    Why is this piece of code not working

    I have tried to look at it about 20 times but can't find any issue. Please bear in mind that I am a bit novice for c-sharp.

    The console part works fine so my StoreArray is not having any problem but there is no output to the file.

    string tempfilename = "F:\\Research\\Out_1_TickData.csv";
    outfileName = @tempfilename;
    StreamWriter outStream = new StreamWriter(outfileName, true);
                    for (int p = 0; p < Row_StoreArray; ++p)
                        for (int q = 0; q < Col_StoreArray; ++q )
                            Console.Write("," + StoreArray[p, q]);
                            outStream.Write("," + StoreArray[p, q] );
    Thanks in advance.

    First - it's hard to help you debug if we don't know what you're expecting and what behavior you are observing.

    General thoughts though:

    (1) Call StreamWriter.Close() afterward
    (2) What's with the @ in outfilename=@tempfilename. That is unusual syntax and probably unnecessary (to the extent that I wasn't even sure it was syntactically legal without checking).

    My preferred method of doing this is to buffer everything first and then do one disk IO event:

    System.Text.StringBuilder outData = new System.Text.StringBuilder();
    for(int p; ...)
        for(int q; ...)
            outData.Append("your data here");
        outData.AppendLine(); //New line at end of row
    System.IO.File.WriteAllText(outfileName, outData.ToString()); //Write to disk
    Best Regards,
