实体框架多对多关系

Question

I'm using the default ASP.NET profile and membership provider. I want to create a ASP List View with the name of the user and their role. When I try using this functionality I get a error:

Code behind:

public List<aspnet_Users> GetUsers(int startRowIndex, int maximumRows)
{
    this.entities.aspnet_Users.Include("aspnet_Roles").OrderBy(u => u.UserId).Skip(startRowIndex).Take(maximumRows).ToList();
}

Page directive:

<%# Eval("aspnet_Roles.RoleName")%>

It's not working because it's a many to many relationship in the database. How do I change my code behind method to map across the many to many relationship?

Answer 1

Don't do this. You shouldn't map the membership table s. The ASP.NET membership API already has a method to get a page of member data . You're reinventing the wheel, and replacing it with a version where you can't change the tire.
