.NET interview questions: – Are there any readymade objects in .NET by which we can implement Lazy loading?

In .NET we have “Lazy<T>” class which provides automatic support for lazy loading. So let’s say if you want to implement “Lazy<>” in the above code we need to implement two steps for the same:-

Create the object of orders using the “Lazy” generic class.

private Lazy<List<Order>> _Orders= null;

Attach this Lazy<> object with the method which will help us load the order’s data.

_Orders = new Lazy<List<Order>>(() => LoadOrders());

Now as soon as any client makes a call to the “_Orders” object ,it will call the “LoadOrders” function to load the data.

You will get the “List<Orders>” data in the “Value” property.

public List<Order> Orders
{
   get
   {
      return _Orders.Value;
   }
}

Below goes the full code for the same.

public class Customer
{
private Lazy<List<Order>> _Orders= null;

        public List<Order> Orders
        {
            get
            {
               return _Orders.Value;
            }

       }
public Customer()
       {
       // Makes a database trip
       _CustomerName = “Shiv”;
       _Orders = new Lazy<List<Order>>(() => LoadOrders());

       }

 }
