Question

In an MVC project I have the following classes:

public abstract class Browse<T> where T : Browse<T>

public abstract class SqlBrowse<T> : Browse<T> where T : Browse<T>

public class SqlBrowseBoys : SqlBrowse<SqlBrowseBoys>
public class SqlBrowseGirls : SqlBrowse<SqlBrowseGirls>

and the following view model

public class BrowseViewModel
{
    public [INTERFACE] People { get; set; }
}

but I need an interface/class in the position labelled [INTERFACE] that can take both SqlBrowseBoys and SqlBrowseGirls so I can use BrowseViewModel in multiple places.

I’d love it if someone could show me how as my brain is now tied in knots. I suspect this will require some change(s) to the classes and that’s fine but I currently have no clue what that will be.

Many, many thanks.

Answer 1

Have SqlBrowse<T> implement a non-generic SqlBrowse interface (or abstract class), and then write

public SqlBrowse People { get; set; }

It’s hard to tell what changes that will entail to your classes because we don’t have their definitions.
