Question

所以我有一个像这样的for循环..：

for (int i = 12; i < 200; i++)
{
    //Console.WriteLine(Convert.ToString(sheet01.Cells[12, 2].Value2));
    if (!(string.IsNullOrEmpty(sheet01.Cells[i, 2].Value2)) && sheet01.Cells[i, 2].Value2.Length == 4)
    {
        Console.WriteLine(sheet01.Name);
        hcnNumber.Add(Convert.ToString(sheet01.Cells[i, 2].Value2));
    }
}

当我跨越多列时，只要单元格[i，2]，此代码就会遇到错误。

如何跳过跨越多列的行？

所以如果row.length＆gt; 1

我尝试在我的本地系统上处理您的要求。如果我理解您的要求，您只需要显示那些只有第一列有值的行，例如，如果一行有10列，其中包含全部或多于1列的数据，则需要跳过。我认为它可以帮助你实现目标。下面是循环的代码，为您提供预期的结果。

Excel.Application xlApp = new Excel.Application();
        Excel.Workbook xlWorkbook = xlApp.Workbooks.Open(@"C:\Users\acn\Desktop\CopyofFinancialSample.xlsx");
        Excel._Worksheet xlWorksheet = xlWorkbook.Sheets[1];
        Excel.Range xlRange = xlWorksheet.UsedRange;


        int rowCount = xlRange.Rows.Count;
        int colCount = xlRange.Columns.Count;

        for (int i = 1; i <= rowCount; i++)
        {
            int count = 0;
            for (int j = 1; j <= colCount; j++)
            {

                //add useful things here!   
                if (j != 1)
                {
                    if (xlRange.Cells[i, j] != null && xlRange.Cells[i, j].Value2 != null)
                    {
                        count++;
                    }
                }

            }
            if (count > 0)
            {

            }
            else
            {
                if (xlRange.Cells[i, 1] != null && xlRange.Cells[i, 1].Value2 != null)
                    Console.WriteLine(xlRange.Cells[i, 1].Value2.ToString() + "\t");
            }
        }

                }

            }
            if (count > 0)

                    Console.WriteLine(xlRange.Cells[i, 1].Value2.ToString() + "\t");
            }
        }
        //cleanup
        GC.Collect();
        GC.WaitForPendingFinalizers();

        //rule of thumb for releasing com objects:
        //  never use two dots, all COM objects must be referenced and released individually
        //  ex: [somthing].[something].[something] is bad

        //release com objects to fully kill excel process from running in the background
        Marshal.ReleaseComObject(xlRange);
        Marshal.ReleaseComObject(xlWorksheet);

        //close and release
        xlWorkbook.Close();
        Marshal.ReleaseComObject(xlWorkbook);

        //quit and release
        xlApp.Quit();
        Marshal.ReleaseComObject(xlApp);
         Console.ReadLine();

    }
