Parameters

Name Type Description
reference String

A string that specifies the cell range reference in the A1 reference style.

Property Value

Type Description
CellRange

A CellRange object.

Remarks

Get the IRangeProvider object via the Worksheet.Range property and use the Item property to access a cell range object. Note that this property requires the cell range reference in the A1 reference style, regardless of which reference style is used in the workbook (DocumentSettings.R1C1ReferenceStyle). If you need to get a cell range by its R1C1 reference, use the IRangeProvider.Parse method.

To get a cell range by the indexes of the bounding rows and columns, use the IRangeProvider.FromLTRB method.
