为了获取文件，C#提供了一个方法Directory.GetFiles
Directory.GetFiles返回所有文件的名称（包括它们的路径） ) 匹配指定的搜索模式，并可选择搜索子目录。
在下面的示例中，* 匹配该位置中的零个或多个字符。
SearchOption TopDirectoryOnly。仅搜索顶级目录
SearchOption AllDirectories .搜索所有顶级目录和子目录
FileInfo 获取文件长度、名称等信息
示例1 H2>
static void Main (string[] args) { string rootPath = @"C:UsersKoushikDesktopTestFolder"; var files = Directory.GetFiles(rootPath, "*.*", SearchOption.AllDirectories); foreach (string file in files) { Console.WriteLine(file); } Console.ReadLine ();}
输出
C:UsersKoushikDesktopTestFolderTestFolderMainTestFolderMain.txtC:UsersKoushikDesktopTestFolderTestFolderMain 1TestFolderMain1.txtC:UsersKoushikDesktopTestFolderTestFolderMain 2TestFolderMain2.txtC:UsersKoushikDesktopTestFolderTestFolderMain 2TestFolderMainSubDirectoryTestFolderSubDirectory.txt
示例 2
static void Main (string[] args) { string rootPath = @"C:UsersKoushikDesktopTestFolder"; var files = Directory.GetFiles(rootPath, "*.*", SearchOption.TopDirectoryOnly); foreach (string file in files) { Console.WriteLine(file); } Console.ReadLine ();}
输出
C:UsersKoushikDesktopTestFolderTopdirectory.txt
示例 3
static void Main (string[] args) { string rootPath = @"C:UsersKoushikDesktopTestFolder"; var files = Directory.GetFiles(rootPath, "*.*", SearchOption.AllDirectories); foreach (string file in files) { var info = new FileInfo(file); Console.WriteLine($"{ Path.GetFileName(file) }: { info.Length } bytes"); } Console.ReadLine ();}
输出
Topdirectory.txt: 0 bytesTestFolderMain.txt: 0 bytesTestFolderMain1.txt: 10 bytesTestFolderMain2.txt: 20 bytes
static void Main (string[] args) { string rootPath = @"C:UsersKoushikDesktopTestFolder"; var files = Directory.GetFiles(rootPath, "*.*", SearchOption.AllDirectories); foreach (string file in files) { Console.WriteLine(file); } Console.ReadLine ();}
