取消文件夾下的子文件夾和文件的只讀屬性

private void UnsetReadOnly(string dirPath)
{//http://bbs.csdn.net/topics/380233913
string[] dirPathes = Directory.GetDirectories(dirPath, "*.*", SearchOption.AllDirectories);
string[] filePathes = Directory.GetFiles(dirPath, "*.*", SearchOption.AllDirectories);
foreach (var dp in dirPathes)
{
DirectoryInfo dir = new DirectoryInfo(dirPath);
dir.Attributes = FileAttributes.Normal & FileAttributes.Directory;
}
foreach (var fp in filePathes)
{
File.SetAttributes(fp, System.IO.FileAttributes.Normal);
}
}

 

用ICSharpZipLib解壓,如果目標文件夾里的文件為只讀屬性會導致解壓失敗:UnauthorizedAccessException: Access to the path is denied.

使用如上代碼取消文件的只讀屬性后解決.(只設置文件夾的Attributes為非只讀沒作用,里面的文件還是只讀)
