如何在 C# 中写入 Json 文件？ [关闭]

Question

我正在使用 Unity 制作游戏。我试图制作一个选项菜单，但我的应用按钮不起作用。我想这样做，以便将选项写入 Json 文件。

我试过了，但我得到了这个错误：

Assets/Scripts/SettingsManager.cs(48,39): error CS0117: 'JsonUtility' does not contain a definition for 'toJson'

这是 C# 文件：

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;
using System.IO;

public class SettingsManager : MonoBehaviour
{
    public Toggle fullscreenToggle;
    public Dropdown resolutionDropdown;


    public Resolution[] resolutions;
    public GameSettings gameSettings;
    public Button applyButton;

    void OnEnable()
    {
        gameSettings = new GameSettings();

        fullscreenToggle.onValueChanged.AddListener(delegate { OnFullscreenToggle(); });
        resolutionDropdown.onValueChanged.AddListener(delegate { OnResolutionChange(); });
        applyButton.onClick.AddListener(delegate { OnApplyButtonClick(); });

        resolutions = Screen.resolutions;
        foreach (Resolution resolution in resolutions)
        {
            resolutionDropdown.options.Add(new Dropdown.OptionData(resolution.ToString()));
        }
    }

    public void OnFullscreenToggle()
    {
        gameSettings.fullScreen = Screen.fullScreen = fullscreenToggle.isOn;
    }

    public void OnResolutionChange()
    {
        Screen.SetResolution(resolutions[resolutionDropdown.value].width, resolutions[resolutionDropdown.value].height, Screen.fullScreen);
    }

    public void OnApplyButtonClick()
    {
        SaveSettings();
    }
    public void SaveSettings()
    {
        string jsonData = JsonUtility.toJson(gameSettings, true);
        File.WriteAllText(Application.persistentDataPath + "/gamesettings.json",jsonData);
    }

    public void LoadSettings()
    {

    }
}

你有一个错字。用大写T写ToJson

JsonUtility.ToJson
