2,880 Pointsusing System.Collections.Generic;
using System.Data.Entity;
using System.Linq;
namespace Treehouse.CodeChallenges
{
public static class Repository
{
public static List<Course> GetCourses()
{
//Instantiate an instance of the Context class within a using statement
using(var context = new Context())
{
// Return the results of calling ToList on the context's Courses DbSet property
return context.Courses.ToList();
}
}
}
}
Let's dissect the code and see what we are doing. We instantiate an instance of the Context class by writing:
var context = new Context()
and given the new instance variable the name "context".
Now, based on the Code Challenge description, we know that the context instance should have a Courses DbSet property. So, we can access the property by writing:
context.Courses
Then, the Code Challenge description told us that we need to call ToList on the property. So, we call the ToList function by:
context.Courses.ToList()
The very last step is to return the result. We can do so by using the return statement:
return context.Courses.ToList();
