# CellRange.ArrayFormula Property

Gets or sets the array formula associated with the cell or cell range.

## Declaration

``string ArrayFormula { get; set; }``
``Property ArrayFormula As String``

## Property Value

Type Description
String

A string that is the array formula.

## Remarks

An array formula is a special kind of formula used to perform calculations with arrays of cells. For detailed information, see the Array Formulas topic.

## Examples

This example demonstrates how to create an array formula.

##### NOTE

A complete sample project is available at https://github.com/DevExpress-Examples/winforms-spreadsheetcontrol-api-e4655

``````// Create an array formula that multiplies values contained in the cell range A2 through A11
// by the corresponding cells in the range B2 through B11,
// and displays the results in cells C2 through C11.
worksheet.Range.FromLTRB(2,1,2,10).ArrayFormula = "=A2:A11*B2:B11";

// Create an array formula that multiplies values contained in the cell range C2 through C11 by 2
// and displays the results in cells D2 through D11.
worksheet.Range["D2:D11"].ArrayFormula = "=C2:C11*2";

// Create an array formula that multiplies values contained in the cell range B2 through D11,
// adds the results, and displays the total sum in cell D12.
worksheet.Cells["D12"].ArrayFormula = "=SUM(B2:B11*C2:C11*D2:D11)";

// Re-dimension an array formula range:
// delete the array formula and create a new range with the same formula.
if (worksheet.Cells["C13"].HasArrayFormula) {
string af = worksheet.Cells["C13"].ArrayFormula;
worksheet.Cells["C13"].GetArrayFormulaRange().ArrayFormula = string.Empty;
worksheet.Range.FromLTRB(2,1,2,10).ArrayFormula = af;
}
