问是否可以调用2API并同时显示组合的应答字符串？

static bool SameFace(Microsoft.ProjectOxford.Face.Contract.FaceRectangle r1,
        Microsoft.ProjectOxford.Common.Rectangle r2)
{
    // Fuzzy match of rectangles...
    return Math.Abs((r1.Top + r1.Height / 2) - (r2.Top + r2.Height / 2)) < 3 && 
        Math.Abs((r1.Left + r1.Width / 2) - (r2.Left + r2.Width / 2)) < 3;
}

void Test(string imageUrl)
{
    var faceClient = new FaceServiceClient(FACE_API_KEY);
    var emotionClient = new EmotionServiceClient(EMOTION_API_KEY);

    var faceTask = faceClient.DetectAsync(imageUrl, false, false, new FaceAttributeType[] { FaceAttributeType.Age, FaceAttributeType.Gender });
    var emotionTask = emotionClient.RecognizeAsync(imageUrl);

    Task.WaitAll(faceTask, emotionTask);

    var people = from face in faceTask.Result
                 from emotion in emotionTask.Result

                     emotion.Scores

    // Do something with 'people'
}
