This code for upload file and save into server specific location if ((FileUploadVideo.PostedFile != null) && (FileUploadVideo.PostedFile.ContentLength > 0)) { string fnv = System.IO.Path.GetFileName(FileUploadVideo.PostedFile.FileName); string[] fileVExtArr = fnv.Split('.'); string fileVExt = ""; if (fileVExtArr.Length > 1) { fileVExt = fileVExtArr[1]; fileVExt = fileVExt.ToLower(); } fnv = System.IO.Path.GetFileNameWithoutExtension(FileUploadVideo.PostedFile.FileName); fnv = fnv + "_" + DateTime.Now.ToString("ddMMyyyyhhmmss") + "." + fileVExt; if (!fileVExt.Equals("mp4") && !fileVExt.Equals("flv") && !fileVExt.Equals("3gp") && !fileVExt.Equals("avi")) // { Page.ClientScript.RegisterStartupScript(this.GetType(), "22222", " alert('File type not matched. Please upload only mp4,3gp,avi and flv file') ", false); CheckResult = false; } SaveVideoLocation = Server.MapPath("Video") + "\" + fnv; FileUploadVideo.PostedFile.SaveAs(SaveVideoLocation); } This code for download video from server to client string filepath = Server.MapPath(ViewState["VideoPath"].ToString()); // Create New instance of FileInfo class to get the properties of the file being downloaded FileInfo myfile = new FileInfo(filepath); // Checking if file exists if (myfile.Exists) { // Clear the content of the response Response.ClearContent(); // Add the file name and attachment, which will force the open/cancel/save dialog box to show, to the header Response.AddHeader("Content-Disposition", "attachment; filename=" + myfile.Name); // Add the file size into the response header Response.AddHeader("Content-Length", myfile.Length.ToString()); // Set the ContentType Response.ContentType = ReturnExtension(myfile.Extension.ToLower()); // Response.ContentType = "application/octet-stream"; // Write the file into the response (TransmitFile is for ASP.NET 2.0. In ASP.NET 1.1 you have to use WriteFile instead) Response.TransmitFile(myfile.FullName); // End the response Response.End(); }
