Question

我是C＃中异步模式的新手，并尝试使用Asp.Net核心。

我希望在从Middleware_NotifyWPF中的控制器操作收到响应后调用方法InformUI（）。怎么做？ [类似于Middleware_NotifyWPF的request.on（＆＃39; end＆＃39;）事件处理程序。]

Startup.cs：

  public void Configure(IApplicationBuilder app, IHostingEnvironment env, ILoggerFactory loggerFactory)
        {
            app.Middleware_NotifyWPF();
            app.UseMvc();
        }

中间件1：

    public class Middleware_NotifyWPF
        {
            private readonly RequestDelegate _next;
            private static Logger _logger = LogManager.GetCurrentClassLogger();

            public Middleware_NotifyWPF(RequestDelegate next)
            {
                _next = next;
            }

            public Task Invoke(HttpContext httpContext)
            {
                return _next(httpContext);


                InformUI(httpContext.Request, httpContext.Response); //Unreachable code
            }
}

控制器类|行动方法

        [HttpGet("{id}")]
        public string Get(int id)
        {
            return "value";
        }

您需要等待任务才能在

之后到达代码

public async Task Invoke(HttpContext httpContext)
{
    await _next(httpContext);

    InformUI(httpContext.Request, httpContext.Response); 
}

Asp.Net核心：从另一个中间件
