asp.net-mvc-3 - Data based on user role

Question

I have a product with array of prices. I want that based on the user group the corresponding price will be displayed.

As far i created roles that are describing these groups

1. Admin
2. UserPriceA
3. UserPriceB
4. UserPriceC

I would like somehow to get current users role.

Something like this:

public decimal Price {
    get
    {
        var price = Prices.First(p => p.PriceType.Name == Something.CurentUser.Role);
        return price; 
    }
}

Answer 1

You can write a conditional statement based on the name of each role. Based on if the user is a member of the role, execute a different LINQ statement.

if (User.IsInRole("Admin")) {
    // ...
}
else if (User.IsInRole("UserPriceA")) {
   // ...
}
else if (User.IsInRole("UserPriceB")) {
   // ...
}
else if (User.IsInRole("UserPriceC")) {
   // ...
}

Answer 2

You can't do it quite like that because a user can have multiple roles but you could do

Prices.Where( p=> Membership.GetRoles().Contains(p.PriceType.Name))
