upload, download and delete a video using asp.net in c#

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", "", 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();

}

Hello Chiranjeevi Aripaka,
It seems like your requirement is almost a module. I would suggest you to start doing at your own and let us know the particular step, where you got stuck.
