Query an Array

Hello,

I need an app made in Visual Studio Basic doing a Windows Form Application. In the code also needs to be basic comments on what certain parts of the code are doing. The instructions of the app needing to be created is below.

Thank you in advance!

11.7 (Querying an Array of Invoice Objects) Use the class Invoice provided in the ex11_07 folder with this chapter’s examples to create an array
of Invoice objects. Use the sample data shown in Fig. 11.8 9. Class Invoice includes four properties—a PartNumber (type Integer), a
PartDescription (type String), a Quantity of the item being purchased (type Integer) and a Price (type Decimal). Write an app that performs
the following LINQ queries on the array of Invoice objects and displays the results:
a. Sort the Invoice objects by PartDescription
b. Sort the Invoice objects by Price
C. Select the PartDescription and Quantity and sort the results by Quantity
d. Select from each Invoice the PartDescription and the value of the Invoice (that is, Quantity *Price). Order the results by the value of
the invoice. Name the calculated column InvoiceTotal by using the expression
InvoiceTotal = item. Quantity * item.Price
where item is the name of the range variable in the LINQ query.
e. Using the results of the LINQ query in part (d), select the InvoiceTotals in the range $200 to $500.
