C# first drag n drop the input(file) in the html controls which r in tool box of studio. by this one u can browse n select a file from local system which has to upload to server. after that in submit or upload button write the following code. int size = FilePath.PostedFile.ContentLength; int _size = Convert.ToInt32(size); byte[] sound = new byte[size]; string filePath = System.IO.Path.GetFullPath(FilePath.PostedFile.FileName); FileStream _fs = new FileStream(filePath, FileMode.OpenOrCreate); _fs.Read(sound, 0, size); _fs.Close(); here FilePath is the tool name i.e id given to input(file) from html controls. then insert this byte array i.e sound to database use varbinary or image datatype in datbase to hold this byte array. dont forgot to include runat = server for the Html input(file) in that source code. other wise u wont get this name FilePath in ur .cs class

Here is the code for the uploading the documents in to the server:

<%@ Page Language="vb" %> <html> <Script Language="VB" RunAt="Server"> Sub Page_Load(Sender as Object, e as EventArgs) Dim MyPath, MyName as string ' Display the names in C:\ that represent directories. MyPath = "C:\ServerFolder" ' Set the path. MyName = Dir(MyPath, vbDirectory) ' Retrieve the first entry. if MyName="" ' The folder is not there & to be created MkDir("C:\ServerFolder\") 'Folder created span2.InnerHtml="A Folder (C:\ServerFolder) is created at the Page_Load" end if End Sub Sub Upload_Click(Sender as Object, e as EventArgs) ' Display properties of the uploaded file FileName.InnerHtml = MyFile.PostedFile.FileName FileContent.InnerHtml = MyFile.PostedFile.ContentType FileSize.InnerHtml = MyFile.PostedFile.ContentLength UploadDetails.visible = True ' Let us recover only the file name from its fully qualified path at client Dim strFileName as string strFileName = MyFile.PostedFile.FileName Dim c as string = System.IO.Path.GetFileName(strFileName) ' only the attched file name not its path ' Let us Save uploaded file to server at C:\ServerFolder\ Try MyFile.PostedFile.SaveAs("C:\ServerFolder\" + c) Span1.InnerHtml = "Your File Uploaded Sucessfully at server as : C:\ServerFolder\" & c catch Exp as exception span1.InnerHtml = "An Error occured.

Here is the code to download using a button. Copy and paste it on button_click event
Dim filename As String filename = --give the file name Dim filepath As String = --Mention the file path Dim fs As FileStream Dim strContentType As String fs = File.Open(filepath, FileMode.Open) Dim bytBytes(fs.Length) As Byte fs.Read(bytBytes, 0, fs.Length) fs.Close() Response.AddHeader("Content-disposition", "attachment; filename=" & filename) Response.ContentType = "application/txt" Response.BinaryWrite(bytBytes) Response.End()
