Question

我删除了一行，并且在此行错误后删除了合并单元格的地址。例如，有合并的单元格＆＃34; A78：C78＆＃34;。如果我做

worksheet.DeleteRow(5)

的地址

worksheet.Cells[77,1]

是＆＃34; A77＆＃34;。但是

worksheet.MergedCells[77,1]

为null，但它应该是＆＃34; A77：C77＆＃34;。

的地址

worksheet.Cells[78,1]

是＆＃34; A78＆＃34;。但是

worksheet.MergedCells[78,1]

是＆＃34; A77：C77＆＃34;，但它应该为空。什么是有趣和奇怪的，有合并的细胞＆＃34; A77：C77＆＃34;在* .xlsx中保存的文档中。我无法理解为什么会这样。在删除合并单元格的正确地址的行之后，是否有必要以某种方式更新工作表？

重写此问题的解决方案是在再次获取mergedcell地址之前保存文件，我在您提供的相同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();
        }
