Is there a way to query running threads inside your C# application by thread name?

If you've done something like

Thread logSend = new Thread(() => senddat.SendLoggedData());
logSend.Priority = ThreadPriority.AboveNormal;
logSend.Name = "BackLogThread";
logSend.IsBackground = false;
logSend.Start();

Are you able to simply verify at a later point, from another thread, that there IS a thread with the name "BackLogThread" currently running?

I don't want to do anything to the thread, I just want to query the threads inside my application to see if there is one with that particular name.

Edit:

As far as the other question that was asked related to this one, that solution is viable, but it is a little much for what I am asking. The person in that example wants to know a lot about the thread like their priority etc. for logging information. I want at most a true to return if there's any thread anywhere with the name "BackLogThread" running.

As far as I know this is not possible because there's no way to get all managed threads in C#. But you can manually add them to a pool and retrieve them later.

The pool/registry can look like this:

public class ThreadRegistry
{
   private static ThreadRegistry instance;
   private readonly object syncRoot = new object();
   private readonly IDictionary<string, Thread> threads = new Dictionary<string, Thread>();

   private ThreadRegistry()
   {
   }

   public static ThreadRegistry Instance => instance ?? (instance = new ThreadRegistry());

   public Thread this[string name]
   {
      get
      {
         lock (this.syncRoot)
         {
            return this.threads[name];
         }
      }
   }

   public void Register(Thread thread)
   {
      lock (this.syncRoot)
      {
         this.threads.Add(thread.Name, thread);
      }
   }

   public bool ThreadExists(string name)
   {
      lock(this.syncRoot)
      {
         return this.threads.ContainsKey(name);
      }
   }
}
