"Cannot Conver from <string> to 'string' ??? List and Scripting Newbie...

So i'm trying to enable a couple boolean values depending on what is entered in the two text fields (WindowsEditionCheck and GPUMakeModelText). I want it to look at what is entered and look at the list I have and enable the booleans under the if statement however the error:

cannot convert from System.Collections.Generic.List<string> to 'string'

I have absolutely no idea what this means... the full code is below...

Code (CSharp):

1. using System.Collections.Generic;
2. using UnityEngine;
3. using UnityEngine.UI;
4.  
5. public class configCheck : MonoBehaviour
6. {
7.  
8.     public Text WindowsEditionCheck = null;
9.     public Text GPUMakeModelText = null;
10.     public bool WinEd_10_64 = false;
11.     public bool Nvidia_Current = false;
12.    
13.     public List<string> currentNvidiaGPU = new List<string>();
14.  
15.  
16.     // Start is called before the first frame update
17.     void Start()
18.     {
19.         currentNvidiaGPU.Add("NVIDIA GeForce RTX 2080 Ti");
20.         currentNvidiaGPU.Add("NVIDIA GeForce RTX 2080");
21.         currentNvidiaGPU.Add("NVIDIA GeForce RTX 2070");
22.         WindowsEditionCheck();
23.     }
24.  
25.     void WindowsEditionCheck()
26.     {
27.         if ((WindowsEditionText.text.Contains("Windows 10")) && (GPUMakeModelText.text.Contains(currentNvidiaGPU)))
28.         {
29.             WinEd_10_64 = true;
30.             Nvidia_Current = true;
31.         }
32.      
33.     }
34.  
35. }
36.  

 

so I've realised in the code above I've asked if the individual like contains the entire list... which is the wrong way around (Line 27) so I've flipped this....

Code (CSharp):

1. if ((WindowsEditionText.text.Contains("Windows 10")) && (currentNvidiaGPU.Contains(GPUMakeModelText.text)))

This seems to have rid of the initial error, however this doesn't seem to change the boolean values at all - any ideas?

 

The error means you're passing in a List instead of a string.
A List of strings is still a List, so if you want to compare the values in the list, you need to reference them directly.
You can use a loop to accomplish this:

Code (CSharp):

1. for(int i = 0; i < currentNvidiaGPU.Count; i++) {
2.    if ((WindowsEditionText.text.Contains("Windows 10")) && (GPUMakeModelText.text.Contains(currentNvidiaGPU[i]))) {
3.       //etc...
4.    }
5. }

Treat Lists exactly as how you would treat arrays, because they work in the same way, except their collection of items is dynamic.

 

Hey Vryken,

Thanks for responding - I noticed after posting that:

Code (CSharp):

1. (GPUMakeModelText.text.Contains(currentNvidiaGPU))

is checking if the input contains the whole list... which it obviously wouldn't. I flipped it around to...

Code (CSharp):

1. (currentNvidiaGPU.Contains(GPUMakeModelText.text))

and this has gotten rid of the initial error, however this is still not flipping the boolean values.... any ideas?

 

If your values aren't returning what you expect, you need to see what you're checking against. What the value of GPUMakeModelText.text is. Remember stuff like caps matter.

 

yeah the list is made up of the exact values that GPUMakeModelText.text which is pulling it's info from the

Code (CSharp):

1. SystemInfo.graphicsDeviceName;

in another script... so I'm really not sure

EDIT: I just entered my own value into the text ui and the list - and it worked... now I'm REALLY lost

 

The problem with comparing strings is you may be missing something without realizing it. Maybe a hidden character or an extra space.

One thing to check is the length of the string you are passing in. If it's pulled from somewhere, check the length and then count what you see when you debug the value of the string and see if they match.
