Async wait for file to be created

Question

What would be the cleanest way to await for a file to be created by an external application?

    async Task doSomethingWithFile(string filepath)         


        

Answer 1

This is how I'd do it:

await Task.Run(() => {while(!File.Exists(@"yourpath.extension")){} return;});
//do all the processing

You could also package it into a method:

public static Task WaitForFileAsync(string path)
{
    if (File.Exists(path)) return Task.FromResult
