asynchronous

问题 I was having a look at the section on memory barriers as described in http://www.albahari.com/threading/part4.aspx and attempted to make an async/await version of the example provided under 'Do We Really Need Locks and Barriers?': public class Program { static void Main(string[] args) { TestAsync(); Console.ReadKey(true); } private static async void TestAsync() { bool complete = false; Func<Task> testFunc = async () => { await Task.Delay(1000); bool toggle = false; while (!complete) toggle =

问题 As Async always returns promise, we have to resolve it to get the value. I need to export it's value (returned object) so that we can use it in another module. export const getClient = async () => { return await HttpService.getValueFromSettings('durl').then((response) => { if(isValidResponse(response)) { endpoint = response.data; export const client = createClient(response.data); //This is where getting error that we can not export in side the function } } }) } I need to use client in another

问题 Suppose I have a blocking method called check as follows: boolean check(String input) {} which will do some check against the input and return the decision. Now I want to run this check against a list of inputs asynchronously, and I want to return to the main thread right after one of the inputs passing the check, so I don't have to wait for all asynchronous call to be completed. The only one scenario for waiting all threads to complete is that there are no inputs passing the check. Running

问题 i'm currently upgrading some existing code for use by windows universal and am struggling to convert a command pattern to work with the new async/await functionality. I have a command scheduler class that runs within its own thread and processes commands that have been added to its queue. The method in question looks like this: private List<ICommandItem> _items; private void ProcessCommands() { while(_items.count > 0) { _items[0].Execute(); _items.RemoveAt(0); } } My problem is that some of

问题 I'm new to react and I am trying to fetch data from an API and pass the data to a child component. I've passed the data to the state on my parent component, however, when I pass it to the child component as props it logs as an empty array. I'm sure there is something simple I am overlooking but I don't know what, my code is below PARENT COMPONENT import React, {Component} from 'react'; import Child from '../src/child'; import './App.css'; class App extends Component { constructor(props) {
