注解

类用于将ImageList的索引值与其他数据类型之间的转换 (通常String为)。 ImageIndexConverterThe ImageIndexConverter class is used to convert index values of an ImageList to and from other data types, typically String. 有关类型转换器的详细信息, 请参阅TypeConverter基类和如何:实现类型转换器For more information about type converters, see the TypeConverter base class and How to: Implement a Type Converter.

备注

通常, 您不会直接创建的实例ImageIndexConverterTypically, you do not directly create an instance of an ImageIndexConverter. 请改为TypeDescriptor调用GetConverter的方法。Instead, call the GetConverter method of TypeDescriptor. 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.
