C#学习目录处理

目录获取和处理；

 1 string path = ".";//表明要在当前所在的目录
 2             //先定义目录信息变量
 3             DirectoryInfo dir = new DirectoryInfo(path);
 4             foreach(FileInfo ld in dir.GetFiles())
 5             {
 6                 string name = ld.Name;
 7                 long size = ld.Length;
 8                 DateTime time = ld.CreationTime;
 9                 Console.WriteLine("{0,-12:N0}{1,-20:g}{2}",size,name,time);
10             }
11             //制定目录名称
12             string pa = "E:/Cprogram";
13             DirectoryInfo din = new DirectoryInfo(pa);
14             Console.WriteLine(dirsize(din).ToString());
15             Console.ReadKey();

 1 public static double dirsize(DirectoryInfo d)
 2         {
 3             double size = 0;
 4             //寻找当前目录的文件，并计算其大小
 5             FileInfo[] fis = d.GetFiles();
 6             foreach(FileInfo fi in fis)
 7             {
 8                 size += fi.Length;
 9             }
10             //寻找当前目录下面的目录，并计算每个目录的大小
11             DirectoryInfo[] dis = d.GetDirectories();
12             foreach(DirectoryInfo di in dis)
13             {
14                 size += dirsize(di);
15             }
16             return size;
17         }

What I don't dare to say is I can't!
