C#等价于Objective-C'；s dispatch_group和queue

我正在将Objective-C应用程序移植到C#，我正在努力在C#中实现以下功能

// create a new dispatch group
dispatch_group_t dispatchGroup = dispatch_group_create();
dispatch_queue_t dispatchQueue = dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0);
    // iterate over a collection adding blocks to the dispatchQueue identified by dispatchGroup
    dispatch_group_async(dispatchGroup, dispatchQueue, ^{
        // do stuff
    });
}
// wait for them all to finish
dispatch_group_wait(dispatchGroup, DISPATCH_TIME_FOREVER);
// do more stuff that depends on them all finishing

我该怎么做这样的事？

注意：这至少需要4.5版本的.NET Framework。

// create a new dispatch group
List<Task> tasks = new List<Task>();
// iterate over a collection adding tasks to the dispatch group
for (…) {
    Task task = Task.Run(() => {
        // do stuff
    });
    tasks.Add(task);
}
// wait for them all to finish
Task.WaitAll(tasks.ToArray());
// do more stuff that depends on them all finishing
