Using C# to get all file names from a folder [duplicate]

Category: c#

Tag: , , ,

Problem

I’m curious if it’s feasible to acquire a list of all the names of text files in a specific folder.

For example, I have a folder called Maps, and I’d like to extract the names of all the text files in that folder and add them to a string list.

Is this possible, and if so, how do I go about doing it?

Solution #1

using System.IO;

DirectoryInfo d = new DirectoryInfo(@"D:\Test"); //Assuming Test is your Folder

FileInfo[] Files = d.GetFiles("*.txt"); //Getting Text files
string str = "";

foreach(FileInfo file in Files )
{
  str = str + ", " + file.Name;
}

using System.IO; //add this namespace also 

string[] filePaths = Directory.GetFiles(@"c:\Maps\", "*.txt",
                                         SearchOption.TopDirectoryOnly);

It is up to you to decide what you want to do.

ref: http://www.csharp-examples.net/get-files-from-directory/

All of the files in the chosen directory will be restored.

string[] fileArray = Directory.GetFiles(@"c:\Dir\");

This will return ALL files with a specific extension in the supplied directory.

string[] fileArray = Directory.GetFiles(@"c:\Dir\", "*.jpg");

This will restore ALL files in the chosen directory, as well as all subdirectories with the specified extension.

string[] fileArray = Directory.GetFiles(@"c:\Dir\", "*.jpg", SearchOption.AllDirectories);

Hope this helps

Does precisely what you’ve asked for.

System.IO.Directory.GetFiles

Take a peek at the Directory section. Method GetFiles (String, String) (MSDN).

This method returns an array of filenames including all of the files.
