Find and fix the bugs in a C# program

using System; /* Many businesses need to shipping costs for products they deliver. A customer usually gets a price break for more items ordered. Often, the prices for shipping are put into ranges of weights, only changing as a threshold is reached. Assume that a previous programmer wrote this code, but before debugging and delivering it, was transferred to a new department. Your task to finish the work. The code is almost correct, but compilation (syntax), coding (specification), or output (semantic) bugs exist. Carefully study the code, determine the problem, and fix the bug or bugs so that the output is as expected. Change as little code as possible to correct the problem.
