How to declare multiple variables with almost the same name

Question

I want to use multiple BackgroundWorkers for handling clients in a chat server (C#). But I don't know how to declare the multiple BackgroundWorkers. One backgroundworker for each client. I thought that maybe there is a way to declare them like this:

for(int counter=0; ; counter++) {
  BackgroundWorker bw_counter=new BackgroundWorker();
  bw_counter.RunWorkerAsync();
}

I want to replace "counter" in "bw_counter" with the actual value of "int counter". I don't know how to do this. Some people that have ideas?

I searched for a way to get it working but I couldn't thind a thread on SO that solves my problem.

What you are trying to do is pretty much the definition of an array (or IList, at the very least).

var my_workers = new BackgroundWorker[counter];

Now you can refer to them by number:

my_workers[0] = new BackgroundWorker();
my_workers[0].RunWorkerAsync();

A simple way to create the array using your original code:

var workers = Enumerable.Range(0, counter)
    .Select(_ => {
        var bw = new BackgroundWorker();
        bw.RunWorkerAsync();
        return bw; })
    .ToArray();
