I'm currently writing a C# console app that generates a number of urls that point to different images on a web site and then downloads those URLs as byte streams using WebClient.DownloadDataAsync. My issue is that once the first asynchronous call is made, the console app considers the program to be completed and terminates before the as...
When using WebClient to download data there seems to be some minor but perceivable delay incurred each time from resolving the proxy. Since I need to call the methods using the webclient multiple times in different threads and webclient itself isn't thread safe I was thinking of instead just creating a new webclient each time and settin...
Using the following code (from a Silverlight 4 OOB app) I'm getting a result stream with a size of zero even though it takes the time to download the whole file (900+MB) and no error is reported. Fiddler also says the whole file was downloaded. The handler on progress changed (although not shown below) is hit and reports an increase in ...

Hi, I have a problem with sending a POST request from C# to a PHP script on my Apache (Windows) server. Everything works fine, unless I instruct Apache to require a valid user using BASIC authentication through a .htaccess file. But let's put things in order.

I'm using C# WebClient(); to download a file from a server. The problem is when I don't have internet or the server is not responsive, my application crashes trying to download this file.

I'm using System.Net.WebClient to perform some HTTP operations in asynchronous mode. The reason to use asynchronous operations is, above anything else, the fact that I get progress change indications - which is only available for async operations, as stated by the docs. So let's say I have my WebClient set up: this.client = new WebClie...

What features do you want to see in System.Net.HttpWebRequest and System.Net.WebClient that are not included out of the box? What cannot or cannot be easily achieved with those classes? I'd like to be able to: Use bandwidth throttling when downloading (useful for large files). Upload multiple files and key-value pairs via HTTP post ...
