推荐答案

您的代码有无限循环.问题由以下块引起:

Your code has endless loop. The problem causes by this block:

while (letter != quit)
{

}

如果letter不等于quit，则此循环将永远不会结束.
您需要提供一个函数供用户修改letter并在新循环之前暂停循环.

If letter is not equal to quit, then this loop will never end.
You need to provide a function for user to modify letter and pause the loop before a new loop.

while (letter != quit)
{
    // Ask your question inside the loop
    Console.Clear();
    Console.WriteLine("what is your initial? Enter Z to quit");
    letter = Convert.ToChar(Console.ReadLine());

    // Process sales and commission calculation
    switch(letter)
    {
        case    ....
        case    ....
        case    ....
        default ....
    }

    // Display result message
    Console.WriteLine("bla bla bla...");

    // Pause the loop, enable user to read message
    Console.ReadKey();
}
