OpenXml sdk 损坏文件

Question

我正在使用 open xml sdk 来替换占位符，在 Whosebug 帖子的许多帮助下，我找到了如何替换我的占位符。更改这些占位符似乎可行，我可以检查更改后的 xml，但出于某种原因，无论如何文档似乎都已损坏。

我尝试了什么：

更改我的 docx zo ip 提取并手动替换一些文本并返回到 zip -> docx 也已损坏。

我的代码：

public void GenerateInvoice(TemplateViewModel viewModel)
        {
            //step, copy file -> read document return body -> change body -> save body -> convert to pdf
            
            
            //read document
            var wordReader = new DocumentReader();
            //var result = wordReader.Reader(@"D:/apps/DeigonAccountancy/DeigonAccountancy/Deigon.Frontend.Blazor/Files/invoiceTemplate.docx", @"D:/apps/DeigonAccountancy/DeigonAccountancy/Deigon.Frontend.Blazor/Files/" + (viewModel.Client.FirstName + "-" + viewModel.Client.LastName) + ".docx");
            
            if (!File.Exists(@"D:/apps/DeigonAccountancy/DeigonAccountancy/Deigon.Frontend.Blazor/Files/invoiceTemplate.docx"))
            {
                throw new FileNotFoundException("tbesta ni kloot");
            }

            File.Copy(@"D:/apps/DeigonAccountancy/DeigonAccountancy/Deigon.Frontend.Blazor/Files/invoiceTemplate.docx", @"D:/apps/DeigonAccountancy/DeigonAccountancy/Deigon.Frontend.Blazor/Files/" + (viewModel.Client.FirstName + "-" + viewModel.Client.LastName) + ".docx", false);

            var stream = File.Open(@"D:/apps/DeigonAccountancy/DeigonAccountancy/Deigon.Frontend.Blazor/Files/" + (viewModel.Client.FirstName + "-" + viewModel.Client.LastName) + ".docx", FileMode.Open);

            using (WordprocessingDocument wordDocument = WordprocessingDocument.Open(stream, true))

        }

简单的文本替换有效：差异检查：

有谁知道为什么最后我的文档损坏了？

使用 .net 5.0 和 blazor 前端

Answer 1

您永远不会关闭或处理 stream。

最简单的解决方案是使用 WordprocessingDocument.Open(<fileName>, ...) 重载并消除流。否则，给流它自己的 using() { } 块..
