[英]Editing & saving .docx in ASP.NET program using OpenXML & MemoryStream
[英]How to open docx file in ASP.NET MVC project using openxml for overwriting some text
我已经搜索了很多解决方案,但找不到任何解决方案。
我的 MVC 项目文件夹中有一个 .docx 文件,我想打开它来覆盖一些文本,但我无法这样做。
在我的项目文件夹中,我有一个Template
文件夹,在这个文件夹中有一个我想要打开的genrated.docx
文件。 这是我的代码:
using (WordprocessingDocument doc = WordprocessingDocument.Open
(@"~/Template/genrated.docx",true))
{
var body = doc.MainDocumentPart.Document.Body;
var paras = body.Elements<Paragraph>();
foreach (var para in paras)
{
foreach (var run in para.Elements<Run>())
{
foreach (var text in run.Elements<Text>())
{
if (text.Text.Contains("to-replace"))
{
text.Text = text.Text.Replace("to-replace", "replace-with");
run.AppendChild(new Break());
}
}
}
}
}
请在这件事上给予我帮助...
您替换文本的简单方法仅适用于简单情况。 不幸的是,一旦您使用 Microsoft Word 编辑模板,您的“要替换”文本可能会在多次运行中拆分。 这意味着如果您仅在单个Text
实例中查找文本,则无法找到“要替换”的Text
。
下面的单元测试演示了通过创建一个包含两个段落的文档,一个段落有一个带有“要替换”文本的单个Text
实例,另一个是将相同的文本拆分为两个Run
和Text
实例。

using WordprocessingDocument wordDocument = WordprocessingDocument.Create(stream, type);
MainDocumentPart mainDocumentPart = wordDocument.AddMainDocumentPart();
mainDocumentPart.Document =

new Body(

new Text(ToReplace))),

foreach (Run run in para.Elements<Run>())
