大家好，

请问各位高手，方式1与方式2有什么区别。

方式1

public async Task<IDictionary<string, object>> Get()
{
HttpConfiguration configuration = new HttpConfiguration();
configuration.Routes.MapHttpRoute("default", "wheather/{areaCode}/{days}");
MyHttpRoutingDispatcher dispatcher =
new MyHttpRoutingDispatcher(configuration);
HttpRequestMessage request = new HttpRequestMessage(HttpMethod.Get, "http://www.artech.com/wheather/010/2");

await dispatcher.SendAsync(request, CancellationToken.None);
IHttpRouteData routeData = request.GetRouteData();
return routeData.Values;
}

方式2【去除async,await】

public IDictionary<string, object> Get()
{
HttpConfiguration configuration = new HttpConfiguration();
configuration.Routes.MapHttpRoute("default", "wheather/{areaCode}/{days}");
MyHttpRoutingDispatcher dispatcher =
new MyHttpRoutingDispatcher(configuration);
HttpRequestMessage request = new HttpRequestMessage(HttpMethod.Get, "http://www.artech.com/wheather/010/2");

dispatcher.SendAsync(request, CancellationToken.None);
IHttpRouteData routeData = request.GetRouteData();
return routeData.Values;
}
