Hi Everyone,

How can I inherit an abstract class written in a web service class by a class within a project that referenced that web service?

EG:

Web Service Class

C#

[WebService(Namespace = "...")]
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
[System.ComponentModel.ToolboxItem(false)]
public class AppService : System.Web.Services.WebService
{
    public abstract class InheritMe<T>
    {
        ...
    }
}

Local Class

C#

class ConcreteClass : WebService.AppService.InheritMe<int>
{
    ...
}

Please, I really need help.
Thanks in advance..

Interesting question... I don't have the answer for now :)
I am hoping to have an idea why need to inherit the class from webservice.

Thanks for the reply. I have a generic data access class that can only be inherited. That's why I need an abstract class, but if it is a concrete class, how can I access it?

But why you need to inherit abstract class from web service? Don't you afford to make the same abstract class in the application where you are using your web service...

The abstract generic data access class has methods that connects to the database within the same server as the web service. It can also be done by making the data access class concrete and instantiate it in the local concrete class and create methods for each method of that data access class, I just want to inherit it so that it would be easier, but if there has no other option, how can I access a concrete class written inside a web service class?

oh so the reason why you need that is to call the method defined in your webservice? is that correct? coz i have a solution if that's the case.

Yes, but I need it to be generic because it defines an entity with a data type of T, or a defined data type, and I think changing it to a concrete class is hypothetically impossible(contradicting my comment here a while ago).

Thanks for the answer but my question is how to inherit an abstract class from a web service class, not from a class to the web service class, to the class within the project that referenced that web service. Your reply is highly appreciated though.

What's the problem?

If your abstract class is declared as the following:

C#

namespace MyWebServiceNamespace
{
    [WebService(Namespace = "http://tempuri.org/")]
    [WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
    [System.ComponentModel.ToolboxItem(false)]
    public class AppService : System.Web.Services.WebService
    {
        // ...

        public abstract class InheritMe<T>
        {
            // ...
        }

        // ...
    }
}

you can inherit it as the following:

C#

public class MyClass : MyWebServiceNamespace.AppService.InheritMe<int>
{
}

Because your class is declared in a WebService you also have to add a reference to System.Web.Services, in the project that contains the class that inherits your abstract class.
