BaseControlArray.LBound 方法

定義

傳回 Short,其中包含控制項陣列的最小可用註標。Returns a Short that contains the smallest available subscript for a control array.

public:
 short LBound();
public short LBound ();
member this.LBound : unit -> int16
Public Function LBound () As Short

傳回

Short,包含控制項陣列的下限。A Short that contains the lower bounds of a control array.

備註

LBound 函式會搭配 UBound 函數使用,以判斷控制項陣列的大小。The LBound function is used with the UBound function to determine the size of a control array.

BaseControlArray 類別是從 Visual Basic 6.0 升級之應用程式中所使用之所有控制項陣列的基類。The BaseControlArray class is the base class for all control arrays used in applications upgraded from Visual Basic 6.0.

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.
