UGUI 裁剪Text组件多余文本

希望能将text文本框中超出显示范围的文字裁剪掉,超出的部分用...代替
核心代码

void SetTextWithEllipsis(Text text, string content)
    {
        TextGenerator textGenerator = new TextGenerator();
        TextGenerationSettings settings = text.GetGenerationSettings(text.rectTransform.rect.size);
        settings.fontSize = text.fontSize;
        settings.fontStyle = text.fontStyle;
        settings.textAnchor = text.alignment;
        textGenerator.Populate(content, settings);

        int characterCountVisible = textGenerator.characterCountVisible;
        if (characterCountVisible > 0 && content.Length > characterCountVisible)
        {
            content = content.Substring(0,characterCountVisible-1) + "...";
        }

        text.text = content;
    }
