How in C# to execute a method in the "queue" once a second, and not more often?

Question

C++ / C#

I need, as soon as a certain event "Data has been updated" occurs - run the X method - "Dispatch updated data to clients".
But if the event is called, say, 50 times per second, there is no need to immediately run the X method that many times, creating a load.
Is it possible to somehow queue an event, and if there is a queue, run the X method, then execute only the most recent event?
For example, the 5th client connected. And now the 6th client connects immediately, that is, I have to immediately send the updated table of users of five clients (you can, of course, send that a certain client has connected, but now I want to send the entire table of clients online). According to the usual logic, a lot of messages will be sent, but if you make it so that the distribution method is blocked for sending, say for a second, as soon as it is completed and has a run counter. That is, for the next second, 20 attempts to send data came, but he is silent and then sends the actual data
. Option 1: There are 50 clients online. The 51st is connected. I send a 50+1 client a list of online clients. Connect 52nd - do the same.
Option 2: There are 50 clients online. The 51st is connected. I send everything. But then a couple of dozen people connect and I have to send everything out in the same way.
I want, if there has just been a distribution, not to send immediately, but to wait, say, a second and then, if there was a request to send the data, then send the table to the current time. Thus, all clients received data - albeit not instantly, but a second later, but I did not send very many times.
Well, something like this.
Maybe this is of course nonsense, it just became interesting how to implement this?

Answer 1

Delov, there is such a thing - a timer. If someone connects, messages are sent out and a timer starts until the timer finishes counting no new messages can be sent.

Answer 2

Here
is my idea:

1. Make It Yourself Method
   
2. Run it on a Thread
   
3. In this method write Thread.Sleep(1000)//1sec
   

Answer 3

Read about the 4th point, maybe it will be useful to you.
