Design a Windows Form C program for a car sale Assuming ther

Design a Windows Form C# program for a car sale. Assuming there are only a few car models (3 to 5).  

(1) Prepare a text file to be read into the program for car information: Car model name, Car price, and Car image file name. Prepare also the car image files. Allow the choice of one of the cars to display its name, its price, and its image.

(2) Read in the OhioSalesTaxRates.txt file and allow the choice of one of the counties for a corresponding sale tax rate.

(3) Show the selected car model, car image, car price, tax rate, tax, and total price.
