本文實例講述了C#完成平安刪除文件目次的辦法。分享給年夜家供年夜家參考。詳細剖析以下:
1. 創立文件夾 (簡略,沒多斟酌)
2. 刪除所建文件夾:為避免刪除進程中有其他過程援用該文件夾中文件,增長了對此不測情形的斟酌。
在本例中,若刪除進程中被其他過程援用,期待並輪回5次測驗考試再次刪除操作。長時光沒法被刪除,則刪除文件目次掉敗
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) + "\\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(); } } }
願望本文所述對年夜家的C#法式設計有所贊助。
