POSystem.UnauthorizedAccessException when getting directories
text
Body
copied!<p>I am really new to C#, so I've been working on a small pet project.</p> <p>I've created a small program that compares the size of a directory with a given size. And if the directory is equal or larger, then it logs the path to that directory.</p> <pre><code>long size = Convert.ToInt32(Size) * 1024 * 1024; string[] directories = Directory.GetDirectories(path, "*", SearchOption.AllDirectories); //the error occurs on this line Array.Sort(directories); foreach (string name in directories) try { DirectoryInfo directory = new DirectoryInfo(name); long dir = directory.EnumerateFiles("*", SearchOption.AllDirectories).Sum(fi => fi.Length); if (dir >= ScanSize) Console.WriteLine(directory); } catch (UnauthorizedAccessException) { } </code></pre> <p>I should note that the input strings, and the <code>long size = Convert.ToInt32(Size)</code> come from the arguments in the <code>Main()</code></p> <p>I've read somewhere that I shouldn't use</p> <p><code>Directory.GetDirectories(ScanPath, "*", SearchOption.AllDirectories);</code></p> <p>since it'll get all the directories at once. But if I remove it, it only gets the directories in the given path, without any subdirectories. So I was told to apply recursion, but I found these fairly difficult. I read some things on <code>file.Attributes</code>, about hidden files, but I didn't know where to apply them.</p> <p>I am the administrator of the system and I plan to run this on the entire data drive. D:\ </p> <p>But in this case the error occurs when the program tries to access the trash can of the D:\ But even if it skips this specific location, the error still comes back at another inaccessible one.</p> <p>I'm hoping anyone here knows a good example or knows a website that explains this.</p>
