Read Files from a Folder Present in Project

it depends where is your Data folder

To get the directory where the .exe file is:

AppDomain.CurrentDomain.BaseDirectory

To get the current directory:

Environment.CurrentDirectory

Then you can concatenate your directory path (@"\Data\Names.txt")

If you need to get all the files in the folder named 'Data', just code it as below

string[] Documents = System.IO.Directory.GetFiles("../../Data/");

Now the 'Documents' consists of array of complete object name of two text files in the 'Data' folder 'Data'.

I have a C# project (Windows Console Application). I have created a folder named Images inside project. There is one ico file called MyIcon.ico. I accessed MyIcon.ico inside Images folder like below.

this.Icon = new Icon(@"../../Images/MyIcon.ico");

Copy Always to output directory is set then try the following:

 Directory.SetCurrentDirectory(AppDomain.CurrentDomain.BaseDirectory);
 String Root = Directory.GetCurrentDirectory();

This was helpful for me, if you use the

var dir = Directory.GetCurrentDirectory()

the path fill be beyond the current folder, it will incluide this path \bin\debug What I recommend you, is that you can use the

string dir = Directory.GetParent(Directory.GetCurrentDirectory()).Parent.Parent.FullName

then print the dir value and verify the path is giving you

For Xamarin.iOS you can use the following code to get contents of the file if file exists.

var documents = Environment.GetFolderPath(Environment.SpecialFolder.MyDocuments);
var filename = Path.Combine(documents, "xyz.json");
if (File.Exists(filename))
{
var text =System.IO.File.ReadAllText(filename);
}

Use this Code for read all files in folder and sub-folders also

class Program
{
    static void Main(string[] args)
    {

        getfiles get = new getfiles();
        List<string> files =  get.GetAllFiles(@"D:\Document");

        foreach(string f in files)
        {
            Console.WriteLine(f);
        }


        Console.Read();
    }


}

class getfiles
{
    public List<string> GetAllFiles(string sDirt)
    {
        List<string> files = new List<string>();

        try
        {
            foreach (string file in Directory.GetFiles(sDirt))
            {
                files.Add(file);
            }
            foreach (string fl in Directory.GetDirectories(sDirt))
            {
                files.AddRange(GetAllFiles(fl));
            }
        }
        catch (Exception ex)
        {

            Console.WriteLine(ex.Message);
        }



        return files;
    }
}

string myFile= File.ReadAllLines(Application.StartupPath.ToString() + @"..\..\..\Data\myTxtFile.txt")
