定義

取得控制項陣列中已指定索引的控制項。Gets the control for a specified index in a control array.

protected:
 System::Object ^ BaseGetItem(short Index);
protected object BaseGetItem (short Index);
member this.BaseGetItem : int16 -> obj
Protected Function BaseGetItem (Index As Short) As Object

參數

Index
Int16

整數,表示控制項陣列中控制項的索引。An integer that represents the index of the control in the control array.

傳回

所指定 Index 處的 ControlThe Control at the specified Index.

備註

對升級自 Visual Basic 6.0 之應用程式中使用的所有控制項陣列而言,BaseControlArray 是基底類別。The BaseControlArray class is the base class for all control arrays that are used in applications upgraded from Visual Basic 6.0. 由於通常不會使用此類別建立類別的執行個體,因此通常不會直接呼叫這個 Protected 方法,而是由衍生類別呼叫。Because this class is not typically used to create an instance of the class, this Protected method is usually not called directly but is instead called by a derived class.

注意

Microsoft.VisualBasic.Compatibility.VB6 命名空間中的函式和物件都是供這些工具使用,以便從 Visual Basic 6.0 升級至 Visual Basic。Functions and objects in the Microsoft.VisualBasic.Compatibility.VB6 namespace are provided for use by the tools for upgrading from Visual Basic 6.0 to Visual Basic. 在大多數情況下,這些函式和物件會複製在 .NET Framework.NET Framework 的其他命名空間中可以找到的功能。In most cases, these functions and objects duplicate functionality that you can find in other namespaces in the .NET Framework.NET Framework. 只有當 Visual Basic 6.0 程式碼模型與 .NET Framework.NET Framework 實作有顯著差異時,才需要這些項目。They are necessary only when the Visual Basic 6.0 code model differs significantly from the .NET Framework.NET Framework implementation.

給繼承者的注意事項

當您覆寫衍生類別中的 BaseGetItem 時,請勿呼叫基類的 BaseGetItem 方法。When you override BaseGetItem in a derived class, do not call the BaseGetItem method of the base class.
