if..else的替换：

public static void Sample(string item)
{
System.Collections.Generic.Dictionary<string, Action> dic = new System.Collections.Generic.Dictionary<string, Action>(1);
dic.Add("0", () => { Console.WriteLine("0"); });
dic.Add("1", () => { Console.WriteLine("1"); });
dic.Add("2", () => { Console.WriteLine("2"); });
dic[item].Invoke();
}
