如何在c#中将一个类的异步方法调用到另一个类

我有一个接口，它有一个方法原型:

public interface IDataReceiver
{
  Task<HttpResponseMessage> ReceiveAsync(string id, HttpRequestMessage request);
}

我有一个继承接口的抽象类

public abstract class DataReceiver :IDataReceiver
    {
        protected DataReceiver()
        {
        }
         public abstract Task<HttpResponseMessage> ReceiveAsync(string id, HttpRequestMessage request);
         protected virtual async Task<NameValueCollection> ReadAsFormDataAsync(HttpRequestMessage request)
    {
           //code to read the html request body
    }
}

我有另一个类继承DataReceiver

 public  class Reciever1 :DataReceiver
    {
        internal const string TokenParameter = "token";
        public override async Task<HttpResponseMessage> ReceiveAsync(string id, HttpRequestMessage request)
        {
            if (id == null)
            {
                throw new ArgumentNullException(id);
            }
             // Read the request entity body
             NameValueCollection data = await ReadAsFormDataAsync(request);
             string token = data[TokenParameter];
             HttpResponseMessage tstmsg = request.CreateResponse(HttpStatusCode.OK, "Success"+token);
             return tstmsg;
}
}

我有控制器类

 public class TestController : ApiController
    {
        [HttpPost]
        public  Task<HttpResponseMessage> ProcessData(string name)
        {
          retrun   ProcessWebhook(name);
        }
       private async Task<HttpResponseMessage> ProcessWebhook(string RecieverName)
        {
            //how to call the ReceiveAsync method of Reciever1  class
            return Request.CreateResponse(HttpStatusCode.OK, "Success" +" "+ RecieverName);
          }
}

我试图调用ReceiveAsync方法Reciever1类的ProcessWebhook方法TestController类，但不能这样做。我尝试使用classname。methodname方式，但它没有显示方法。

有什么想法吗?

谢谢!
