If Statement - Check if two Text Class have the same text

Still learning here...

I've been able to develop a script I'm working on but I've hit a bit of a snag. I have two public classes:

Code (CSharp):

1.  
2.     public Text CurrentText = null;
3.     public Text LatestText = null;
4.     void Start()
5.     {
6.         CurrentText.text = System.IO.File.ReadAllText(@"C:\CurrentVersion.txt");
7.         LatestText.text = System.IO.File.ReadAllText(@"C:\LatestVersion.txt");
8.     }
9.  

I'm trying to create an if statement that compares these two text files to see if the information in both files is identical or not. However using this:

Code (CSharp):

1. if (CurrentText == LatestText)

while this doesn't produce any issues in the Console, from the reading I've done, because using text - this current if statement would only work for numerical values.

How would I write the if statement to compare two texts?

 

Perhaps it is String.CompareTo() you seek.

if (CurrentText.text.CompareTo(LatestText.text) == 0)

That statement will return true if the two strings are the same.

Edit:

Apparently it's bad form to use CompareTo(), although I think it works. You should actually use String.Equals():

if (CurrentText.text.Equals(LatestText.text))

 

Damn, that was a fast response - thanks!

So I replaced the if statement I had with the one you suggested. To tell if the statement would work - I'd have one of the texts change color... aaaand.... no - didn't work

Posted the full script here, it's probably something I've done...

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4. using UnityEngine.UI;
5. using System.IO;
6.  
7. public class scriptVersionText : MonoBehaviour
8.  
9. {
10.     public Text CurrentText = null;
11.     public Text LatestText = null;
12.  
13.     void Start()
14.     {
15.         Checker();
16.         CurrentText.text = System.IO.File.ReadAllText(@"C:\CurrentVersion.txt");
17.         LatestText.text = System.IO.File.ReadAllText(@"C:\LatestVersion.txt");
18.     }
19.  
20.     void Checker()
21.     {
22.  
23.         if (CurrentText.text.CompareTo(LatestText.text) == 0)
24.         {
25.             //Green
26.             LatestText.color = new Color32(76, 212, 105, 255);
27.         }
28.        
29.     }
30.  
31. }
32.  

 

oh! just seen your edit - will try it out

 

In your code, the Checker() function runs before you load the text files. Try the following instead:

Code (CSharp):

1.         CurrentText.text = System.IO.File.ReadAllText(@"C:\CurrentVersion.txt");
2.         LatestText.text = System.IO.File.ReadAllText(@"C:\LatestVersion.txt");
3.         Checker();

Good luck!

 

that was the issue! thanks @DryerLint <3

 

Haha, no problem!

 

Equals returns boolean value, you don't need to compare it with 0, it can be just

Code (CSharp):

1.         if (CurrentText.text.Equals(LatestText.text))
2.
