I have a list:

private List<OutlinedObject> allObjects = new List<OutlinedObject>();

that contains elements with a public method

Pulse(string a, int b) {}

and I want to call methods from all elements in array not iteratively. I think it should be like this, but it doesn't work:

allObjects.Pulse("prop", 10);

Can I do this in C#? Is it possible to do this without using delegates?

If I understood you correctly you can use List<T>.ForEach (which actually just iterates the collection executing corresponding action sequentially):

allObjects.ForEach(i => i.Pulse("prop", 10));

If you want to run them in parallel you can use AsParallel (use WithDegreeOfParallelism to control number of parallel executions):

allObjects.AsParallel().ForAll(i => i.Pulse("prop", 10))
