删除行会破坏合并的单元格

Question

我删除了某行，这行之后的合并单元格地址是错误的。例如，有合并单元格"A78:C78"。如果我这样做

worksheet.DeleteRow(5)

的地址

worksheet.Cells[77,1]

是"A77"。但是

worksheet.MergedCells[77,1]

为空，但应该是"A77:C77".

的地址

worksheet.Cells[78,1]

是"A78"。但是

worksheet.MergedCells[78,1]

是"A77:C77"，但应该为空。有趣和奇怪的是，在*.xlsx 中保存的文档中有合并单元格"A77:C77"。我不明白为什么会这样。也许有必要在删除合并单元格正确地址的行后以某种方式更新 sheet？

解决此问题的方法是在再次获取 mergedcell 地址之前保存文件，我在您提供的同一示例上尝试了以下代码，并且在 package.Save() 之后结果似乎是正确的。

 using (var package = new ExcelPackage(new System.IO.FileInfo(filePath)))
        {
            ExcelWorksheet worksheet = package.Workbook.Worksheets[1];
            var address = worksheet.Cells[78, 1];//address is "A78"
            var mergedadress = worksheet.MergedCells[78, 1];//address is "A78:C78"
            worksheet.DeleteRow(5);
            address = worksheet.Cells[77, 1];//address is "A77"
            mergedaddress = worksheet.MergedCells[77, 1];//null
            address = worksheet.Cells[78, 1];//address is "A78"
            mergedaddress = worksheet.MergedCells[78, 1];//address is"A77:C77"
            package.Save();
        }

 using (var package = new ExcelPackage(new System.IO.FileInfo(filePath)))
        {
            ExcelWorksheet worksheet = package.Workbook.Worksheets[1];
            var address = worksheet.Cells[77, 1];//address is "A77"
            var mergedaddress = worksheet.MergedCells[77, 1];//Address is "A77:C77"
            address = worksheet.Cells[78, 1];//address is "A78"
            mergedaddress = worksheet.MergedCells[78, 1];//null

            package.Save();
        }

我用过EPPLUS v4.1.1.0
