Wait for a while without blocking main thread

Question

I wish my method to wait about 500 ms and then check if some flag has changed. How to complete this without blocking the rest of my application?

Answer 1

Using a timer should do the trick

if you need to use a thread then here is an example

void Main()
{
    System.Threading.Thread check= new System.Threading.Thread(CheckMethod);
    check.Start();
}

private void CheckMethod()
{
     //Code
     Thread.Sleep(500);
}
