实现

注解

此成员是显式接口成员的实现。This member is an explicit interface member implementation. 它只能在 Boolean 实例被强制转换为 IConvertible 接口时使用。It can be used only when the Boolean instance is cast to an IConvertible interface. 建议的替代Convert.ToSingle(Boolean)方法是调用方法。The recommended alternative is to call the Convert.ToSingle(Boolean) method.
