The WebClient class also includes methods for uploading resources to web servers. First of all, make sure you have the appropriate using statement in place, as follows. This is needed in order to use the WebClient class without requiring a fully qualified namespace. The WebClient class itself is really easy to use. The very simplest example of downloading a file is as follows.
The DownloadFile method accepts a URL to download a file from and a local file path to download the file to. All of the above happens synchronously i. Unfortunately, the DownloadFile method does not provide a way of reporting progress, as it is a synchronous method. However, there is a built-in way of asynchronously downloading a file and reporting progress with the WebClient class, as demonstrated in the example below.
The above code is very similar to the synchronous example. The DownloadProgressChanged event is fired periodically as the download progresses and provides access to some useful properties such as BytesReceived and ProgressPercentage. As expected, the DownloadFileCompleted event is fired whenever the file download has completed. As it stands, the above code will continue past the DownloadFileAsync method call while the download is in progress, since it is an asynchronous method call.
In order to download the file asynchronously using the DownloadFileAsync method and wait until the download has completed before continuing program execution, we need to dip into the world of reset events. The AutoResetEvent in the above code allows us to wait at the point where the WaitOne method is called. When the DownloadFileCompleted event is fired, the Set method on the AutoResetEvent sends a signal that allows the code to proceed to the next statement.
I need to download pdf files from a specified links url to a specific folder in a windows application using winforms please any one can suggest me with a solution.
You can use the WebClient. DownloadFile method, available since. NET 2. It is usable from any type of application, not just Winforms. You should be aware that DownloadFile blocks until the entire file finishes downloading. To avoid blocking you can use the WebClient. DownloadFileAsync method that will download in the background and raise the DownloadFileCompleted event when downloading finishes. You could just "search the web" aka google for "C download file", and end up with this simple MSDN example modified to fit your specific question :.
If not the Target path is not specified and if you give it like file. StartupPath as the name of file. I think this will help a bit more. I could not get it at first site of sample codes provided by MSDN and at last i found this.
