示例1: SetAttribute
' The following class creates a custom ASP.NET server control that implements
' the IAttributeAccessor interface. It creates a MyTextBox class that contains
' Width and Text properties that get and set their values from view state.
' Pages that use this control create an instance of this control and set the
' Width property using the IAttributeAccessor.SetAttribute method.
' The page then displays the values of the Text and Width properties
' using the IAttributeAccessor.GetAttribute method.
' When compiled, this assembly is named MyAttributeAccessor.
