Csharp 用C#从Word文档中删除重复的节控件和文本内容控件

发布于02月12日

带有重复节内容控件和文本内容控件的Word文档会动态填充内容.创建文档后，需要删除所有控件以使文档更易于编辑(应保留内容). 我已经为代码创建了一个基本框架，如何才能扩展到只删除控件而保留内容？

using DocumentFormat.OpenXml.Packaging;
using DocumentFormat.OpenXml.Wordprocessing;

using (WordprocessingDocument doc = WordprocessingDocument.Open(@"C:\Temp\Test\Weekly Marketing Dashboard.docx", true))
{

    MainDocumentPart mainPart = doc.MainDocumentPart;

    var sdtElements = mainPart.Document.Descendants<SdtElement>().ToList();

    foreach (var sdtElement in sdtElements)
    {
        sdtElement.Remove();
    }

    mainPart.Document.Save();
}

推荐答案

最后，我自己找到了一个解决方案，使用OpenXML:

    static void RemoveContentControls(OpenXmlElement element)
{
    // Replace SdtCells
    var sdtCells = element.Descendants<SdtCell>().ToList();
    foreach (var sdtCell in sdtCells)
    {
        // Clone and paste each child element
        foreach (OpenXmlElement child in sdtCell.SdtContentCell.ChildElements)
        {
            sdtCell.InsertBeforeSelf(child.CloneNode(true));
        }
        sdtCell.Remove();
    }

    // Replace SdtRuns
    var sdtRuns = element.Descendants<SdtRun>().ToList();
    foreach (var sdtRun in sdtRuns)
    {
        // Clone and paste each child element
        foreach (OpenXmlElement child in sdtRun.SdtContentRun.ChildElements)
        {
            sdtRun.InsertBeforeSelf(child.CloneNode(true));
        }
        sdtRun.Remove();
    }

    // Process childs recursive
    foreach (var child in element.ChildElements.ToArray()) // Use ToArray for save modification during iteration
    {
        RemoveContentControls(child);
    }
}
