本菜初学mvc，有个问题想问一下？
Model：
public class User
{
public int Id{get;set;}
public string Name{get;set;}
public string Password{get;set;}
public UserRole Role{get;set;}
}
public class UserRole
{
public int Id{get;set;}
public string Name{get;set;}
}
public class AddUserViewModel
{
public string Name{get;set;}
public string Password{get;set;}
public UserRole Role{get;set;}//是这样还是：Public int RoleId{get;set;}?
}
