VSTO merged cells

Is there any way in VSTO (/JET OLEDB or other methods of reading excel files) to tell if the data comes from a single cell or merged range of cells and get this range ?

The shortest route here is to make use of the Boolean Range.MergeCells property.

Assuming that your cell reference were named myCell, you could use something like:

if (myCell.MergeCells)
{
    // The 'myCell' is part of a merged cell area.
}
Else
{
   // The 'myCell' is not part of any merged cell area.
}

You could also check the Cells.Count on the Range returned by the Range.MergeArea property:

if (myCell.MergeArea.Cells.Count > 1) {...}

or:

if (myCell.MergeArea.Count > 1) {...}

The last example works because the Range.Count property always returns the same value as does the Range.Cells.Count, by design.

Assuming the you use a method that can invoke & use the Excel object model, you check the MergeArea property of a cell to see if it contains anything other than that cell. If it does, then that cell is part of a MergeArea. Here's how I've done it in VBA:

IF CurrCell.MergeArea.Rows.Count > 1 Or CurrCell.MergeArea.Columns.Count > 1 Then
    'CurrCell is part of a MergeArea... '

The equivalent C# VSTO code should be fairly similar.
