推荐答案

你想阻止这是不允许的输入或验证输入之前，它是可能的继续吗？

Do you want to prevent input that isn't allowed or validate the input before it is possible to proceed?

前者，当他们按下按键，但没有任何反应可能混淆用户。它通常是更好地展示自己的按键，但显示一个警告，当前的输入是无效的。这可能也是相当复杂设置掩蔽的电子邮件地址，例如正则表达式。

The former could confuse users when they press keys but nothing happens. It is usually better to show their keypresses but display a warning that the input is currently invalid. It's probably also quite complicated to set up for masking an email-address regular expression for example.

看的 ErrorProvider 以允许用户输入他们想要的东西，但显示警告信息，因为它们的类型。

Look at ErrorProvider to allow the user to type what they want but show warnings as they type.

有关您的一个文本框，只允许数字的第一个建议，你可能还需要考虑的的NumericUpDown 。

For your first suggestion of a text box that only allows numbers, you might also want to consider a NumericUpDown.
