是什么让您认为它有问题?我们看不懂您的想法，或者您的
电脑的屏幕.因此，您将需要付出更多的努力来实现
告诉我们发生了什么事.

如果您在一个TextBoxes包含非数字时遇到异常
字符或为空，然后切换为使用TryParse而不是Convert.

What makes you think it has a problem? We can't read your mind, or your
computer's screen. So you're going to have to make more of an effort to
tell us what's happening.

If you're getting an exception when one of the TextBoxes has non-numeric
characters or is empty, then switch to using TryParse instead of Convert.
