Any chances to imitate times() Ruby method in C#?

Question

Every time I need to do something N times inside an algorithm using C# I write this code

for (int i = 0; i < N; i++)
{
    ...
}

Studying Ruby I have learned about method times() which can be used with the same semantics like this

N.times do
    ...
end

Code fragment in C# looks more complex and we should declare useless variable i.

I tried to write extension method which returns IEnumerable, but I am not satisfied with the result because again I have to declare a cycle variable i.

public static class IntExtender
{
    public static IEnumerable Times(this int times)
    {
        for (int i = 0; i < times; i++)
            yield return true;
    }
}

...

foreach (var i in 5.Times())
{
    ...
}

Is it possible using some new C# 3.0 language features to make N times cycle more elegant?

A slightly briefer version of cvk's answer:

public static class Extensions
{
    public static void Times(this int count, Action action)
    {
        for (int i=0; i < count; i++)
        {
             action();
        }
    }

    public static void Times(this int count, Action<int> action)
    {
        for (int i=0; i < count; i++)
        {
             action(i);
        }
    }
}

Use:

5.Times(() => Console.WriteLine("Hi"));
5.Times(i => Console.WriteLine("Index: {0}", i));
