DownloadFile – Method that downloads a single file over HTTP ; For the download demo application, my goal is to download files over an HTTP connection. The application uses the System.Net.WebRequest and System.Net.HttpWebRequest classes to interact with the HTTP server, such as request for data and retrieve response from the server. This site uses cookies for analytics, personalized content and ads. By continuing to browse this site, you agree to this use. Learn more Worse yet, it does that for every subsequent request. I fail to see why WebClient insists on not sending the authorization header in the first place. After all, if the coder specifies the Credentials property, he must already know that the page requires authorization and WebClient should just obey and send in the header without the fuss. WebClient allows you to deal with your requests and responses with strings, byte arrays, files, or streams. Unfortunately, you can't use WebClient all the time; some features such as cookies are only available with WebRequest and WebResponse. You can't use the same instance of WebClient to perform repeated requests in sequence. Thanks jrv, you are always there. I was able to do this and it downloads file. However file contains dummy text indicating me to sign in. I think its classic way of saying 401 at first request (client should not send credentials at first), and then using actual creds. The OpenEdge® WebClient™ is an ABL GUI client that allows you to deploy OpenEdge applications remotely. The WebClient runs as a freestanding, thin client on the end user's PC while executing ABL code and commnicating with the Progress AppServer™ remotely. Typically you can simply introduce a link to the endpoint of the file download into the page and this will work just fine. However, if you use authentication via bearer token etc. and the download endpoint needs authentication, you probably want to use the HttpClient in order to make that download request.

Now what I need to do is be able to extract certain data from the site and put it into a csv or text file. Any thoughts there or any articles you know of that would better explain doing that? Cheers.

This method blocks while downloading the resource. To download a resource and continue executing while waiting for the server's response, use one of the DownloadStringAsync methods. Downloads the resource with the specified URI to a local file. DownloadFile(Uri, String) Downloads the resource with the specified URI to a local file. DownloadFileAsync(Uri, String) Downloads, to a local file, the resource with the specified URI. This method does not block the calling thread. DownloadFileAsync(Uri, String, Object) The alternative approach to downloading files is to use HttpClient. Ultimately it results in the same behavior most likely. WebClient is my preferred approach for simple downloads. HttpClient is better suited for complex REST calls.
