ASP.NET sample code for uploading and downloading files
There are lots of situation, Where we have to use file uploader in our project. But beginners don’t get proper code for Uploading and Downloading File. Using this code they can do it:

File Upload Code

string FilePath = "";
string[] a = new string[1];
string fileName = "";
string FullName = "";
if (FileUploader.FileName.Length > 0)
     a = FileUploader.FileName.Split('.');
     fileName = Convert.ToString(System.DateTime.Now.Ticks) + "." + a.GetValue(1).ToString();
     FilePath = Server.MapPath(@"~\SavedFolder");
     Fup1.SaveAs(FilePath + @"\" + fileName);
     FullName = FilePath + @"\" + fileName;
     // Database Saved Code

File Download Code

string filename = "filename from Database";
Response.ContentType = "application/octet-stream";
Response.AppendHeader("Content-Disposition", "attachment;filename=" + filename);
string aaa = Server.MapPath("~/SavedFolder/" + filename);
Response.TransmitFile(Server.MapPath("~/SavedFolder/" + filename));
