備註

LowerCaseStringConverter類別可讓物件轉換成小寫字串。The LowerCaseStringConverter class allows an object to be converted to a lowercase string. 這個類別也會提供支援, 以確認物件類型可以在進行轉換之前, 轉換成小寫字串。This class also provides support to verify that an object type can be converted to a lowercase string before the conversion is made.

的方法LowerCaseStringConverter會將執行ITypeDescriptorContext介面的物件當做參數。The methods of LowerCaseStringConverter take as a parameter an object that implements the ITypeDescriptorContext interface. 此介面提供元件的相關內容資訊。This interface provides contextual information about a component. 一般而言, 此介面會在設計階段用來提供設計階段容器的相關資訊。Typically, this interface is used at design time to provide information about a design-time container. ITypeDescriptorContext通常用於類型轉換中。The ITypeDescriptorContext is commonly used in type conversion.
