如何使用 C# 列出目录中的所有可用文件？

//creating a DirectoryInfo object
DirectoryInfo mydir = new DirectoryInfo(@"d:\amit");

FileInfo [] f = mydir.GetFiles();

using System;
using System.IO;

namespace Demo {
   class Program {
      static void Main(string[] args) {
         //creating a DirectoryInfo object
         DirectoryInfo mydir = new DirectoryInfo(@"d:\amit");

         // getting the files in the directory, their names and size
         FileInfo [] f = mydir.GetFiles();

         foreach (FileInfo file in f) {
            Console.WriteLine("File Name: {0} Size: {1}", file.Name, file.Length);
         }
         Console.ReadKey();
      }
   }
}
