注解

类的TypeValidationCompleted事件ValidatingType null是一个可选事件, 仅当属性显式设置为之外的类型时, 才引发此事件。 MaskedTextBoxThe TypeValidationCompleted event of the MaskedTextBox class is an optional event that is raised only if the ValidatingType property is explicitly set to a type other than null.

通常, 实现TypeValidationCompleted事件的处理程序以执行特定于掩码和类型的验证处理。Typically, a handler for the TypeValidationCompleted event is implemented to perform mask-specific and type-specific validation processing. 相反, 一般验证通常在Validating Control基类中定义的标准事件中执行。In contrast, general validation is typically performed in the standard Validating event defined in the Control base class.
