How do I wait until Task is finished in C#?

Question

I want to send a request to a server and process the returned value:

private static string Send(int id)
{
    Task responseTask =

I'm an async novice, so I can't tell you definitively what is happening here. I suspect that there's a mismatch in the method execution expectations, even though you are using tasks internally in the methods. I think you'd get the results you are expecting if you changed Print to return a Task:

private static string Send(int id)
{
    Task responseTask = client.GetAsync("aaaaa");
    Task result;
    responseTask.ContinueWith(x => result = Print(x));
    result.Wait();
    responseTask.Wait(); // There's likely a better way to wait for both tasks without doing it in this awkward, consecutive way.
    return result.Result;
}

private static Task Print(Task httpTask)
{
    Task task = httpTask.Result.Content.ReadAsStringAsync();
    string result = string.Empty;
    task.ContinueWith(t =>
    {
        Console.WriteLine("Result: " + t.Result);
        result = t.Result;
    });
    return task;
}
