NamedRangeCollectionAdd Method (String, CellRange) |

Adds a new named range. Named ranges are used to represent cells, ranges of cells,
formulas or constant values.

**Namespace:**
GemBox.Spreadsheet
**Assembly:**
GemBox.Spreadsheet (in GemBox.Spreadsheet.dll) Version: 41.3.30.1070

Syntax public void Add(
string name,
CellRange range
)

Public Sub Add (
name As String,
range As CellRange
)

#### Parameters

- name
- Type: SystemString

The user-defined name. - range
- Type: GemBox.SpreadsheetCellRange

The range to be referred by name.

Remarks
You can use the labels of columns and rows on a worksheet to refer to the cells within
those columns and rows. Or you can create descriptive names to represent cells, ranges of cells,
formulas, or constant values. Labels can be used in formulas that refer to data on the same
worksheet; if you want to represent a range on another worksheet, use a name.
You can also create 3-D names that represent the same cell or range of cells across multiple worksheets.

Examples
Following code demonstrates how to use formulas and named ranges. It shows next features:
cell references (both absolute and relative), unary and binary operators, constant operands (integer and floating point),
functions and named cell ranges. At the end, code shows how to calculate worksheet formulas.

ws.Cells["A1"].Value = 5;
ws.Cells["A2"].Value = 6;
ws.Cells["A3"].Value = 10;
ws.Cells["C1"].Formula = "=A1+A2";
ws.Cells["C2"].Formula = "=$A$1-A3";
ws.Cells["C3"].Formula = "=COUNT(A1:A3)";
ws.Cells["C4"].Formula = "=AVERAGE($A$1:$A$3)";
ws.Cells["C5"].Formula = "=SUM(A1:A3,2,3)";
ws.Cells["C7"].Formula = "= 123 - (-(-(23.5)))";
ws.NamedRanges.Add("DataRange", ws.Cells.GetSubrange("A1", "A3"));
ws.Cells["C8"].Formula = "=MAX(DataRange)";
CellRange cr = ws.Cells.GetSubrange("B9", "C10");
cr.Merged = true;
cr.Formula = "=A1*25";
ws.Calculate();

ws.Cells("A1").Value = 5
ws.Cells("A2").Value = 6
ws.Cells("A3").Value = 10
ws.Cells("C1").Formula = "=A1+A2"
ws.Cells("C2").Formula = "=$A$1-A3"
ws.Cells("C3").Formula = "=COUNT(A1:A3)"
ws.Cells("C4").Formula = "=AVERAGE($A$1:$A$3)"
ws.Cells("C5").Formula = "=SUM(A1:A3,2,3)"
ws.Cells("C7").Formula = "= 123 - (-(-(23.5)))"
ws.NamedRanges.Add("DataRange", ws.Cells.GetSubrange("A1", "A3"))
ws.Cells("C8").Formula = "=MAX(DataRange)"
Dim cr As CellRange = ws.Cells.GetSubrange("B9", "C10")
cr.Merged = True
cr.Formula = "=A1*25"
ws.Calculate()
