C#学习目录处理

目录获取和处理；

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

 public static double dirsize(DirectoryInfo d)
         {
             double size = ;
             //寻找当前目录的文件，并计算其大小
             FileInfo[] fis = d.GetFiles();
             foreach(FileInfo fi in fis)
             {
                 size += fi.Length;
             }
             //寻找当前目录下面的目录，并计算每个目录的大小
             DirectoryInfo[] dis = d.GetDirectories();
             foreach(DirectoryInfo di in dis)
             {
                 size += dirsize(di);
             }
             return size;
         }
