I’m using an API client that is completely asynchrounous, that is, each operation either returns Task or Task<T>, e.g: static async Task DoSomething(int siteId, int postId, IBlogClient client) { await client.DeletePost(siteId, postId); // call API client Console.WriteLine(“Deleted post {0}.”, siteId); } Using the C# 5 async/await operators, what is the correct/most efficient way to start … Read more
In the code below, due to the interface, the class LazyBar must return a task from its method (and for argument’s sake can’t be changed). If LazyBars implementation is unusual in that it happens to run quickly and synchronously – what is the best way to return a No-Operation task from the method? I have … Read more
I am trying to use the new async features and I hope solving my problem will help others in the future. This is my code which is working: async function asyncGenerator() { // other code while (goOn) { // other code var fileList = await listFiles(nextPageToken); var parents = await requestParents(fileList); // other code } … Read more
I’m developing a console script for personal needs. I need to be able to pause for an extended amount of time, but, from my research, Node.js has no way to stop as required. It’s getting hard to read users’ information after a period of time… I’ve seen some code out there, but I believe they … Read more
When you have server-side code (i.e. some ApiController) and your functions are asynchronous – so they return Task<SomeObject> – is it considered best practice that any time you await functions that you call ConfigureAwait(false)? I had read that it is more performant since it doesn’t have to switch thread contexts back to the original thread … Read more
I am learning about async/await, and ran into a situation where I need to call an async method synchronously. How can I do that? Async method: public async Task<Customers> GetCustomers() { return await Service.GetCustomersAsync(); } Normal usage: public async void GetCustomers() { customerList = await GetCustomers(); } I’ve tried using the following: Task<Customer> task = … Read more
I can mark a JavaScript function as “async” (i.e., returning a promise) with the async keyword. Like this: async function foo() { // Do something } What is the equivalent syntax for arrow functions? 8 s 8 Async arrow functions look like this: const foo = async () => { // do something } Async … Read more
I have a public async void Foo() method that I want to call from synchronous method. So far all I have seen from MSDN documentation is calling async methods via async methods, but my whole program is not built with async methods. Is this even possible? Here’s one example of calling these methods from an … Read more
From my understanding one of the main things that async and await do is to make code easy to write and read – but is using them equal to spawning background threads to perform long duration logic? I’m currently trying out the most basic example. I’ve added some comments inline. Can you clarify it for … Read more
Are there any issues with using async/await in a forEach loop? I’m trying to loop through an array of files and await on the contents of each file. import fs from ‘fs-promise’ async function printFiles () { const files = await getFilePaths() // Assume this works fine files.forEach(async (file) => { const contents = await … Read more
