推荐答案

您只能检索和更新sdtContent的第一个Text. 要替换所有这些，简单的方法是:

You only retrieve and update the first Text of your sdtContent. To replace all of it, the simples way is:

• 删除所有文本
• 添加新文本

使用以下代码更新代码:

Update your code with:

if (alias != null)
{
    // delete all paragraph of the sdt
    sdt.Descendants<Paragraph>().ToList().ForEach(p => p.Remove());
    // insert your new text, who is composed of:
    // - A Paragraph
    // - A Run
    // - A Text
    sdt.Append(new Paragraph(new Run(new Text("As a consultant his job is to design, develop and love poney."))));
}

编辑:我忘记添加段落和运行

edit: I forget to add the paragraph and the run
