I want run 3 methods at the same time and the others wait until any methods is finish

Hi I want run 3 methods at the same time and the others wait until any methods is finish. How can i do this? Here's what I've done so far. 

public static List<Action> actions;
 public static int ms = 1;    
 public static void s1()
        {
             actions = new List<Action>();
        actions.Add(drivers1);
        actions.Add(drivers2);
        actions.Add(drivers3);
        actions.Add(drivers4);
        var maxThreads = 3;

        int j = 1;
        while (true)
        {
            if (j == 1){
                if (ms <= 3) {
                while (true) { 

                        if (actions.Count() < 1)
                        {
                            j = 0;
                        }
                        else
                        {
                            thread = new Thread(new ThreadStart(actions[0]));
                            thread.Start();



                        }
               }
                }
                else
                {
                    while (true)
                    {
                        if (ms <= 3)
                        {
                            break;
                        }
                        else
                        {
                            Thread.Sleep(1000);
                        }
                    }
                }
            }

            else
            {
                break;
            }
        }

    }

Consider Wrapping your methods in a Task then you can easily use Task.WaitAny Method

var task1 = Task.Run(() => Method1() );
var task2 = Task.Run(() => Method2() );
var task3 = Task.Run(() => Method3() );
Task.WaitAny(task1, task2, task3);

note that tasks wrap exceptions so in case u done this and any exception happened in Methods 1,2,3 the catch block will never be executed :

 try
            {
                Task task1 = Task.Run(() => Method1());
                Task task2 = Task.Run(() => Method2());
                Task task3 = Task.Run(() => Method3());
                Task.WaitAny(task1, task2, task3);

            }
            catch (System.Exception)
            {    
                throw;
            }

but you case still get the status of the Task variable itself
