Copy range values in C#

B

Greetings,

There are several examples of what I am trying to do in this section but
they all appear to use VB. I have an Excel add-in written in C#. One thing
I need to do is copy the values from a range of cells into a different range
of cells in another workbook. Here is the code;


private void Go_Click(object sender, EventArgs e)
{
String strTopSourceCell = "A2", strBottomSourceCell = "A46";
String strTopDestinationCell = "F16", strBottomDestinationCell =
"F60";
Excel.Worksheet activeWorksheet =
(Excel.Worksheet)Globals.ThisAddIn.Application.ActiveSheet;
Excel.Range exrSource =
activeWorksheet.get_Range(strTopSourceCell, strBottomSourceCell);
Globals.ThisAddIn.ThisAddIn_OpenDigiKeyRFQTemplate();
activeWorksheet =
(Excel.Worksheet)Globals.ThisAddIn.Application.ActiveSheet;
Excel.Range exrDestination =
activeWorksheet.get_Range(strTopDestinationCell, strBottomDestinationCell);
//exrSource.Copy(exrDestination);
//exrSource.Copy();

exrSource.Copy(exrDestination.PasteSpecial(Microsoft.Office.Interop.Excel.XlPasteType.xlPasteValues,
Microsoft.Office.Interop.Excel.XlPasteSpecialOperation.xlPasteSpecialOperationNone, true, false));
}

When I use the (commented) line exrSrouce.Copy(exrDestination) I get the
values but the format of the destination is being altered.


When I use the (commented) line exrSrouce.Copy() I get a compiler error - no
overload for range.copy has zero arguments.

The documentation for Range.Copy() said that if the destination argument was
omitted it would copy to the clipboard. If I put null in there I get a run
time error.

I have tried using the Range.PasteSpecial as an argument for copy (the
uncommented line in my code) and it throws a runtime error. I suspect it is
to be used after the clipboard has been loaded.

How do I copy this range to the clipboard and then paste just the values to
the destination range (in C#).

Thanks for your help.

Hello Dale,

The PasteSpecial approach is right. Actually you are very close to the
solution now!

First, the Copy method can take zero arguments in VB because it supports
optional parameters, however this is not the story in C#. So we'll have to
pass in something. In this case, it would be Type.Missing.

And we need to specify correct parameters to the PasteSpecial method to
make it work.

I made a little bit changes to your code and please let me know if it works.

/* Begin code snippet */
String strTopSourceCell = "A2", strBottomSourceCell = "A46";
String strTopDestinationCell = "F16", strBottomDestinationCell = "F60";

Excel.Worksheet activeWorksheet =
(Excel.Worksheet)Globals.ThisAddIn.Application.ActiveSheet;

Excel.Range exrSource = activeWorksheet.get_Range(strTopSourceCell,
strBottomSourceCell);

Excel.Range exrDestination =
activeWorksheet.get_Range(strTopDestinationCell, strBottomDestinationCell);

exrSource.Copy(Type.Missing);
exrDestination.PasteSpecial(Microsoft.Office.Interop.Excel.XlPasteType.xlPas
teFormulas,

Microsoft.Office.Interop.Excel.XlPasteSpecialOperation.xlPasteSpecialOperati
onNone,
false,
false);
/* End code snippet */

Thank you so much. This resolved my issue. I did use

Microsoft.Office.Interop.Excel.XlPasteType.xlPasteValues

instead of

Microsoft.Office.Interop.Excel.XlPasteType.xlPasteFormulas

because all I want to copy is the current value in the cell.
