Call a method Asynchronously in C#
Asynchronous programming in C# is an efficient approach towards activities blocked or access is delayed. If an activity is blocked like this in a synchronous process, then the complete application waits and it takes more time. The application stops responding. Using asynchronous approach, the applications continues with other tasks as well.
An application with a GUI, check the content of the queue and if an unprocessed task is there, it takes it out and processes it first. The code executes synchronously and the unprocessed task is completed first. The application will show stop responding messages if the processing takes more time than expected.
Let us see what is discussed above.
private void OnRequestDownload(object sender, RoutedEventArgs e) {
var req = HttpWebRequest.Create(_requestedUri);
var res = req.GetResponse();
}To solve the above issue, use the async and await keywords.
private async void OnRequestDownload(object sender, RoutedEventArgs e) {
var req= HttpWebRequest.Create(_requestedUri);
var res = await req.GetResponseAsync();
}
