Download file from web and then save with a save file dialog box?

Question

How can I download a file, then save it to wherever I want? I am using Windows Form, Web Application.

I know I can download it with this code:

WebClient wClient = new WebClient();
wClient.DownloadFile("WebLinkHere", @"C:\File.txt");

But I want a save box like when you press CTRL+S.

Answer 1

You can use SaveFileDialog class. Example:

var dialog = new SaveFileDialog();
dialog.Filter = "Archive (*.rar)|*.rar";

var result = dialog.ShowDialog(); //shows save file dialog
if(result == DialogResult.OK)
{
    Console.WriteLine ("writing to: " + dialog.FileName); //prints the file to save

    var wClient = new WebClient();
    wClient.DownloadFile("WebLinkHere", dialog.FileName);
}

will show next dialog and if you search for next folder

application will print:

writing to: C:\Temp\archiveName.rar

This will work and open the file download popup.

String FileName = "FileName.xls";
            Response.ClearContent();
            Response.Buffer = true;
            Response.AddHeader("content-disposition", string.Format("attachment; filename={0}", FileName));
            Response.ContentType = "application/ms-excel";
            StringWriter stringWriter = new StringWriter();
            HtmlTextWriter htmlTextWriter = new HtmlTextWriter(stringWriter);
            Response.Write(stringWriter.ToString());
            Response.End();
