谁帮我看一下，为什么我不能输出全部的控制台信息，只能输出一部分

不明白意思，你这个不就是输出C:/123目录下的所有文件数(包括子文件夹内的)和文件夹数吗？

因为你每次递推调用ListDirectoriesAndFiles()时，都会新建一个

List<string> list = new List<string>();

然后你又

StreamWriter sw = new StreamWriter(@"C:\new.txt")

每次都新建一个new.txt

要么你就用全局的list，要么就用追加的方式打开文件

StreamWriter sw = new StreamWriter(@"C:\new.txt", true)

额 如果以追加方式也不好啊 那不是我每次运行项目，文件中就追加一次啊 还是相同的内容。。。。。
