【C# OBD】标记中的文本换行

试试下面的代码：

DgnFile dgnFile = Session.Instance.GetActiveDgnFile();
            DgnModel dgnModel = Session.Instance.GetActiveDgnModel();
            TextBlockProperties txtBlockProp = new TextBlockProperties(dgnModel);
            txtBlockProp.IsViewIndependent = false;
            ParagraphProperties paraProp = new ParagraphProperties(dgnModel);
            DgnTextStyle txtStyle = DgnTextStyle.GetSettings(dgnFile);

            RunProperties runProp = new RunProperties(txtStyle, dgnModel);
            TextBlock txtBlock = new TextBlock(txtBlockProp, paraProp, runProp, dgnModel);
            txtBlock.AppendText("This is a textBlock Element");
            txtBlock.AppendLineBreak();
            txtBlock.AppendText("This is a  another line");
            TextHandlerBase txtHandlerBase = TextHandlerBase.CreateElement(null, txtBlock);
            DTransform3d trans = DTransform3d.Identity;
            trans.Translation = new DVector3d(6 * UorPerMas, 2 * UorPerMas, 3 * UorPerMas);  //UOR unit
            TransformInfo transInfo = new TransformInfo(trans);
            txtHandlerBase.ApplyTransform(transInfo);
            RgbColorDef rgbColorDef = dgnFile.GetColorMap().GetColor(5);
            int color = rgbColorDef.ToInt();
            ElementPropertiesSetter elePropSet = new ElementPropertiesSetter();
            elePropSet.SetColor(5);
            elePropSet.Apply(txtHandlerBase);
            txtHandlerBase.AddToModel();

TextElement是可以实现换行 但是我的这个是一个TagElement
