Question

我正在为Mono编写一个控制台应用程序，试图让HttpClient下载一些内容并用Json.NET反序列化它。

我遇到的问题是当我调用异步方法时出现Stack Overflow。

就像这样，简化为isse的核心：

public static void Main(string[] args){
  ...
  Manager man = new Manager(){...}; // setting up target url, timeouts etc
  man.RenewAuth().Wait(); //it's async but the first time it runs synchronously
  ...
}

public class Manager{
...
async Task<T> GetAsync<T> (string urlAdd)
{
  var httpRes = await Client.GetAsync (Client.BaseAddress + urlAdd);
  string s = await httpRes.Content.ReadAsStringAsync ();
  var deserialized = JsonConvert.DeserializeObject<T> (s);
  return deserialized  ;
}

public async Task RenewAuth () // 
{
  ... // logging in, setting up etc

  // THIS WORKS:
  var aKey = GetAsync<AuthKey> ("/AuthKey?email=" + email).Result; 

  // THIS DOESN'T WORK, CAUSES STACK OVERFLOW:
  var aKey = await GetAsync<AuthKey> ("/AuthKey?email=" + email); 

  ... // store the api auth key from aKey and return
}
}

在控制台中我得到了这个：

事实证明这只在连接调试器时发生，否则代码工作正常。
