Some exception error when delete folders

1.some file been opened in other program 2.file property is readonly etc.

by the way, I fixed those issues, how can i commit it?

my Soluation,is add this method in fileutility ,then replace the directory.delete: public static void DeleteDirectory(string varDirePath,bool varRecursive) { string[] tempDirs = Directory.GetDirectories(varDirePath); string[] tempFiles = Directory.GetFiles(varDirePath); foreach (var tempDir in tempDirs) { File.SetAttributes(tempDir, FileAttributes.Normal); } foreach (var tempFile in tempFiles) { File.SetAttributes(tempFile, FileAttributes.Normal); File.Delete(tempFile); } File.SetAttributes(varDirePath, FileAttributes.Normal); Directory.Delete(varDirePath, varRecursive); }
