What do you mean by "start them in parallel"? When you run the Task
, it executes on another thread, so you probably mean simply:
foreach(var task in myTaskList)
{
task.Start();
}
But if you have so many of them that you want to move the starting logic to another thread, you can either call the above code in another thread/task (I'm using List<T>.ForEach
for shorter code).
Task.Factory.StartNew(() => myTaskList.ForEach(task => task.Start()));
Or you can use TPL's Parallel.ForEach
. That would still block the executing thread until all the Tasks are started, but it will execute the start action on an internal threadpool, so for large numbers of items and some free CPU cores/threads, it might speed up the starting considerably.
Parallel.ForEach(myTaskList, task => task.Start());
