我们有这个方法:

async Task<int> AccessTheWebAsync()
{ 
    HttpClient client = new HttpClient();

   Task<string> getStringTask = client.GetStringAsync("http://msdn.microsoft.com");

   // You can do work here that doesn't rely on the string from GetStringAsync.
   DoIndependentWork();

   string urlContents = await getStringTask;
   //The thing is that this returns an int to a method that has a return type of Task<int>
   return urlContents.Length;
}

之间是否隐式转换发生Task<int>和int？如果没有,那么发生了什么？它是如何实现的？
