Question

This method adds something to db every 5 seconds.

I want to stop this process after 10 products added.

How can i stop this process?

public static  void AddMyProductToDB()
{
    Timer myTimer = new Timer(5000);
    myTimer.Start();
    if (!CountControl())
    {
        myTimer.Stop();
        myTimer.Enabled = false;
        myTimer.Dispose();
    }
    else
    {
        myTimer.Elapsed += new ElapsedEventHandler(MyWork);
        while (true) { }
    }
}

Answer 1

You have infinite loop which will block the code from being executed for the second time.

Also you seems to have to read this tutorial

OR use this code snippet

for (int i = 0; i < 5; i++)
{
    MyWork();
    System.Threading.Thread.Sleep(5000);
}
