Method looping without using / foreach / while

Is there a way to call a method / lines of code several times without using a for / foreach / while loop?

For example, if I should use for a loop:

int numberOfIterations = 6;
for(int i = 0; i < numberOfIterations; i++)
{
   DoSomething();
   SomeProperty = true;
}

The lines of code that I call do not use "i", and, in my opinion, the whole loop declaration hides what I am trying to do. This is the same for foreach.

I was wondering if there is a loop that I can use that looks something like this:

do(6)
{
   DoSomething();
   SomeProperty = true;
}

It is clear that I just want to execute this code 6 times, and there is no noise associated with creating the index and adding 1 to some arbitrary variable.

As a training exercise, I wrote a static class and method:

Do.Multiple(int iterations, Action action)

What works, but is very much appreciated on an ambitious scale, and I'm sure my colleagues do not approve.

How about do .... before or if ... then

Use the counter inside the loop and run it until it reaches 6.

Or an if-then statement using a counter. If your value is 6, exit the loop.

I am not a programmer guru, but if you have an action that needs to be performed a certain number of times, a counter will be needed somewhere, regardless of whether it is a function of your loop or if it is created using a counter.
