本文实例讲述了C#实现安全删除文件目录的方法。分享给大家供大家参考。具体分析如下：

1. 创建文件夹 (简单，没多考虑)

2. 删除所建文件夹：为防止删除过程中有其他进程引用该文件夹中文件，增加了对此意外情况的考虑。

在本例中，若删除过程中被其他进程引用，等待并循环5次尝试再次删除操作。长时间无法被删除，则删除文件目录失败

using System;using System.IO;namespace Retry{ class Program { static void Main(string[] args) { DirectoryInfo dirInfo = Directory.CreateDirectory(@"C:\TestDir"); string folderName = System.Environment.GetFolderPath(Environment.SpecialFolder.ApplicationData) + "\\TestDir"; if (!Directory.Exists(folderName)) { Directory.CreateDirectory(folderName); Console.WriteLine("{0} created! ",folderName); } int retryTimes = 1; do { if (Directory.Exists(folderName)) { try { Console.WriteLine("Tring to delete file the {0} time.",retryTimes); Directory.Delete(folderName, true); Console.WriteLine("Deleting file successfully."); break; } catch (IOException ex) { Console.WriteLine("Exception! ", ex.ToString()); Console.WriteLine("Sleep 5 seconds and retry."); System.Threading.Thread.Sleep(5000); retryTimes++; } } else { Console.WriteLine("Delete folder successfully"); break; } } while (retryTimes <= 5); if (Directory.Exists(folderName)) Console.WriteLine("Deleting folder failed."); Console.WriteLine("Done"); Console.ReadKey(); } }}

希望本文所述对大家的C#程序设计有所帮助。
