How do I want untill is finished in C#?
- by Grienders
Let's say, I want to send a request to a server and get a result from it:
private static string Send(int id)
{
Task<HttpResponseMessage> responseTask = client.GetAsync("aaaaa");
string result = string.Empty;
responseTask.ContinueWith(x => result = Print(x));
responseTask.Wait(); // it doesn't wait for complemeting of response task
return result;
}
private static string Print(Task<HttpResponseMessage> httpTask)
{
Task<string> task = httpTask.Result.Content.ReadAsStringAsync();
string result = string.Empty;
task.ContinueWith(t =>
{
Console.WriteLine("Result: " + t.Result);
result = t.Result;
});
task.Wait(); // it does wait
return result;
}
Am I using task correct? I don't think so because Send() method return string.Empty all the time, while Print returns the correct value.
What am I doing wrong? How do I get a result from a server?
