本文實例講述了C#實現安全刪除文件目錄的方法。分享給大家供大家參考。具體分析如下：
1. 創建文件夾 (簡單，沒多考慮)
2. 刪除所建文件夾：為防止刪除過程中有其他進程引用該文件夾中文件，增加了對此意外情況的考慮。
在本例中，若刪除過程中被其他進程引用，等待并循環5次嘗試再次刪除操作。長時間無法被刪除，則刪除文件目錄失敗
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) + "http://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(); } }}希望本文所述對大家的C#程序設計有所幫助。
