Parameters
| Name | Type | Description |
|---|---|---|
| range | CellRange | A CellRange object specifying the cell range to clear. |
Remarks
The Clear method empties cells and clears all formatting. You can separately remove cell content, formatting, hyperlinks or comments using the Worksheet.ClearContents, Worksheet.ClearFormats, Worksheet.ClearHyperlinks or Worksheet.ClearComments methods, respectively.
To clear cells, you can also use the range’s Clear* extension methods, defined by the RangeExtensions class (RangeExtensions.Clear, RangeExtensions.ClearContents, RangeExtensions.ClearFormats, RangeExtensions.ClearHyperlinks and RangeExtensions.ClearComments). These extension methods are accessible as methods of the CellRange object and called by using the instance method syntax.
To delete entire cells from the worksheet, use the Worksheet.DeleteCells method (see the How to: Delete a Cell or Range of Cells example).
Example
This example demonstrates how to clear worksheet cells.
Clear All
To remove all cell information (content, formatting, hyperlinks and comments), call the
Worksheet.Clearmethod.Clear Cell Content
To remove cell content only (value and formula), call the Worksheet.ClearContents method, or assign the CellRange.Value property to null or to CellValue.Empty.
Clear Cell Formatting
To remove cell formatting only, call the Worksheet.ClearFormats method, or apply the Normal style to cells via the CellRange.Style property.
Clear Cell Hyperlinks
To remove any hyperlinks contained in a cell or cell range, call the Worksheet.ClearHyperlinks method. This method removes an active hyperlink from a cell, but leaves its descriptive text formatted as a hyperlink.
You can also get hyperlinks contained in the specified cell range via the HyperlinkCollection.GetHyperlinks method and remove them using the HyperlinkCollection.Remove method of the Worksheet.Hyperlinks collection. In this case, hyperlink text is left in the cell, but cell formatting is removed.
Clear Cell Comments
To remove any comments contained in a cell or cell range, call the Worksheet.ClearComments method, or remove comments from the worksheet’s Worksheet.Comments collection via the CommentCollection.Remove or CommentCollection.RemoveAt method.
// Remove all cell information (content, formatting, hyperlinks and comments).
worksheet.Clear(worksheet["C2:D2"]);
// Remove cell content.
worksheet.ClearContents(worksheet["C3"]);
worksheet["D3"].Value = null;
// Remove cell formatting.
worksheet.ClearFormats(worksheet["C4"]);
worksheet["D4"].Style = workbook.Styles.DefaultStyle;
// Remove hyperlinks from cells.
worksheet.ClearHyperlinks(worksheet["C5"]);
Hyperlink hyperlinkD5 = worksheet.Hyperlinks.GetHyperlinks(worksheet["D5"])[0];
worksheet.Hyperlinks.Remove(hyperlinkD5);
// Remove comments from cells.
worksheet.ClearComments(worksheet["C6"]);
