Hi Guys,

I would like to inherited the MethodCls for both MasterPage and Page
But got the multiple base interface exception.

pubilc class MethodCls
{
}

public class Master:System.Web.UI.MasterPage,MethodCls
{
}

public class Page:System.Web.UI.Page,MethodCls
{
}


My Closest is solution is as follow. am I doing the correct way? or can
interface solve my issues as well?
cos I would like the MethodCls to reflect both Master and Page classes.

pubilc class MethodCls
{
}

public class Master:System.Web.UI.MasterPage
{
MethodCls _MethodCls=new MethodCls();

public MethodCls MyMethod
{
get{return _MethodCls;}
set {_MethodCls=value;}
}
}

public class Page:System.Web.UI.Page
{
MethodCls _MethodCls=new MethodCls();

public MethodCls MyMethod
{
get{return _MethodCls;}
set {_MethodCls=value;}
}
}


Best Regards.

Exception? Or compiler error? It should be the latter, and when you're
dealing with programmers being precise is important. :)
pubilc class MethodCls
{
}

public class Master:System.Web.UI.MasterPage,MethodCls
{
}

public class Page:System.Web.UI.Page,MethodCls
{
}

C# doesn't support multiple inheritance. You can only inherit one class.
However, you can inherit multiple interfaces so yes, using one or more
interfaces would be a way to address this. You can either declare a base
class that implements both interfaces, or you can declare two base classes
each of which provide the implementation for an interface and then use
composition in a new class to get the implementation from those classes
into a third class that implements both interfaces.
