Excel SpecialCells（xlCellTypeBlanks）合并单元格失败

Question

Excel SpecialCells(xlCellTypeBlank) includes all cells in a merged range, regardless of whether they are blank. I consider this to be a bug, and I desperately need a workaround. Steps to duplicate:

(1) Create a worksheet with some text in cells A1 and B3. Now activesheet.usedrange.cells.count = 6 and activesheet.usedrange.specialcells(xlcelltypeblanks).cells.count = 4 These values are as expected.

(2) Now merge cells A1:A2, and activesheet.usedrange.cells.count = 6 and activesheet.usedrange.specialcells(xlcelltypeblanks).cells.count = 5 Both A1 and A2 are now considered blank.

I need to find a way to select just cells A3, B1, and B2 in this case. I'm actually doing this using .NET Excel Interop, so I do not want to have to actually retrieve the cell value as a part of the test, since this is a huge performance penalty in Excel Interop; so I'm restricted to an internal cell selection function such as SpecialCells.

I got this to work by selecting smaller ranges at various places in the code, usually just before doing any cell merging. I consider this to be a workaround, not really a solution. Thanks to those who commented - you helped inspire this workaround.
