Linq to get values from 2 list with one unique Id

Question

I have one class to bind for ex.

public class MyClass
{
    public int Id { get; set; }
    public string Name { get; set; }
    public int Price { get; set; }
}

Now, this class will get values from different tables but they have common ID.

here is the Lists that I am getting in my loop.

var List1 = item.TicketTypes.Where(m => m.PerformanceID == item.Id)
                    .Select(t => new { t.Name, t.ID});

var List2 = item.Pricies.Where(m => m.PerformanceID == item.Id)
                    .Select(t => new { t.Price, t.ID });

item is object of for each loop instance.

What I want is,

I want List of MyClass filled with Entity Name and Price as per their ID.

Answer 1

There isn't much informations here for me to test this, but I have this to suggest:

// Make sure to add a constructor to MyClass
var List1 = item.TicketTypes.Where(m => m.PerformanceID == item.Id)
                            .Select(t => new MyClass(t.Name, t.ID, item.Pricies.FirstOrDefault(p => p.PerformanceID == t.ID).Price));

This should give you the desired result, but like I said I don't have enough informations to test this so make sure you comment the problems so we can fix them together.

Answer 2

In a Linq Statement, if my assumptions are right(cannot test it):

var result= from t1 in item.TicketTypes
            join t2 in item.Pricies on t1.ID equals t2.ID
            select new MyClass() { Id = t1.ID, Name = t1.Name, Price = t2.Price };

use .ToList() if you need a List

Answer 3

Try this :

var query = List1.Join(List2, l1 => l1.Id, l2 => l2.Id, (l1, l2) => new { ID = l1.Id, Name = l1.Name, Price = l2.Price });


foreach (var obj in query)
{
    Console.WriteLine("{0} - {1} - {2}", obj.ID, obj.Name, obj.Price);
}
