如何停止自託管 Kestrel 應用程序？

我有規范程式碼可以在任務中自行託管 asp.net mvc 應用程序：

           Task hostingtask = Task.Factory.StartNew(() =>
           {
               Console.WriteLine("hosting ffoqsi");
               IWebHost host = new WebHostBuilder()
                   .UseKestrel()
                   .UseContentRoot(Directory.GetCurrentDirectory())
                   .UseIISIntegration()
                   .UseStartup<Startup>()
                   .UseApplicationInsights()
                   .Build();

               host.Run();
           }, canceltoken);

當我取消此任務時，會拋出 ObjectDisposedException。如何優雅地關閉主機？

找到取消 Kestrel 的最明顯方法。執行有一個接受取消令牌的重載。

 public static class WebHostExtensions
 {
   /// <summary>
   /// Runs a web application and block the calling thread until host shutdown.
   /// </summary>
   /// <param name="host">The <see cref="T:Microsoft.AspNetCore.Hosting.IWebHost" /> to run.</param>
   public static void Run(this IWebHost host);
   /// <summary>
   /// Runs a web application and block the calling thread until token is triggered or shutdown is triggered.
   /// </summary>
   /// <param name="host">The <see cref="T:Microsoft.AspNetCore.Hosting.IWebHost" /> to run.</param>
   /// <param name="token">The token to trigger shutdown.</param>
   public static void RunAsync(this IWebHost host, CancellationToken token);
 }

所以將取消令牌傳遞給

host.Run(ct);

解決它。
