web api 返回html,webapi 异步返回

两年前我遇到一个难题：

https://q.cnblogs.com/q/78177

现在终于做出一种实现了：

[HttpGet]

public ApiActionResult OnceBackDemo()

{

var result = new ApiActionResult()

{

Success = false,

Result = null,

Message = "操作失败。"

};

System.Threading.ManualResetEvent mre = new System.Threading.ManualResetEvent(false);

mre.Reset();

Random rm = new Random();

Action task = (sw) =>

{

sw.Start();

int rm_val = rm.Next(1000);

System.Threading.Thread.Sleep(rm_val);

};

var sw_out = new Stopwatch();

task.BeginInvoke(sw_out, (ar) =>

{

task.EndInvoke(ar);

mre.Set();

sw_out.Stop();

result.Success = true;

result.Message = DateTime.Now + "->操作成功,耗时：" + sw_out.ElapsedMilliseconds.ToString()+"毫秒。";

}, null);

if (!mre.WaitOne(1500))

{

return result;

}

return result;

}
