C#中对文件夹操作需要用到Directory Class。其中提供了创建、删除、移动、枚举等静态方法。该类不能被继承。
以下代码实现了创建文件夹。
| if (!Directory.Exists(sPath)) { Directory.CreateDirectory(sPath); } |
以下是MSDN上Directory Class的Sample code。

以下代码首先检查指定的文件夹是否存在，若存在则删除之，否则创建之。接下来移动文件夹，在其中创建文件并统计文件夹中文件数目。
| using System; using System.IO; class Test { public static void Main() { // Specify the directories you want to manipulate. string path = @"c:\MyDir"; string target = @"c:\TestDir"; try { // Determine whether the directory exists. if (!Directory.Exists(path)) { // Create the directory it does not exist. Directory.CreateDirectory(path); } if (Directory.Exists(target)) { // Delete the target to ensure it is not there. Directory.Delete(target, true); } // Move the directory. Directory.Move(path, target); // Create a file in the directory. File.CreateText(target + @"\myfile.txt"); // Count the files in the target directory. Console.WriteLine("The number of files in {0} is {1}", target, Directory.GetFiles(target).Length); } catch (Exception e) { Console.WriteLine("The process failed: {0}", e.ToString()); } finally {} } } |
