Winphone 沒有直接刪除文件夾的接口(因為文件夾不為空是刪除不了的),所以要自己實現 public static void DeleteDirectoryRecursively(this IsolatedStorageFile storageFile, String dirName){ String pattern = dirName + @"\*"; String[] files = storageFile.GetFileNames(pattern); foreach (var fName in files) { storageFile.DeleteFile(Path.Combine(dirName, fName)); } String[] dirs = storageFile.GetDirectoryNames(pattern); foreach (var dName in dirs) { DeleteDirectoryRecursively(storageFile, Path.Combine(dirName, dName)); } storageFile.DeleteDirectory(dirName);}
