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 = 0;
            //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;
        }
