Parallel.ForEach与Task.Run和Task.WhenAll

Question

使用Parallel.ForEach或Task.Run（）异步启动一组任务之间有什么区别？版本1：List<string> strings = new List<string> { "s1", "s2", "s3" };Parallel.ForEach(strings, s =>{    DoSomething(s);});版本2：List<string> strings = new List<string> { "s1", "s2", "s3" };List<Task> Tasks = new List<Task>();foreach (var s in strings){    Tasks.Add(Task.Run(() => DoSomething(s)));}await Task.WhenAll(Tasks);
