fileinfo

I have a List which is being returned from a WCF service ,for List of files on Server. Which i am later using to populate the TreeView in my Client Application I need the list to be in naturally sorted order. For ex : I have a list something like List-1 , and my expected result is List-2 but i get List-3 as my output.(refer list given below) List-1 List-2 List-3 abc.jpg abc.jpg abc.jpg abc10.jpg abc10.jpg abc10.jpg abc100.jpg abc97.jpg abc100.jpg abc98.jpg abc98.jpg abc101.jpg abc97.jpg abc100.jpg abc102.jpg abc102.jpg abc101.jpg abc97.jpg abc101.jpg abc102.jpg abc98.jpg So far i have looked

I am creating a backup application where c# scans a directory. Before I use to have something like this in order to get all the files and subfiles in a directory: DirectoryInfo di = new DirectoryInfo("A:\\"); var directories= di.GetFiles("*", SearchOption.AllDirectories); foreach (FileInfo d in directories) { //Add files to a list so that later they can be compared to see if each file // needs to be copid or not } The only problem with that is that sometimes a file could not be accessed and I get several errors. an example of an error that I get is: As a result I created a recursive method

When I call FileInfo(path).LastAccessTime or FileInfo(path).LastWriteTime on a file that is in the process of being written it returns the time that the file was created, not the last time it was written to (ie. now). Is there a way to get this information? Edit: To all the responses so far. I hadn't tried Refresh() but that does not do it either. I am returned the time that the file was started to be written to. The same goes for the static method, and creating a new instance of FileInfo . Codymanix might have the answer, but I'm not running Windows Server (using Windows 7), and I don't know

I've tried: FileInfo[] Files = dinfo.GetFiles("*.jpg;*.tiff;*.bmp"); FileInfo[] Files = dinfo.GetFiles("*.jpg,*.tiff,*.bmp"); Cheng Chen Why not create an extension method? That's more readable. public static IEnumerable<FileInfo> GetFilesByExtensions(this DirectoryInfo dir, params string[] extensions) { if (extensions == null) throw new ArgumentNullException("extensions"); IEnumerable<FileInfo> files = Enumerable.Empty<FileInfo>(); foreach(string ext in extensions) {
