注解

SelectionRange类表示单个日期或日期范围。The SelectionRange class represents a single date or a range of dates. 此类通常与MonthCalendar控件相关联, 它表示所选日期和突出显示日期。This class is commonly associated with the MonthCalendar control, where it represents the selected and highlighted dates. 类是SelectionRange的附属类, 使你能够与其他类型 (最常见的字符串) 相互转换。 SelectionRangeConverterThe SelectionRangeConverter class is an adjunct class to SelectionRange that enables you to convert to and from other types, most often strings.

有关类型转换器的详细信息, 请参阅TypeConverter基类、通用化类型转换如何:实现类型转换器For more information about type converters, see the TypeConverter base class, Generalized Type Conversion, and How to: Implement a Type Converter.

备注

永远不应创建SelectionRangeConverterYou should never create a SelectionRangeConverter. 而应调用 GetConverter 类的 TypeDescriptor 方法。Instead, call the GetConverter method of the TypeDescriptor class. 有关详细信息, 请参阅TypeConverter基类中的示例。For more information, see the examples in the TypeConverter base class.
