return finally执行吗

 

using System;
class Test
{
    static void Main()
    {
        test();
    }
    public static void test()
    {
        try
        {
            Console.WriteLine("OK");
            string s = "we";
            int i = int.Parse(s);
            return;
        }
        catch
        {
            Console.WriteLine("catch");
        }
        finally
        {
            Console.WriteLine("finally");
        }    
    }
}

答案是执行.
什么时候执行? 以前看过有人解释后面找不到了
