c#闭包使用方法示例

代码简单，直接上代码了

private static void before()
        {
            action[] actions = new action[10];

            for (var i = 0; i < actions.length; i++)
            {
                actions[i] = () =>
                {
                    console.writeline(i);
                };
            }

            foreach (var item in actions)
            {
                item();
            }
        }
