c# - 在 OpenXML 中替换内容控件的文本

Question

我有一个 word 文件有很多Rich Text Content Control我想更改它的文本。我使用此代码。

 using (WordprocessingDocument theDoc = WordprocessingDocument.Open(docName, true))
 {
    MainDocumentPart mainPart = theDoc.MainDocumentPart;
    foreach (SdtElement sdt in mainPart.Document.Descendants<SdtElement>())
    {
        SdtAlias alias = sdt.Descendants<SdtAlias>().FirstOrDefault();
        if (alias != null)
        {
            string sdtTitle = alias.Val.Value;
            var t = sdt.Descendants<Text>().FirstOrDefault();
            t.Text="Atul works at Microsoft as a .NET consultant. As a consultant his job is to design, develop and deploy";
        }
    }
 }

它是用旧文本添加新文本。但是我想要replace这个！！！

Answer 1

您只需检索和更新 sdtContent 的第一个文本。要替换所有这些，最简单的方法是：

• 删除所有文本
• 添加新文本

更新您的代码：

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
