Create multiple threads and wait all of them to complete

Question

How can I create multiple threads and wait for all of them to complete?

Answer 1

I've made a very simple extension method to wait for all threads of a collection:

using System.Collections.Generic;
using System.Threading;

namespace Extensions
{
    public static class ThreadExtension
    {
        public static void WaitAll(this IEnumerable threads)
        {
            if(threads!=null)
            {
                foreach(Thread thread in threads)
                { thread.Join(); }
            }
        }
    }
}

Then you simply call:

List threads=new List();
// Add your threads to this collection
threads.WaitAll();
