阅读Excel工作表时如何不跳过空行？

Question

I am using Microsoft.Office.Interop.Excel to read an Excel file.

The problem I am having is that when reading, it counts the first row that has information as row 1. So, if the first row to have information is row 3, it counts that as the first row. This is a problem because the Excel sheets sometimes have data on the first 2 rows, sometimes they don't. But the data I need to read always starts on the third row.

Here is the routine I am using to read the sheets:

Microsoft.Office.Interop.Excel.Application exl = new Microsoft.Office.Interop.Excel.Application();
        Workbooks wkbs = exl.Workbooks;
        Microsoft.Office.Interop.Excel.Workbook wkb = null;
        Sheets shts;
        Microsoft.Office.Interop.Excel.Worksheet wks = null;

        // load work book
        //wkb = wkbs.Open(races_data_path, 0, true, 5, "", "", true, Microsoft.Office.Interop.Excel.XlPlatform.xlWindows, "\t", false, false, 0, true, 1, 0);//oMissing
        wkb = wkbs.Open(races_data_path, Type.Missing, true, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing);//oMissing

        shts = wkb.Sheets;
        wks = (Microsoft.Office.Interop.Excel.Worksheet)shts.get_Item(Properties.Settings.Default.excel_worksheet);

        // read lines from worksheet
        Microsoft.Office.Interop.Excel.Range range = wks.UsedRange;

        for (int rCnt = 1; rCnt <= range.Rows.Count; rCnt++)
        {
            try
            {
                object[,] values = (object[,])range.Value2;

                if (Convert.ToString(values[rCnt, 4]) != "")
                {
                    //Console.WriteLine(String.Format("Ldd: {0} {1} {2}", Convert.ToInt16(values[rCnt, 2]), Convert.ToInt16(values[rCnt, 3]), Convert.ToString(values[rCnt, 4])));
                    if (races[Convert.ToInt16(values[rCnt, 1])] == null) races[Convert.ToInt16(values[rCnt, 1])] = new RaceObject();

                    races[Convert.ToInt16(values[rCnt, 1])].add_racer(Convert.ToInt16(values[rCnt, 2]), Convert.ToInt16(values[rCnt, 3]), Convert.ToString(values[rCnt, 4]), Convert.ToString(values[rCnt, 7]));
                }

            }
            catch (Exception ex)
            {
                data_loaded = false;
                rCnt = range.Rows.Count;
            }

        }

This example, you can see the loop count starts at '1'. This was for reading a sheet where the first 2 lines of the sheet were empty. If the first 2 lines have data, then this loop only works if I change the count start to '3'.

For example: The start value = 1 if the sheet looks like this:

no data
no data
has data
has data
has data

The start value = 3 if the sheet looks like this:

has unnecessary data
has unnecessary data
has data
has data
has data

Answer 1

Option 1: Add something to the first cell immediately before doing the rest: wks.cells(1, 1).value = "'" & wks.cells(1, 1).value This will extend the usedRange to the first cell.

Then the data will always start on the third row and you can easily always skip the first two rows.

Option 2: You can also use wks.UsedRange.Cells(1, 1).Row to see whether the first row is 1 or 3. Then you can adjust whether you use those rows or not.
