Let a thread wait for n number of pulses in C#

Let a thread wait for n number of pulses in C#

In C#, you can use the AutoResetEvent or ManualResetEvent classes to synchronize threads based on pulses. Here's an example of how to use AutoResetEvent to let a thread wait for n number of pulses:

using System.Threading; class Program { static AutoResetEvent _autoResetEvent = new AutoResetEvent(false); static void Main(string[] args) { int numberOfPulsesToWaitFor = 3; int pulsesReceived = 0; Thread thread = new Thread(() => { while (pulsesReceived < numberOfPulsesToWaitFor) { _autoResetEvent.WaitOne(); pulsesReceived++; } Console.WriteLine("Received {0} pulses", pulsesReceived); }); thread.Start(); for (int i = 0; i < numberOfPulsesToWaitFor; i++) { // Simulate a pulse by calling Set on the AutoResetEvent _autoResetEvent.Set(); Thread.Sleep(1000); } } }

In this example, we create an AutoResetEvent object called _autoResetEvent and set its initial state to false. We then start a new thread that waits for n number of pulses before continuing.

In the main thread, we simulate the pulses by calling Set on the _autoResetEvent object and waiting for one second between each pulse. When the thread has received the required number of pulses, it prints out a message.

Note that in this example, we're using a loop to simulate the pulses. In a real application, you would probably have some other mechanism for generating the pulses, such as an event or a message queue.
