Is it possible to apply a Linq query from a HttpPostedFileWrapper?

My web app allows users to select a bunch of .csv files. I now need to open those files and import them.

My previous code, which uses paths and file names looks like;

            importedList = (from csvLine in File.ReadAllLines(fileName)
                            let x = csvLine.Split(',')
                            select new ImportedXDock
                            {
                                StoreNumber = int.Parse(x[0]),
                                DCNumber = int.Parse(x[1]),
                                DeliveryDay = x[2],
                                Activity = x[3],
                                ActivityDay = x[4],
                                Time = TimeSpan.Parse(x[5])

                            }).ToList();

However, now that i have a collection of HttpPostedFileWrapper objects how would I do the same?

edit

Or do I need to convert it to something and then read the file?

Solução

You may be able to loop over the file names instead of the input streams

foreach (var fileName in wrapper.Select(w => w.FileName))
{
    yield return (from csvLine in File.ReadAllLines(fileName)
                    let x = csvLine.Split(',')
                    select new ImportedXDock
                    {
                        StoreNumber = int.Parse(x[0]),
                        DCNumber = int.Parse(x[1]),
                        DeliveryDay = x[2],
                        Activity = x[3],
                        ActivityDay = x[4],
                        Time = TimeSpan.Parse(x[5])

                    }).ToList();
}
