Question

I am using VS2005 c#.

I have this function for converting pipe delimited text files into excel format.

The files will then be stored in the C:\ of the user PC.

However, when I deployed my web application into the test server, the files are saved in the C:\ of the test server instead.

Below is my code snippet, may I know how can I change it to be saved on the users’ pc instead of the server’s, or if possible, show a popup message for the user to open/save the file. Thank you

if (TextFile.HasFile)
    {
        string strFileName = Server.HtmlEncode(TextFile.FileName);

        string strExtension = Path.GetExtension(strFileName);

            string activeDir = @"C:\";

            string newPath = System.IO.Path.Combine(activeDir, "App_Converted");

            System.IO.Directory.CreateDirectory(newPath);

            string strExcelOutputFilename = "C:/App_Converted/" + xlExtension;

            using (StreamWriter outputWriter = new StreamWriter(File.Create(strExcelOutputFilename)))
            {
                StreamReader inputReader = new StreamReader(TextFile.FileContent);
                while (inputReader.Peek() >= 0)
                {
                    string[] myInputFields = inputReader.ReadLine().Split(new char[] { '|' });
                    List<string> myOutputFields = new List<string>();

                    foreach (string aField in myInputFields)
                    {
                        string oField = aField;
                        if (oField.Contains(","))
                            oField = "\"" + oField + "\"";

                            myOutputFields.Add(oField);
                    }

                    outputWriter.WriteLine(string.Join(",", myOutputFields.ToArray()));

                }
                inputReader.Close();
                UploadStatusLabel.Text = "File stored at [C:/App_Converted/] as file name [namelist.csv]";
                Response.Clear();
                Response.ContentType = "application/vnd.xls";
                Response.AddHeader("Content-Disposition", "attachment;filename=namelist.csv");

                StringWriter swriter = new StringWriter();
                HtmlTextWriter hwriter = new HtmlTextWriter(swriter);

                Response.Write(swriter.ToString());
                Response.End();
                return;
            }

EDIT:

Updated code with save windows. However, I do not know how to link my converted file to the save windows. Need some help here. Above is my updated code.

Answer 1

instead of:

    Response.ContentType = "application/vnd.xls";
    Response.AddHeader("Content-Disposition", "attachment;filename=namelist.csv");

    StringWriter swriter = new StringWriter();
    HtmlTextWriter hwriter = new HtmlTextWriter(swriter);

    Response.Write(swriter.ToString());

use this snippet

    Response.ContentType = "application/vnd.xls";
    Response.AddHeader("Content-Disposition", "attachment;filename=namelist.csv");
    string filePath = @"paste a path of your file here";
    Response.WriteFile(filePath);
