C# async tasks in a queue or waiting list

Question

i have an async Task like this:

public async Task DoWork()
{

}

And i have at the moment a:

List tmp = new List<         


        

Answer 1

Actually, the tasks start as soon as you call DoWork; when you await them, you are finishing the tasks.

One option for throttling tasks is SemaphoreSlim, which you can use as such:

private SemaphoreSlim _mutex = new SemaphoreSlim(3);
public async Task DoWorkAsync()
{
  await _mutex.WaitAsync();
  try
  {
    ...
  }
  finally
  {
    _mutex.Release();
  }
}

Another option is to use an actual queue, like an ActionBlock<T>, which has built-in throttling support.
