我们有这种方法:
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;
}
Task<int>和之间是否发生隐式转换int?如果没有,那是怎么回事?如何实施工作?

async关键字来处理该问题。
