ColumnCount プロパティ (CalcReference)

セルまたは範囲参照の列数を取得します。

構文

Visual Basic
C#

'Declaration
 
Public MustOverride ReadOnly Property ColumnCount As Integer

'使用法
 
Dim instance As CalcReference
Dim value As Integer
 
value = instance.ColumnCount

public abstract int ColumnCount {get;}

プロパティ値

セルまたは範囲参照の列数を表すInteger

例

次のサンプルコードは、カスタム関数を作成します。
