call event asynchronously in wcf service

Question

I am implementing a third party service to get some feeds. sample code below. when I call the GetLiveFeed function the response is returned through an event HandleEvent.

public class WebComponent
{
    public string livefeed = string.Empty;

    public static string GetSerivceRequest()
    {
        WebComponent obj = new WebComponent();
        obj.GetResult();

        return obj.livefeed;
    }

    public void GetResult()
    {
        Service abc = new Service();
        abc.GetLiveFeed();
    }

    public void HandleEvent(Event eventObj)
    {
        livefeed = "Value from third party service";
    }

}

I want to wait in the static function Getservice until the event is raised and value is assigned in the livefeed variable. But as of now I am only getting blank value. if I put thread.sleep than I get value which I don't want to use

Answer 1

I was able to make the parent thread wait until the execution finishes in the child thread using AutoresetEvent functionality
