        resolutions = Screen.resolutions;

        resolutionDropdown.ClearOptions();

        List<string> options = new List<string>();

        int currentResolution;
        
        for (int i = 0; i < resolutions.Length; i++)
        {
            string option = resolutions [i].width + " x " + resolutions[i].height;
            options.Add(option);

            if (resolutions[i].width == Screen.currentResolution.width &&
                resolutions[i].height == Screen.currentResolution.height)
            {
                currentResolutionIndex = i;
            }
        }
        resolutionDropdown.AddOptions(options);
        resolutionDropdown.value = currentResolutionIndex;
        resolutionDropdown.RefreshShownValue();
    }

    public void SetResolution (int resolutionIndex)
    {
        Resolution resolution = resolutions[resolutionIndex];
        Screen.SetResolution(resolution. width, resolution.height, Screen.fullScreen);
    }

    public void SetVolume (float volume)
    {
        audioMixer.SetFloat("Volume", volume);
    }

    public void SetQuality (int qualityIndex)
    {
        QualitySettings.SetQualityLevel(qualityIndex);

Compiler Error CS0103 is caused by using an undeclared variable or method. This issue happens where the currentResolutionIndex variable is never defined in the file.

void Start()
{
    /* Added the following line of code. To manage this condition when the condition is not always true, the variable must be initialized. */
    int currentResolutionIndex = -1;
    
    for (int i = 0; i < resolutions.Length; i++)
    {
        /* This condition may not always be true. */
        if (resolutions[i].width == Screen.currentResolution.width && resolutions[i].height == Screen.currentResolution.height)
        {
            currentResolutionIndex = i;
        }
    }
   
    /* If the condition never works correctly, you should control and manage this condition. */
    if(currentResolutionIndex != -1)
    {
        resolutionDropdown.value = currentResolutionIndex;
    }
    else
    {
        /* Exception Handling */
    }
}

Thank so much i will see if it works – Maxim Wagner Dec 21 '21 at 01:24
There's no reason why it shouldn't work! You can't use a variable without defining it because you're not coding in python. – Sercan Dec 21 '21 at 01:25
thanks for the help but, i am a beginner and i dont know how to control and manage the exeption – Maxim Wagner Dec 21 '21 at 01:28

If you are a new user then read [this article](https://stackoverflow.com/tour). You should also read [this post](https://stackoverflow.com/questions/881473/why-catch-and-rethrow-an-exception-in-c) to learn exception handling in C#. – Sercan Dec 21 '21 at 01:36
