Howto download a file from http-site

[Ariadne]

Hi, is there an example, how to download a (msi) file from a web-site (via http) to the local harddisk in C#? Thanks! Ariadne

Use HttpWebRequest[^] to issue the request for the MSI file, this will be returned in a HttpWebResponse[^] object. You can then stream the data to the local disk.

Thanks Colin, I did this: myReq=HttpWebRequest)WebRequest.Create("http://www.xyz.ch/file.msi"); myResponse = myReq.GetResponse(); ReceiveStream = myResponse.GetResponseStream(); FileStream frStream = new FileStream(ReceiveStream, FileAccess.Read); FileStream fwStream = new FileStream(Application.StartupPath+"file.msi",FileMode.Create,FileAccess.Write); But this does not work: ReceiveStream is not System.IO.Stream Ariadne

If I recall correctly, you need to pass the ResponseStream to a StreamReader. You can then read the contents of the stream to a byte array and then write the array that to your output file stream. The response stream will tell you how large you need to make the byte array (of course, you can always make it smaller and retrieve the information in chunchs by using multiple reads)

Yes Colin, the canonical way works! thanks.:-O Ariadne

have you tried the WebClient class? WebClient w = new WebClient(); w.DownloadFile(address_str,file_str); //if you want to hold the file only in memory, try // w.DownloadData() //for parameters check msdn this is maybe a lot simpler than working with HttpWebRequest objects ;) best regards j.

Yes much more easy! thanks. I now use this WebClient version:) Ariadne
