我希望有人可以解决这个问题。我正在使用OpenXMl使用Open XML在Word文档的页眉，正文和页脚中搜索和替换文本。文本工作正常。但是图像并没有像我期望的那样被替换。图像（@“ C：\ temp \ pic \ Logo.gif”）在源中确实存在。但是永远不会正确显示在Word文档中。您可以在下面的区域中看到（#region“修改标题徽标”）有人可以协助吗？谢谢！

[首先，这是我手动插入Word文档中的图像（Picture.png）的标记。手动插入相同图像时，是否将代码创建的标记与Microsoft Word创建的标记进行了比较？这通常有助于发现标记中的错误（尽管并非总是如此，因为存在多种“通往罗马的道路”，并且同一事物通常可以多种方式表示）。例如，您可以使用Open XML生产率工具比较两个文档，并查看标记的差异以及创建正确标记所需的代码。

第二，下面的代码没有多大意义，因为您不需要foreach循环。该循环接受w:t的所有w:hdr后代，但从不使用循环主体中的currentText。
foreach (var currentText in headerPart.RootElement.Descendants<DocumentFormat.OpenXml.Wordprocessing.Text>())
{
textPlaceHolder = headerPart.RootElement.Descendants<Text>()
.Where((x) => x.Text == searchText).First();
}
循环的主体就足够了。我只用FirstOrDefault并检查是否为null，除非您100％确定文本将出现在所有（！）标头中。
