Question

Im getting this error. Even though i already created a folder “CMSExportedData”
Could not find a part of the path ‘C:\CMSExportedData\Sales-20\07\2012.txt’.

Kindly help please

using (FileStream fs = new FileStream("C:\\CMSExportedData\\Sales-" + DateTime.Now.ToString("dd/MM/yyyy") + ".txt", FileMode.Create))
{
    using (StreamWriter sw = new StreamWriter(fs, Encoding.Default))
    {
        //use stream
    }
}

You’re formatting the date as part of the filename in such a way that the date separators are slashes, which get converted to backslashes (path separators) by the path logic:

‘C:\CMSExportedData\Sales-20\07\2012.txt’.

There’s no Sales-20 folder, and no 07 folder.

Solution: don’t use path separator characters in your file names :). This solution also formats the date as year-month-day because that makes the file names sort in chronological order:

"C:\\CMSExportedData\\Sales-" + DateTime.Now.ToString("yyyyMMdd") + ".txt"
