从项目中存在的文件夹中读取文件

Question

I have a C# project (Windows Console Application). I have created a folder named Data inside project. There are two text files inside folder Data.

How can I read the text files from "Data" folder. I tried below things.

string[] files = File.ReadAllLines(@"Data\Names.txt")

It is thowing error that file not found.

I have checked some Stackoverflow answers posted before and none of then are working for me.

How can I proceed? Thanks!

Answer 1

below code should work:

string path = Path.Combine(Path.GetDirectoryName(Assembly.GetExecutingAssembly().Location), @"Data\Names.txt");
string[] files = File.ReadAllLines(path);

Answer 2

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" )

Answer 3

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");

Answer 5

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

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

Answer 6

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")

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
