最近在寫一個讓程式自動更新的功能實際上就只是進行檔案的複製貼上而已但是放在單一執行緒下可以正常運作多執行緒下就會直接讓程式結束不知道是哪裡出問題請大家幫我看看 CODE 如下 backgroundWorker1.RunWorkerAsync(); private void backgroundWorker1_DoWork(object sender, DoWorkEventArgs e) { DirectoryCopy(g_strCopyLocal, g_strCopyBackup, true); DirectoryCopy(g_strCopyServer, g_strCopyLocal, true); } private static void DirectoryCopy(string sourceDirName, string destDirName, bool copySubDirs) { // Get the subdirectories for the specified directory. DirectoryInfo dir = new DirectoryInfo(sourceDirName); DirectoryInfo[] dirs = dir.GetDirectories(); if (!dir.Exists) { throw new DirectoryNotFoundException( "Source directory does not exist or could not be found: " + sourceDirName); } // If the destination directory doesn't exist, create it. if (!Directory.Exists(destDirName)) { Directory.CreateDirectory(destDirName); } // Get the files in the directory and copy them to the new location. FileInfo[] files = dir.GetFiles(); foreach (FileInfo file in files) { try { string temppath = Path.Combine(destDirName, file.Name); file.CopyTo(temppath, true); } catch { } } // If copying subdirectories, copy them and their contents to new location. if (copySubDirs) { foreach (DirectoryInfo subdir in dirs) { if (subdir.Name != "UpGrade" || subdir.Name != "CheakVersion") { string temppath = Path.Combine(destDirName, subdir.Name); DirectoryCopy(subdir.FullName, temppath, copySubDirs); } } } } 請大家能給我一些方向 -- Sent from my Misaka 10032 -- ※ 發信站: 批踢踢實業坊(ptt.cc), 來自: 210.71.170.97 ※ 文章網址: https://www.ptt.cc/bbs/C_Sharp/M.1428384508.A.293.html
