1、获得当前运行程序的路径
1 string rootPath = Directory.GetCurrentDirectory();2、获得该文件夹下的文件，返回类型为FileInfo
1 string path=@"X:\XXX\XX"; 2 DirectoryInfo root = new DirectoryInfo(path); 3 FileInfo[] files=root.GetFiles();3、获得该文件夹下的子目录，返回类型为DirectoryInfo
1 string path=@"X:\XXX\XX"; 2 DirectoryInfo root = new DirectoryInfo(path); 3 DirctoryInfo[] dics=root.GetDirectories();4、获得文件夹名
1 string path=@"X:\XXX\XX"; 2 DirectoryInfo root = new DirectoryInfo(path); 3 string dicName=root.Name;5、获得文件夹完整的路径名
1 string path=@"X:\XXX\XX"; 2 DirectoryInfo root = new DirectoryInfo(path); 3 string dicName=root.FullName;6、获取文件的Name和FullName
1 string path=@"X:\XXX\XX"; 2 DirectoryInfo root = new DirectoryInfo(path); 3 foreach (FileInfo f in root.GetFiles()) 4 { 5 string name=f.Name; 6 string fullName=f.FullName; 7 }
