可以使用for循环。试试这个
bool _notempty = false;
for (int x = 1;x <= 15; x++)
{
if (currentWorkSheet.Cells[rowNumber, x].Value == null)
{
//MessageBox.Show("Error Message");
_notempty = false;
break;
}
else
{
_notempty = true;
}
}
您可以将列值放入对象数组或列表中，并测试它是否为null
// read each row from the start of the data (start row + 1 header row) to the end of the spreadsheet.
for (int rowNumber = startRow + 1; rowNumber <= currentWorkSheet.Dimension.End.Row; rowNumber++)
{
List<object> columns = List<object>();
columns.Add(currentWorkSheet.Cells[rowNumber, 1].Value);
columns.Add(currentWorkSheet.Cells[rowNumber, 2].Value);
columns.Add(currentWorkSheet.Cells[rowNumber, 3].Value);
columns.Add(currentWorkSheet.Cells[rowNumber, 4].Value);
columns.Add(currentWorkSheet.Cells[rowNumber, 5].Value);
columns.Add(currentWorkSheet.Cells[rowNumber, 6].Value);
columns.Add(currentWorkSheet.Cells[rowNumber, 7].Value);
columns.Add(currentWorkSheet.Cells[rowNumber, 8].Value);
columns.Add(currentWorkSheet.Cells[rowNumber, 9].Value);
columns.Add(currentWorkSheet.Cells[rowNumber, 10].Value);
columns.Add(currentWorkSheet.Cells[rowNumber, 11].Value);
columns.Add(currentWorkSheet.Cells[rowNumber, 12].Value);
columns.Add(currentWorkSheet.Cells[rowNumber, 13].Value);
columns.Add(currentWorkSheet.Cells[rowNumber, 14].Value);
columns.Add(currentWorkSheet.Cells[rowNumber, 15].Value);
if (!columns.Contains(null))
{
excelFileDataList.Add(new priceAddDelete
{
businessunitcode = columns[0].ToString(),
customerNumber = Convert.ToInt32(columns[1]),
productcode = columns[2].ToString(),
sizecode = columns[3].ToString(),
finishingmethodcode = columns[4].ToString(),
startdate = Convert.ToDateTime(columns[5]),
typeofprice = columns[6].ToString(),
pricetype = Convert.ToInt32(columns[7]),
typeofrent = Convert.ToInt32(columns[8]),
changesperweek = Convert.ToInt32(columns[9]),
adddelete = columns[10].ToString(),
price = Convert.ToInt32(columns[11]),
processed = Convert.ToInt32(columns[12]),
processed_date = Convert.ToDateTime(columns[13]),
systemuser_id = Convert.ToInt32(columns[14])
});

谢谢我的excelfiledatalist.Add现在将驻留在哪里？只需将它放在一个else语句中。我已经将它放在一个循环中，但没有显示它。你能现在检查一下我的更新代码吗。我不确定代码放在哪里。@user2320476请从代码中删除额外的缩进。这让我很难阅读。我现在开始尝试。对不起，这很有道理。我会继续，然后再打给你。谢谢@user2320476单独的问题，但我对此感兴趣。您使用什么工具加载/打开excel？它是开源的吗？我正在使用epplus加载excel文件。这将转到哪里？在循环中？对不起，在那里没有看到for循环。我已经编辑了我的答案。这行List columns=List；带来了一个错误。它说生成一个方法存根。它显示了一条扭曲的线条。需要在using语句中添加System.Collections.Generic。
