C# 获取UI文本元素的高度不正确

我有一些代码为文本元素设置自定义，然后自动调整高度，如下所示：

Title.SetTextContainerSize("autoH", 330);

public void SetTextContainerSize(string fit, float dimension = 0)
    {
        if (UIElement.GetComponent<ContentSizeFitter>() == null)
            UISizeFitterComponent = UIElement.AddComponent(typeof(ContentSizeFitter)) as ContentSizeFitter;

        if (fit == "autoWH")
        {
            UISizeFitterComponent.horizontalFit = ContentSizeFitter.FitMode.PreferredSize;
            UISizeFitterComponent.verticalFit = ContentSizeFitter.FitMode.PreferredSize;
            base.SetDimensions( RectOptions.sizeDelta);
        }
        else if (fit == "autoW")
        {
            UISizeFitterComponent.horizontalFit = ContentSizeFitter.FitMode.PreferredSize;
            base.SetDimensions( new Vector2(RectOptions.rect.width, dimension));
        }
        else if (fit == "autoH")
        { //here is a problem.. 
            UISizeFitterComponent.verticalFit = ContentSizeFitter.FitMode.PreferredSize;
            Canvas.ForceUpdateCanvases();
            Debug.Log(new Vector2(dimension, RectOptions.rect.height));
            base.SetDimensions( new Vector2(dimension, RectOptions.rect.height));
        }
    }

public void SetTextContainerSize(string fit, float dimension = 0)
    {
        if (UIElement.GetComponent<ContentSizeFitter>() == null)
            UISizeFitterComponent = UIElement.AddComponent(typeof(ContentSizeFitter)) as ContentSizeFitter;

        if (fit == "autoWH")
        {
            UISizeFitterComponent.horizontalFit = ContentSizeFitter.FitMode.PreferredSize;
            UISizeFitterComponent.verticalFit = ContentSizeFitter.FitMode.PreferredSize;
        }
        else if (fit == "autoW")
        {
            base.SetDimensions(new Vector2(dimension, dimension));
            UISizeFitterComponent.horizontalFit = ContentSizeFitter.FitMode.PreferredSize;
            UISizeFitterComponent.verticalFit = ContentSizeFitter.FitMode.Unconstrained;
            Canvas.ForceUpdateCanvases();
            base.SetDimensions( new Vector2(RectOptions.rect.width, dimension));
        }
        else if (fit == "autoH")
        {
            base.SetDimensions(new Vector2(dimension, dimension));
            UISizeFitterComponent.horizontalFit = ContentSizeFitter.FitMode.Unconstrained;
            UISizeFitterComponent.verticalFit = ContentSizeFitter.FitMode.PreferredSize;
            Canvas.ForceUpdateCanvases();
            base.SetDimensions( new Vector2(dimension, RectOptions.rect.height));
        }
    }

但是当我调用函数来更新文本时，我从

Debug.Log（）

中得到以下结果，它表示宽度为330，高度为2077。在这种情况下，宽度是正确的，但高度甚至不接近

请参见此处实际元素及其正确高度的屏幕截图。

编辑2我的unity版本是2018.1.3f1

更新图元的实际高度时，我做错了什么

如果有完全其他的方法，我也愿意完全重写当前函数（如果Nessery:）

如果有不清楚的地方，请告诉我，以便我能澄清

编辑3我决定添加使用函数的类的完整代码和调用相应函数的代码，可能是因为出现了导致错误的问题：

这是调用problametic函数的代码：

var Title = new EasyText(new Vector2(390, -20), Vector2.zero, Data.title, 30, _color: new Color(0,0,0,1));
Title.SetTextContainerSize("autoH", 330);
Main.MainCanvas.Add(Title);

var titleBottom = (Title.Dimensions.y);
Debug.Log(titleBottom);

这是由上述代码调用的类：
