c# - save as dialog in asp.net

Question

I have some data in the form of a string. I want to write this data to a file and save the file to the specified path. The path would be specified by opening a save as dialog on the button click. How can this be achieved??

Answer 1

The file is saved into the server initially with this code

string getnote = txtdisplay.Text.Trim();
        String filepath = Server.MapPath(@"img
ew1.txt");
        System.IO.FileStream ab = new System.IO.FileStream(filepath, System.IO.FileMode.Create);
        System.IO.StreamWriter Write101 = new System.IO.StreamWriter(ab);
        Write101.WriteLine(getnote);
        Write101.Close();
        Response.ClearContent();

From the server get the file as attachment.Use the following code for save as dialog box for downloading or saving the file. The file will save by default in the download folder. To save to the specified location change the browser settings.

Response.ContentType = "text";
        Response.AppendHeader("Content-Disposition", "attachment; filename=new1.txt");
        Response.TransmitFile(Server.MapPath("~/img/new1.txt"));
        Response.End();
