C# Program Question:

Create console application called CentennialFlowers.

You have been provided with:

• a content of Orders.cs file that contain the source code for the Orders class and Status enumeration.
• Content of Program.cs file that contains unfinished code.

You will have to complete 3 steps.

Step 1:

• Add the correct namespace so that JSON Serializer can work properly.

Step 2:

• Finish the SaveAllOrders method. This method is incomplete, and it should save the list of all orders from the parameter as a JSON file.
• Then close the file.

Step 3:

Implement the ReadPaidOrders method. There is very little code in this method, and you need to fully implement it to return the selected orders as a list. Below you can see the details of how this method should work:

• Read the list of orders from the JSON file saved by the SaveAllOrders method. Ensure to use the FILE_NAME constant for this.
• Loop through the orders;
• Select the orders that match the condition where the Status property is set to Paid.
• Populate the orders list.
• Close the file.

IMPORTANT: Dont modify that code in the Main() that has been provided. The output should match exactly the image below:

Once you are done, paste the code for each one of the steps in the box below. In the last test question, you will submit the whole solution with this and all other projects in this test.

Content of Orders.com:

using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Threading.Tasks; namespace CentennialFlowersJson { //order status enum enum Status { Paid, Unpaid, Cancelled } class Order { private int orderNumber; private string customerName; private string arrangement; private int quantity; private double unitPrice; private Status status; public int OrderNumber { get { return orderNumber; } set { orderNumber = value; } } public string CustomerName { get { return customerName; } set { customerName = value; } } public string Arrangement { get { return arrangement; } set { arrangement = value; } } public int Quantity { get { return quantity; } set { quantity = value; } } public double UnitPrice { get { return unitPrice; } set { unitPrice = value; } } public Status Status { get { return status; } set { status = value; } } public double TotalPrice { get { return quantity * unitPrice; } } public Order() { Quantity = 0; UnitPrice = 0; } } } Content of Program.cs:
