I have directory that contains nearly 14,000,000 audio samples in *.wav format. All plain storage, no subdirectories. I want to loop through the files, but when I use DirectoryInfo.GetFiles() on that folder the whole application freezes for minutes! Can this be done another way? Perhaps read 1000, process them, then take next 1000 and so on? Haris Hasan Have you tried EnumerateFiles method of DirectoryInfo class? As MSDN Says The EnumerateFiles and GetFiles methods differ as follows: When you use EnumerateFiles , you can start enumerating the collection of FileInfo objects before the whole

问题 This question already has answers here : Closed 7 years ago . Possible Duplicate: How to get only filenames within a directory using c#? Using C#, I want to get the list of files in a folder. My goal: ["file1.txt", "file2.txt"] So I wrote this: string[] files = Directory.GetFiles(dir); Unfortunately, I get this output: ["C:\\dir\\file1.txt", "C:\\dir\\file2.txt"] I could strip the unwanted "C:\dir\" part afterward, but is there a more elegant solution? 回答1: You can use System.IO.Path

Directory.GetFiles of certain extension

Is there a way to simplify this linq expression, or is there a better way of doing this? Directory.GetFiles(dir, "*.*", SearchOption.AllDirectories) .Where(s => s.EndsWith(".jpg", StringComparison.OrdinalIgnoreCase) || s.EndsWith(".gif", StringComparison.OrdinalIgnoreCase) || s.EndsWith(".png", StringComparison.OrdinalIgnoreCase) || ...); Basically I want to return all files of a certain extension. Unfortunately, this method isn't very flexible. I'd rather be able to add extensions to a list and have Directory.GetFiles return those extensions. Is that possible? dasblinkenlight If you would

Possible Duplicate: Can you call Directory.GetFiles() with multiple filters? How do you filter on more than one extension? 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) {

Ignore folders/files when Directory.GetFiles() is denied access

问题 I am trying to display a list of all files found in the selected directory (and optionally any subdirectories). The problem I am having is that when the GetFiles() method comes across a folder that it cannot access, it throws an exception and the process stops. How do I ignore this exception (and ignore the protected folder/file) and continue adding accessible files to the list? try { if (cbSubFolders.Checked == false) { string[] files = Directory.GetFiles(folderBrowserDialog1.SelectedPath);
