I am using this code to retrieve an url content:
private ArrayList request(string query)
{
ArrayList parsed_output = new ArrayList();
string url = string.Format(
"http://url.com/?query={0}",
Uri.EscapeDataString(query));
Uri uri = new Uri(url);
using (WebClient client = new WebClient())
{
client.DownloadStringAsync(uri);
}
// how to wait for DownloadStringAsync to finish and return ArrayList
}
I want to use DownloadStringAsync
because DownloadString
hangs the app GUI, but I want to be able to return the result on request
. How can I wait until DownloadStringAsync
finish the request?
With Dot.Net 4.5:
public static async void GetDataAsync()
{
DoSomthing(await new WebClient().DownloadStringTaskAsync(MyURI));
}
