Is there an elegant way to repeat an action?

Question

In C#, using .NET Framework 4, is there an elegant way to repeat the same action a determined number of times? For example, instead of:

int repeat = 10;
for          


        

Answer 1

Like this?

using System.Linq;

Enumerable.Range(0, 10).ForEach(arg => toRepeat());

This will execute your method 10 times.

[Edit]

I am so used to having ForEach extension method on Enumerable, that I forgot it is not part of FCL.

public static void ForEach(this IEnumerable source, Action action)
{
    foreach (var item in source)
        action(item);
}

Here is what you can do without ForEach extension method:

Enumerable.Range(0, 10).ToList().ForEach(arg => toRepeat());

I think that the most elegant solution is to implement reusable method:

public static void RepeatAction(int repeatCount, Action action)
{
    for (int i = 0; i < repeatCount; i++)
        action();
}

Usage:

RepeatAction(10, () => { Console.WriteLine("Hello World."); });
