Parameter.Clone Parameter.Clone Parameter.Clone Parameter.Clone Method

定義

傳回目前 Parameter 執行個體的複製。Returns a duplicate of the current Parameter instance.

protected:
 virtual System::Web::UI::WebControls::Parameter ^ Clone();
protected virtual System.Web.UI.WebControls.Parameter Clone ();
abstract member Clone : unit -> System.Web.UI.WebControls.Parameter
override this.Clone : unit -> System.Web.UI.WebControls.Parameter
Protected Overridable Function Clone () As Parameter

傳回

Parameter,為目前執行個體的完全複製。A Parameter that is an exact duplicate of the current one.

範例

下列程式碼範例示範如何從Parameter(Parameter) Parameter擴充類別的類別中呼叫此函式,以執行類別的正確物件複製行為。The following code example demonstrates how to call the Parameter(Parameter) constructor from a class that extends the Parameter class to implement correct object cloning behavior for the class. 這個程式碼範例是針對Parameter類別提供之較大範例的一部分。This code example is part of a larger example provided for the Parameter class.

// The StaticParameter copy constructor is provided to ensure that
// the state contained in the DataValue property is copied to new
// instances of the class.
protected StaticParameter(StaticParameter original) : base(original) {
  DataValue = original.DataValue;
}

// The Clone method is overridden to call the
// StaticParameter copy constructor, so that the data in
// the DataValue property is correctly transferred to the
// new instance of the StaticParameter.
protected override Parameter Clone() {
  return new StaticParameter(this);
}
' The StaticParameter copy constructor is provided to ensure that
' the state contained in the DataValue property is copied to new
' instances of the class.
Protected Sub New(original As StaticParameter)
   MyBase.New(original)
   DataValue = original.DataValue
End Sub

' The Clone method is overridden to call the
' StaticParameter copy constructor, so that the data in
' the DataValue property is correctly transferred to the
' new instance of the StaticParameter.
Protected Overrides Function Clone() As Parameter
   Return New StaticParameter(Me)
End Function

備註

方法會呼叫複製Parameter(Parameter)的函式,以使用目前實例的Parameter值來初始化類別的新實例。 CloneThe Clone method calls the Parameter(Parameter) copy constructor to initialize a new instance of the Parameter class with the values of the current instance.

如果您擴充Parameter類別,您可以覆Clone寫方法,以包含應該複製到衍生類別之新實例的任何狀態。If you extend the Parameter class, you can override the Clone method to include any state that should be copied to a new instance of your derived class.
