I want to detect merged cells either in a row/entire sheet(preferable).Here is my code
Microsoft.Office.Interop.Excel.Application xl = new Microsoft.Office.Interop.Excel.Application();
Microsoft.Office.Interop.Excel.Workbook workbook = xl.Workbooks.Open(source);
//Microsoft.Office.Interop.Excel.Worksheet ws = (Microsoft.Office.Interop.Excel.Worksheet)workbook.Sheets[sheetNumber];
Microsoft.Office.Interop.Excel.Worksheet ws = (Microsoft.Office.Interop.Excel.Worksheet)workbook.Worksheets[objInMemory._sheetName];
xl.ScreenUpdating = false;
ws.Columns.ClearFormats();
ws.Rows.ClearFormats();
int colCount = ws.UsedRange.Columns.Count;
int rowCount = ws.UsedRange.Rows.Count;
int strtRow = ws.UsedRange.Rows[1].Row;
int strtCol = ws.UsedRange.Columns[1].Column;
Microsoft.Office.Interop.Excel.Range objRange = null;
Neither this piece of code
if (ws.Cells.MergeCells)
{
}
Nor this piece of code(only for row1)
for (int j = strtCol; j < strtCol + colCount; j++)
{
objRange = ws.Cells[strtRow, j];
if (ws.Cells[strtRow, j].MergeCells)
{
message = "The Sheet Contains Merged Cells";
break;
}
}
seem to work..Kindly let me know how to check if a sheet/specific range contains merged cells.
If you want to check if a Range contains merged cells, then the MergeCells property is what you're after.
If a range is merged, it will return true. If a range contains merged cells (i.e. some are merged, some aren't), it will return DBNull.Value.
So, this should work for your entire sheet:
object mergeCells = ws.UsedRange.MergeCells;
var containsMergedCells = mergeCells == DBNull.Value || (bool)mergeCells;
MergeCells is not a cells function, it's range function, so instead of:
if (ws.Cells[strtRow, j].MergeCells)
you need:
_Excel.Range range = (_Excel.Range) ws.Cells[strtRow, j];
if(range.MergeCells) //returns true if cell is merged or false if its not
Please remove ws.Columns.ClearFormats(); and ws.Rows.ClearFormats(); for the range.MergeCells property to work.
