Is there a way to tell which Tasks are currently running in Task Parallel Library?

Question

I can\'t see a way to see which tasks are running. There is the Task.Current property, but what if there are multiple tasks running? Is there a way to get this kind of infor

Answer 1

You can also get the currently running task (or a Task's parent) with reflection:

static public class Extensions
{
    public static Task Parent(this Task t)
    {
        FieldInfo info = typeof(Task).GetField("m_parent", 
            BindingFlags.NonPublic | BindingFlags.Instance);
        return info != null ? (Task)info.GetValue(t) : null;
    }
    public static Task Self
    {
        get
        {
            return Task.Factory.StartNew(
                () => { },
                CancellationToken.None,
                TaskCreationOptions.AttachedToParent,
                TaskScheduler.Default).Parent();
        }
    }
};
