Getting all file names from a folder using C# [duplicate]

Question

This question already has an answer here:

• How to recursively list all the files in a directory in C#? 19 answers

I wanted to know if it is possible to get all the names of text files in a certain folder.

For example, I have a folder with the name Maps, and I would like to get the names of all the text files in that folder and add it to a list of strings.

Is it possible, and if so, how I can achieve this?

Answer 1

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;
}

Hope this will help...

Answer 2

using System.IO; //add this namespace also 

---

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

Answer 3

It depends on what you want to do.

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

This will bring back ALL the files in the specified directory

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

This will bring back ALL the files in the specified directory with a certain extension

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

This will bring back ALL the files in the specified directory AS WELL AS all subdirectories with a certain extension

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

Hope this helps

Answer 4

Does exactly what you want.

System.IO.Directory.GetFiles

Answer 5

Take a look at Directory.GetFiles Method (String, String) (MSDN).

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

Answer 6

http://msdn.microsoft.com/en-us/library/system.io.directory.getfiles.aspx

The System.IO namespace has loads of methods to help you with file operations. The

Directory.GetFiles() 

method returns an array of strings which represent the files in the target directory.

Answer 7

I would recommend you google 'Read objects in folder'. You might need to create a reader and a list and let the reader read all the object names in the folder and add them to the list in n loops.
