To use the Once class in your project:
var once = new Once();
var counter = 0;
for (int i = 0; i < 1000; i++)
{
// Despite this loop running 1000 times, the action will only be executed once.
once.Do(() => counter++);
}
Console.WriteLine(counter); // Outputs: 1- Ensures that a function or an action is executed only once, even in a multithreaded environment.
- Allows for exception handling in the Do method.
- Provides async support with the DoAsync method.
Please see the tests for more examples of how to use the Once class.
