以下是使用异步等待的示例。 当我们执行任何代码时，等待httpcontext变为空 我尝试过：

Below is the sample of using async await. when ever we execute any code inside await httpcontext is getting null What I have tried:

//Here is the sample of Async Function in which i cant get Httpcontext public async Task<string> Get(int id) { var x = HttpContext.Current; if (x == null) { // not thrown throw new ArgumentException("HttpContext.Current is null"); } await Task.Run(() => { GetRealId(); }); return "value"; } //HttpContext Getting null here.. public void GetRealId() { var r = HttpContext.Current; }

简单的艺术：ASP.NET Web API：HttpContext.Current在任务内部为null [ ^ ]（5秒google搜索结果） The art of simplicity: ASP.NET Web API: HttpContext.Current is null inside Task[^] (result of 5 seconds of googling)

您需要将httpcontext存储在函数范围之外，如类成员或静态。 我想它可能会超时。设置更高的超时。 You need to store the httpcontext outside the scope of your function like a class member or as static. I guess it may timed out. Set the timeouts higher.
