c# - 当 streamwriter 语句使用 void 和 int 时，如何解决布尔错误？

Question

所以我有这个代码：

StreamWriter sw;
sw = new StreamWriter(Application.dataPath + "safedata.txt");
sw.WriteLine(MainMenuscreen.ToggleShadows(MainMenuscreen.tc)); // This line is givng me the error

这是显示的错误代码：

严重性代码 描述 项目文件行抑制状态 抑制状态错误 CS1503 参数 1：无法从 'void' 转换为 'bool' Assembly-CSharp C:\Users\Owner\Downloads\Project 3 (1)\Project 3\Assets\Scripts\ SaveData.cs 46 活动

我不明白为什么会弹出这个错误，因为 ToggleShadows 是 void 函数，而 tc 是一个 int 变量：

public static int tc;

public static void ToggleShadows(int newToggle)
{
    Light[] lights = GameObject.FindObjectsOfType<Light>();

    foreach (Light light in lights)
    {
        if (newToggle == 0)
            light.shadows = LightShadows.None;
        else if (newToggle == 1)
            light.shadows = LightShadows.Hard;
        else
            light.shadows = LightShadows.Soft;
    }
    return;
}

我不知道为什么会出现布尔值。我正在尝试将数据从我的 gameSetting 文件中获取到我的 savedata 文件中。到目前为止，这个函数和变量只是给我问题的语句。

这是两个完整的代码：
