Download zip file from a URL

Good evening, I need to download a zip file and save to a server, however, with the code I am using below, it just creates the zip file on the server; when opening it, there is no file in it and is given the following message: Unsupported ARCHIVE type.

Inside this zip file, we have two json files. By calling the URL by the browser, it automatically downloads.

            var localPath = @"\\nomeServidor\\nomepasta\\" + nomeArquivo;

            WebClient webClient = new WebClient();
            webClient.DownloadFileAsync(new Uri(link), localPath);

            while (webClient.IsBusy) { }

            return Request.CreateResponse(HttpStatusCode.OK);

Could someone help me in possible solutions?

You don’t have to do this gambit with while, you can use the downloadfile without being async, because you don’t need it async.

In case your code would be:

  var localPath = @"\\nomeServidor\\nomepasta\\" + nomeArquivo;
  using (var client = new WebClient())
  {
    client.DownloadFile(localPath);
  }

This code should work because as far as I know the downloadfile does not distinguish from file type. If it does not work, make sure it is not a problem in the downloaded file or if the user running the program has permissions to access localPath.

  • Paul, I changed the code, but unfortunately it didn’t work. I am running location on my machine and have access to folder, however it writes an empty zip file.

  • Try to require administrator permissions to run your program. To do this, add the following line in your application’s manifest: <requestedExecutionLevel level="requireAdministrator" uiAccess="false" />&#xA;

  • Still nothing.. :/

  • What error? could give more information? Can you download the file normally through the browser?

  • There is no error in the application. By the browser, the file is downloaded normally, with its correct content. By the application, a zip file is created only without content. It might be something related to link permission?

  • Paulo, problem solved rsrs It really was the authentication. So beast that you can’t believe kkkkk Thank you!

  • It was nothing, can you mark the answer as right? It helps the community :)
