); } } class Program { static async Task Main(string[] args) { AsyncExample example = new AsyncExample(); await example.DoSomethingAsync(); } } 在这个示例中,DoSomethingAsync方法是一个异步方法,它使用await关键字等待Task.Delay的完成,这是一个模拟异步操作的简便方法。 3. 阐述异步编程的好处...
在处理该操作时,用户可以直接取消请求,或刷新页面(这会有效地取消原始请求,并启动新请求)。 [HttpGet(Name = "get")]public async Task<string> GetAsync{try{_logger.LogInformation("request in");await Task.Delay(5 * 1000);_logger.LogInformation("request end");}catch (Exception ex){_logger.LogIn...

}publicTask<TodoItem[]>GetIncompleteItemsAsync() { Task<TodoItem[]> res = _context.TodoItems.Where(x => x.IsDone ==false).ToArrayAsync();returnres; } } } 也可以看到几乎和控制器的实现思路是一致的,因此为了让依赖注入能被实现,需要我们将注入的方法,在这里是构造函数声明为public。
