NamedRange.FormulaArray Property
Gets or sets the array formula of the NamedRange control.
Namespace: Microsoft.Office.Tools.Excel
Assembly: Microsoft.Office.Tools.Excel (in Microsoft.Office.Tools.Excel.dll)
Syntax
'Declaration
Property FormulaArray As Object
Get
Set
Object FormulaArray { get; set; }
Property Value
Type: System.Object
The array formula of the NamedRange control.
Remarks
This property returns (or can be set to) a single formula or an array.
If the NamedRange control does not contain an array formula, this property returns nulla null reference (Nothing in Visual Basic).
If you use this property to enter an array formula, the formula must use the R1C1 reference style, not the A1 reference style.
Examples
The following code example creates a NamedRange and then uses the FormulaArray property to set the value of the NamedRange to equal the sum of the array of cells A1 through A3.
This example is for a document-level customization.
Private formualArrayRange As Microsoft.Office.Tools.Excel.NamedRange
Private Sub SetFormulaArray()
formualArrayRange = Me.Controls.AddNamedRange( _
Me.Range("B1"), "formualArrayRange")
Me.Range("A1", "A3").Value2 = 3333
Me.formualArrayRange.FormulaArray = "=Sum(R1C1:R3C1)"
End Sub
Microsoft.Office.Tools.Excel.NamedRange formualArrayRange;
private void SetFormulaArray()
{
formualArrayRange = this.Controls.AddNamedRange(
this.Range["B1", missing], "formualArrayRange");
this.Range["A1", "A3"].Value2 = 3333;
this.formualArrayRange.FormulaArray = "=Sum(R1C1:R3C1)";
}
