C# Async return value


Here is some code I got from a previous solution. Is it possible to get a return value from an Async call without the caller being an async. I am probably not understanding it exactly - but it seems I have keep layering async calls on async calls to do it.

Anyway here is the code below.
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace Async1
    class YourClass
        async public Task<string> Test1()
            string html = string.Empty;

            using (System.Net.Http.HttpClient client = new System.Net.Http.HttpClient())
                System.Net.Http.HttpResponseMessage response = await client.GetAsync("http://www.experts-exchange.com/Programming/Languages/C_Sharp/Q_28686082.html");

                html = await response.Content.ReadAsStringAsync();

            return html;

    // http://www.experts-exchange.com/Programming/Languages/C_Sharp/Q_28686082.html

    class Program
        static void Main(string[] args)
            YourClass instance = new YourClass();

            Task t = instance.Test1().ContinueWith(AfterDownload);

           // So I would like to be able to get return value from the function without having to make this an Async method.
          // So not using the ContinueWith method above.
          // Is this possible?


            Task x = instance.Test1();



        private static void AfterDownload(Task<string> html)

Yes, you can, but you cannot use the await keyword. You simply call the async method without await and leave the async off of the caller. Your async method returns a Task, so just capture that and inspect its Result property. Keep in mind that inspecting Result is blocking, so you will no longer be async.


Task t = instance.Test1()
string html = t.Result;

The unspoken idea behind async/await is that you do make things async all the way down--unless there's a reason why you need to go synchronous, and then you'd refer to the Result property as above.
