I'm trying to read .xlsx sheet in c# whose contents are spread over sheet. It's not a single table.Please look at the image http://i.stack.imgur.com/aaXxz.png[^].

I've highlighted the things which I want to read separately, in dataTables , if possible.
I've used Following code but it only works when there is only one table is present in the sheet.

Please help. Thanks.

What I have tried:

public DataSet ReadXlsx(string filepath)
{
    try
    {
        FileStream stream = File.Open(filepath, FileMode.Open, FileAccess.Read);

        //2. Reading from a OpenXml Excel file (2007 format; *.xlsx)
        IExcelDataReader excelReader2 = ExcelReaderFactory.CreateOpenXmlReader(stream);

        //...
        //4. DataSet - Create column names from first row
        excelReader2.IsFirstRowAsColumnNames = true;
        DataSet result2 = excelReader2.AsDataSet();

        return result2;
    }
    catch (Exception ex)
    {

        return null;
    }
}

What is ExcelReaderFactory?

Its a class from MetaData.
public static class ExcelReaderFactory
{
public static IExcelDataReader CreateBinaryReader(Stream fileStream);
public static IExcelDataReader CreateOpenXmlReader(Stream fileStream);
}

You get your code from exceldatareader.codeplex.com. if you get that component and want to complete your code based on that component you can continue like this:

You have your DataSet now, so continue reading it as you do with database results:

C#

            DataSet ds= ReadXlsx(filepath);

            string theOrder = ds.Tables[0].Rows[0][0].ToString();
            string theSite = ds.Tables[0].Rows[2][0].ToString();
            List<job> jobs= new List<job>();
            for (int i = 4; i < ds.Tables[0].Rows.Count; i++)
            {
                Job job=new Job();
                job.Number = ds.Tables[0].Rows[i][0];
                job.Facility = ds.Tables[0].Rows[i][1].ToString();
                job.Date = ds.Tables[0].Rows[i][2];
                job.TrackingNumber = ds.Tables[0].Rows[i][3];
                jobs.Add(job);
            }
