WebClient.DownloadFile

WebClient.DownloadFile

I am using the WebClient.DownloadFile function to download a file from
server to a local client.

When I execute the below code, file is created in server and not in client.

WebClient wc = new WebClient();
wc.DownloadFile(strFileFrom, strFileTo);

What am I doing wrong?

Tks.

You can't force a download to a client like that. The code is being executed
on the server.

You want to do something like this

or this:

Are you using WebClient's downloadfile method through an application
that resides on server? You must invoke method from a client that
should download data from a remote host(server).

If you are running asp.net and you want the browser to download it ,
then look at the following code. I found it online.If that does not
work, you will have to do something similar.

// Clear the content of the response

Response.ClearContent();

// LINE1: Add the file name and attachment, which will force the open/
cance/save dialog to show, to the header
Response.AddHeader("Content-Disposition", "attachment; filename=" +
file.Name);

// Add the file size into the response header
Response.AddHeader("Content-Length", file.Length.ToString());

// Set the ContentType

Response.ContentType = ReturnExtension(file.Extension.ToLower());

// 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(file.FullName);

I have an asp.net application that runs in IIS.
I have files in IIS server, and I want from IE client download and save
these files in the local client.

In that case, you just want to use something like TransmitFile at the
server to send the file down to the client (in place of the normal
response):

Alternatively, you just have a hyperlink from the client to the file in
IIS, and ensure that IIS adds the Content-Disposition: Attachment
http-header.

(note that you won't be able to choose the destination; the user has to
accept the file and location)
