VBA LBound函數

LBound 函數

LBound函數返回指定數組中最小的下標。因此，陣列的LBound爲零。

語法:

LBound(ArrayName[,dimension])

1. ArrayName, 必需的參數。該參數對應於所述數組的名稱。

2. dimenstion, 一個可選的參數。這需要對應於所述陣列的維數的整數值。如果它是「1」，則它返回下界第一個的位置; 如果是「2」，則它返回下界第二位置等等。

例子 :

添加一個按鈕，並添加以下功能

Private Sub Constant_demo_Click() Dim arr(5) as Variant arr(0) = "1" 'Number as String
arr(1) = "VBScript 'String arr(2) = 100 'Number
arr(3) = 2.45 'Decimal Number arr(4) = #10/07/2013# 'Date arr(5) = #12.45 PM# 'Time msgbox("The smallest Subscript value of the given array is : " & LBound(arr)) ' For MultiDimension Arrays :
Dim arr2(3,2) as Variant
msgbox("The smallest Subscript of the first dimension of arr2 is : " & LBound(arr2,1))
msgbox("The smallest Subscript of the Second dimension of arr2 is : " & LBound(arr2,2))

End Sub

當執行函數輸出如下所示：

The smallest Subscript value of the given array is : 0
The smallest Subscript of the first dimension of arr2 is : 0
The smallest Subscript of the Second dimension of arr2 is : 0
