c# - How to wait for async void to complete?

i need to wait for my async void to finish. It has some await Task.Delay functions in it and I need them to finish before it continues. This void doesn't return anything so I don't see a reason to make it async Task<> and I also shuffle an array inside this void and I declare some variables. So how can I do this ? Is async Task<> the only way ? My void is not expecting any parameters/inputs.

See Question&Answers more detail:os

Return Task (not Task<T>) instead of void. Note, the non-generic form of Task does not need to wrap a value. It's just for signalling completion or errors, not results. In the case of async methods, this is equivalent to a synchronous void return type. It means you can wait for your method to complete.
