Open file and save

Question

I want to download a file and save it locally without any pop ups for user to choose location since its predefined. File format will most probably be pdf. Download file path will be an url and I want to save it locally. Do I go to work like this:

string fileName = "http://mail.example.com/download.asp?saveFile=example.pdf";  

BinaryReader binReader = new BinaryReader(File.Open(fileName, FileMode.Open));  

string path = "C:\\Domains\\shared.example.com\\pdf\\example.pdf";  

using (BinaryWriter Writer = new BinaryWriter(new FileStream(path,FileMode.OpenOrCreate)))  
{  
    Writer.Write(binReader);  
}

Answer 1

You should tag which language you're using.

Also I don't believe browsers would let a file be downloaded without asking the user first as this is a security issue. You could easily throw viruses on to people's computers without them knowing.

Answer 2

No, that's not working that way...you'll have to use the WebRequest-Class for acquiring the file.

Answer 3

Using

new WebClient().DownloadFile("http://url/name.pdf", @"C:\locationOnFilesystem.pdf");

You can use DownloadFileAsync to do this without blocking your main thread. Attach event handlers to the WebClient to report progress, like DownloadProgressChanged and DownloadFileCompleted.

Answer 4

This is easier:

WebClient wc = new WebClient();
wc.DownloadFile(filename, path);
