PODirectory.GetFiles keeping the last access time
text
Body
copied!<p>It appears that Directory.GetFiles() in C# modifies the Last access date of a file. I've googled for hours and can't seem to find a work around for this issue. Is there anyway to keep all the MAC (Modified, Accessed, Created) attributes of a file? I'm using Directory.GetDirectories(), Directory.GetFiles(), and FileInfo.</p> <p>Also, the fi.LastAccessTime is giving strange results -- the date is correct, however, the time is off by 2 minutes, or a few hours.</p> <pre><code>Time of function execution: 10/31/2008 8:35 AM Program Shows As Last Access Time 0_PDFIndex.html - 10/31/2008 8:17:24 AM AdvancedArithmetic.pdf - 10/31/2008 8:31:05 AM AdvancedControlStructures.pdf - 10/30/2008 1:18:00 PM AoAIX.pdf - 10/30/2008 1:18:00 PM AoATOC.pdf - 10/30/2008 12:29:51 PM AoATOC2.pdf - 10/30/2008 1:18:00 PM Actual Last Access Time 0_PDFIndex.html - 10/31/2008 8:17 AM AdvancedArithmetic.pdf - 10/30/2008 12:29 PM AdvancedControlStructures.pdf - 10/30/2008 12:29 PM AoAIX.pdf - 10/30/2008 12:29 PM AoATOC.pdf - 10/30/2008 12:29 PM AoATOC2.pdf - 10/30/2008 12:29 PM </code></pre> <p>Below is the method I'm using. If you require more information, please let me know.</p> <p>Thanks!</p> <pre><code>public void PopulateTreeView(string directoryValue, ref TreeNode parentNode) { string[] directoryArray = Directory.GetDirectories(directoryValue); string[] fileArray = Directory.GetFiles(directoryValue, "*.*", SearchOption.AllDirectories); try { #region Directories if (directoryArray.Length != 0) { foreach (string directory in directoryArray) { DirectoryInfo di = new DirectoryInfo(directory); TreeNode dirNode = parentNode.Nodes.Add(di.Name); FileNode fn = new FileNode(); fn.bIsDir = true; fn.dir = di; dirNode.Tag = fn; PopulateTreeView(directory, ref dirNode); Application.DoEvents(); } } #endregion #region Files if (fileArray.Length != 0) { foreach (string file in fileArray) { FileInfo fi = new FileInfo(file); TreeNode fileNode = parentNode.Nodes.Add(fi.Name); FileNode fn = new FileNode(); fn.bIsDir = false; fn.file = fi; fileNode.Tag = fn; fileNode.ImageIndex = 1; Console.WriteLine(fi.Name + " - " + fi.LastAccessTime); } } #endregion } catch (UnauthorizedAccessException) { parentNode.Nodes.Add("Access denied"); } catch (Exception ex) { MessageBox.Show(ex.ToString()); } finally { Application.DoEvents(); } } </code></pre> <hr> <p>i know the differences between the attributes. What i need is for the file to remain exactly the same all attributes and meta-data, as if my program never touched the file; this includes the last access date.</p>
