FileInfo[] fis = d.GetFiles(); foreach (FileInfo fi in fis) { Size += fi.Length; } // Add subdirectory sizes. DirectoryInfo[] dis = d.GetDirectories(); foreach (DirectoryInfo di in dis) { Size += DirSize(di); } return(Size); } 应用示例: // The following example calculates the size of a directory // and its subdirectories, if any, and displays the total size // in bytes. using System; using System.IO; public class ShowDirSize { public static long DirSize(DirectoryInfo d) { long Size = 0; // Add file sizes. FileInfo[] fis = d.GetFiles(); foreach (FileInfo fi in fis) { Size += fi.Length; } // Add subdirectory sizes. DirectoryInfo[] dis = d.GetDirectories(); foreach (DirectoryInfo di in dis) { Size += DirSize(di); } return(Size); } public static void Main(string[] args) { if (args.Length != 1) { Console.WriteLine("You must provide a directory argument at the command line."); } else { DirectoryInfo d = new DirectoryInfo(args[0]); Console.WriteLine("The size of {0} and its subdirectories is {1} bytes.", d, DirSize(d)); } } }
