Write a program using LinQ with two lists - The first list contains Order Items while the second list contains Order Items count. The output is - order item with count

public static void LinqJoin()
{
IList orderItems = new List() {
new OrderItems(){orderId=1, orderName=”Soap”},
new OrderItems(){orderId=2, orderName=”Shampoo”},
new OrderItems(){orderId=3, orderName=”Moisturiser”}
};
IList orderCount = new List(){
new OrderCount(){orderId=1, count=3},
new OrderCount(){orderId=2, count=4},
new OrderCount(){orderId=3, count=8}
};
var joinResult= from items in orderItems
join oc in orderCount
on items.orderId equals oc.orderId
select new {
orderItem=items.orderName,
count= oc.count
} ;
foreach(var item in joinResult)
{
Console.WriteLine(item.orderItem + “ :”+ item.count);
}
}

public class OrderCount
{
    public int orderId { get; set; }
    public int count { get; set; }
}
public class OrderItems
{
    public int orderId{ get; set; }
    public string orderName{ get; set; }
}

See the below code:-

    class Order
    {
        public int Id;
        public string Name;
    }
    class OrderItem
    {
        public int Id;
        public string Name;
        public int OrderId;
    }
    public class Program
    {
        static void Main(string[] args)
        {
            var orders = new List<Order> {
                new Order { Id = 1,  Name = "One" } ,
                new Order { Id = 2,  Name = "Two" }
            };
            List<OrderItem> orderItems = new List<OrderItem>
            {
                new OrderItem { Id = 1, Name = "Item One", OrderId = 1 },
                new OrderItem { Id = 2, Name = "Item Two", OrderId = 1 },
                new OrderItem { Id = 3, Name = "Item Three", OrderId = 1 },
                new OrderItem { Id = 4, Name = "Item Four", OrderId = 2 },
                new OrderItem { Id = 5, Name = "Item Five", OrderId = 2 }
            };
            var results = from order in orders
                            join orderItem in orderItems on order.Id equals orderItem.OrderId into GroupOrderItems
                            select new { order, GroupOrderItems };
            //Just to write the results to the console
            string columns = "{0,-20} {1, -20}"; 
            Console.WriteLine(string.Format(columns, "Order", "Item Count"));
            foreach (var result in results)
            {
                Console.WriteLine(columns, result.order.Name, result.GroupOrderItems.Count());
            }
            Console.ReadLine();
        }
    }
