Saving a file with the datetime in the file name

Question

See more:

I am writing a file to a specific location with the datetime included in the file name. After the file is written, I am needing to prompt a save as box to the user. However, when the program tries to find the newly created file, it is unable to because the datetimes do not match.

I know why it is doing that, I just can't figure out how get around it. I have tried using variables but just can't seem to get it right.

Thank you in advance for any advice or examples.

C#

if (dr[12].ToString().Contains("99|"))
                            {
                                StreamWriter sw = new StreamWriter(@"C:\inetpub\temp\99-Authorize.Net - " + date1 + " @ " + date2 + ".ach");//
                                if (dr[0].ToString() != "2")
                                {
                                    if (dr[9].ToString() != "Total Amount")
                                    {
                                        sw.Write("6                            ");
                                        sw.Write(dr[9].ToString().Replace(".", "").Replace(",", "").PadLeft(10, '0'));
                                        sw.Write((dr[12].ToString()).PadRight(15, ' '));
                                        sw.Write((dr[13].ToString() + " " + dr[14].ToString()).PadRight(40));
                                        sw.Write(sw.NewLine);
                                    }
                                }
                                sw.Write("9");
                                sw.Write(sw.NewLine);
                                sw.Close();

C#

string fileName2 = ("99-Authorize.Net - " + date1 + " @ " + date2 + ".ach");//
        string filePath2 = (@"C:\inetpub\temp\99-Authorize.Net" + date1 + " @ " + date2 + ".ach");

        Response.Clear();
        Response.AppendHeader("content-disposition",
        "attachment; filename=" + fileName2);
        Response.ContentType = "application/octet-stream";
        Response.WriteFile(filePath2);
        Response.Flush();
        Response.End();

Solution 1

Perhaps you could store the file name in a session variable and pass that along.

Something like:

C#

string filename = "99-Authorize.Net - " + date1 + " @ " + date2 + ".ach";
Session.Add("DatedFileName", filename);

You could then use this with:

C#

filename = Session("DateFileName");

Very simplistic but might suit your need.

Thank you, that is what I was trying to do!

Depending oh the culture, the DateTime.ToString can be conflicting for a file name. You may use string filename = string.Format( "99-Authorize.Net - {0} @ {1}", date1.ToString( "yyyyMMddHHmmss" ), date2.ToString( "yyyyMMddHHmmss" ) );

Good addition.

That is better code than what I have implemented. Thank you for the insight.
