Make a Linq-to-SQL Generated User Class Inherit from MembershipUser

Question

I am currently building a custom Membership Provider for my Asp.net MVC website. I have an existing database with a Users table and I'm using Linq-to-Sql to automatically generates this class for me.

What I would like to do is have this generated User class inherit from the MembershipUser class so I can more easily use it in my custom Membership Provider in methods such as GetUser. I already have all the necessary columns in the table.

Is there any way to do this? Or am I going about this the completely wrong way?

Thanks!

Answer 1

Usually code generation tools creates so called partial classes, like:

public partial class User
{
    // class definition here
}

This means that you can extend definition of that class somewhere within the same namespace like that:

public partial class User: MembershipUser
{
    // if MembershipUser doesn't have parameterless constructor then you need
    // to add here one
}

And then you'll have User class inheriting from MembershipUser.

I have a similar problem.

linq has build a class user.

I made a custom class user:inheruser with one property to set.

how do I query user en cast it to inheruser.

When running I get an error "cannot convert user to inheruser"
