You Paste the xaml.cs code so that we'll be able to help you.

And i would also suggest you to use WCF services rather than the asmx ones for better performance and also various advantages.

I have a class in my class library:

public class Variables

{

       private List<Variables> listvalues = new List<Variables>();

       // Properties and Methods for e.g.

        public void _AddVariable(string _fieldname, string _fieldstringvalue)
        {
            listvalues.Add(new Variables(_fieldname, _fieldstringvalue));
        }

}

I use this class in my webproject in an webservice:

[WebMethod]
public byte[] CreatebyteArray(Variables _variables)
{

    // Here I go per foreach through "_variables", which contains a List

}

Now, I would like to use the class in my silverlight application:

    public partial class viewPage : UserControl
    {
        // Proxys
        myProxy.VariablesServiceSoapClient variablesproxy;

        public viewPage ()
        {
            // Required to initialize variables
            InitializeComponent();

            this.Loaded += new RoutedEventHandler(vwUntwPruefungsergebnis_Loaded);
        }

        private void viewPage _Loaded(object sender, RoutedEventArgs e)
        {
            Variables listvariables = new Variables();
            listvariables._AddVariable("Test", "Test"); // This Method is not available.....only the properties of the class!!!

            variablesproxy= new myProxy.VariablesServiceSoapClient ("VariablesServiceSoap", Globals.WebRootPath + @"Services/Variables/VariablesService.asmx");
            variablesproxy.CreatebyteArrayCompleted += new EventHandler<CreatebyteArrayCompletedEventArgs>(variablesproxy_CreatebyteArrayCompleted);
            variablesproxy.CreatebyteArrayAsync(listvariables);
        }

     private void variablesproxy_CreatebyteArrayCompleted(object sender, myProxy.CreatebyteArrayCompletedEventArgs e)
     {
            byte[] bytearray= e.Result;
     } 

}

My "Variables" class has the reference to my "variablesproxy" and I can't see the methods of my class in intellisense. When the class "Variables" has the reference to my silverlight class library, then I can see the methods, but then I get an error, that the class has two references or it exist an ambivalent reference. I hope you know, what I mean!

This might help:

If I understand you right you'll need three solutions:
1)  Your webservice solution - this refers to the dll produced by 3.A
2)  Your silverlight solution - this refers to the dll produced by 3.B
3)   A solution that that has two projects:
     A)  project 1 with the file that holds your class and that compiles for the non-silverlight clr used by your webservice.
     B)  project 2 with the file that holds your class and that compiles for the silverlight clr

Sorry for late reply. I was busy yesterday and couldn't able to check the forum yesterday.  

Malone:

listvariables._AddVariable("Test", "Test"); // This Method is not available.....only the properties of the class!!!

Yes. It's because this method is not generated in proxy class (Reference.cs).

I think you will have to share the linked class betwen Silverlight class library and .NET class library and use the Channel Factory to invoke. Please wait.

I can't really follow you. I hope you maybe have a code snippet for me! 

And a big "Thank you" to all, who have answered me so far.

Hey Malone,

Sorry about that. I was away from forum since I was too busy in new office. :(

Did you manage to solve your problem?
