This line works only for the DataGridView Control on Windows Forms:

DataObject dataObj = dataGridView1.GetClipboardContent();

This one addresses the same issue, but for the DataGrid control for the WPF Framework:

    private void copyDataGridContentToClipboard()
    {
        datagridGrupeProductie.SelectAll();
        datagridGrupeProductie.ClipboardCopyMode = DataGridClipboardCopyMode.IncludeHeader;

        ApplicationCommands.Copy.Execute(null, datagridGrupeProductie);
        datagridGrupeProductie.UnselectAll();
    }


    private void rightClickGrupeProductie_Click(object sender, RoutedEventArgs e)
    {
        copyDataGridContentToClipboard();
        Microsoft.Office.Interop.Excel.Application excelApp;
        Microsoft.Office.Interop.Excel.Workbook excelWkbk;
        Microsoft.Office.Interop.Excel.Worksheet excelWksht;
        object misValue = System.Reflection.Missing.Value;
        excelApp = new Microsoft.Office.Interop.Excel.Application();
        excelApp.Visible = true;
        excelWkbk = excelApp.Workbooks.Add(misValue);
        excelWksht = (Microsoft.Office.Interop.Excel.Worksheet)excelWkbk.Worksheets.get_Item(1);
        Microsoft.Office.Interop.Excel.Range CR = (Microsoft.Office.Interop.Excel.Range)excelWksht.Cells[1, 1];
        CR.Select();
        excelWksht.PasteSpecial(CR, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, true);
    }
