首先，使用 DirectoryInfo 对象 -
//creating a DirectoryInfo object DirectoryInfo mydir = new DirectoryInfo(@"d:\amit");
现在，使用 GetFiles() 方法获取所有文件 -
FileInfo [] f = mydir.GetFiles();
要获取目录中的文件列表，请尝试运行以下代码 -
示例
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();
}
}
}
