#基础知识
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
- string path=@"X:\XXX\XX";
- DirectoryInfo root = new DirectoryInfo(path);
- FileInfo[] files=root.GetFiles();
3, 获得该文件夹下的子目录, 返回类型为 DirectoryInfo
- string path=@"X:\XXX\XX";
- DirectoryInfo root = new DirectoryInfo(path);
- DirctoryInfo[] dics=root.GetDirectories();
4, 获得文件夹名
- string path=@"X:\XXX\XX";
- DirectoryInfo root = new DirectoryInfo(path);
- string dicName=root.Name;
5, 获得文件夹完整的路径名
- string path=@"X:\XXX\XX";
- DirectoryInfo root = new DirectoryInfo(path);
- string dicName=root.FullName;
6, 获取文件的 Name 和 FullName
- string path=@"X:\XXX\XX";
- DirectoryInfo root = new DirectoryInfo(path);
- foreach (FileInfo f in root.GetFiles())
- {
- string name=f.Name;
- string fullName=f.FullName;
- }

# 只获取目录下一级的文件夹与文件
- String path = @"X:\xxx\xxx";
- // 第一种方法
- string[] files = Directory.GetFiles(path, "*.txt");
- foreach (string file in files)
- {
- Console.WriteLine(file);
- }
- // 第二种方法
- DirectoryInfo folder = new DirectoryInfo(path);
- foreach (FileInfo file in folder.GetFiles("*.txt"))
- {
- Console.WriteLine(file.FullName);
- }
