如何在C#中将Regex表达式设置为MaskedTextBox的掩码?

您可能应该只使用正则验证，而不是使用掩码，然后才可以直接使用正则表达式.确保(常规(未屏蔽)文本框)的CausesValidation属性为true，然后截取Validating事件，如果正则表达式不匹配，则将CancelEventArgs.Cancel设置为true.

Instead of using a mask, you should probably just use regular validation, and then you can use the regular expressions directly. Make sure that the CausesValidation property of the (regular, not masked) textbox is true, then intercept the Validating event and if the regular expression doesn't match, set the CancelEventArgs.Cancel to true.
