How to read a data from text file in unity

Question

Can anybody help me out with giving the steps needed for reading data from the text file in unity and how can the script be added.

Answer 1

C# Version.

using System.IO;

void readTextFile(string file_path)
{
   StreamReader inp_stm = new StreamReader(file_path);

   while(!inp_stm.EndOfStream)
   {
       string inp_ln = inp_stm.ReadLine( );
       // Do Something with the input. 
   }

   inp_stm.Close( );  
}

EDIT: (Fixed an error on line 9; changed "stm.ReadLine();" to "inp_stm.ReadLine();")

There's a class named TextAssets which is used for text file reading. http://docs.unity3d.com/Manual/class-TextAsset.html Here you can find the supported file format.

So if you want to read the text file, the script would be like this:

class YourClassName : MonoBehaviour{
    public TextAsset textFile;     // drop your file here in inspector

    void Start(){
        string text = textFile.text;  //this is the content as string
        byte[] byteText = textFile.bytes;  //this is the content as byte array
    }
}

or you can read the text as resource like this:

TextAsset text = Resources.Load("YourFilePath") as TextAsset;

Answer 3

You can do this in the same way you would in .NET

string word = File.ReadAllText(txtFilePath);

This code snippet can be used in any location you wish then.

Answer 4

This code is working fine for me to read the content in the text file

import System.IO;

var filename = "data.txt";

function Start () {
    var source = new StreamReader(Application.dataPath + "/" + filename);
    var fileContents = source.ReadToEnd();
    source.Close();
    var lines = fileContents.Split("\n"[0]);
    for(line in lines) {
        print(line);
    }
}

We can use TextAsset data type to access text file content in Unity3D.

Try the following code,

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class Global : MonoBehaviour
{
    public TextAsset textFile;

    // Start is called before the first frame update
    void Start()
    {
        getFileContents();
    }

    // Update is called once per frame
    void Update()
    {
        
    }

    void getFileContents() {
        string data = textFile.text.Split('\n');
        for(line in data) {
            Debug.Log(line);
        }
    }
}
