问题描述

我正在浏览器中编辑Word文档.每次我按保存按钮，都会生成一个副本.如何避免在asp.net中出现此重复副本?

I am editing a word document in the browser itself. Every time I press the save button it will generate a duplicate copy. How can I avoid this duplicate copy in asp.net?

推荐答案

您正尝试在 ReadOnly 中打开您的Word文件>保存按钮上的模式单击
为什么会这样?

You are trying to open your word file in ReadOnly mode on save button click
why so ?

您可以轻松地 C#编辑Word 文件，而无需生成重复副本和 ASP.NET导出到Word 并带有C#/VB.NET Word 库.

该库不依赖于Microsoft Word，也不使用

Hi,

you can easily C# edit Word file without generating a duplicate copy and ASP.NET export to Word with this C# / VB.NET Word library.

This library doesn''t have any dependency on Microsoft Word and doesn''t use C# Word Automation which makes it ideal for ASP.NET server applications.

Here is a sample C# code:

// Use the component in free mode.
ComponentInfo.SetLicense("FREE-LIMITED-KEY");

// Create and save an input document. 
// You don't have to do this if you already have an input document.
// This code is only provided as a reference how input document should look like.
var document = new DocumentModel();
document.Sections.Add(new Section(document, new Paragraph(document)));
document.Save(Path.Combine(Request.PhysicalApplicationPath, "Document.docx"), SaveOptions.DocxDefault);
// Instead use:
// Load an input document from application's root directory.
// var document = DocumentModel.Load(Path.Combine(Request.PhysicalApplicationPath, "Document.docx"), LoadOptions.DocxDefault);

// Edit first Run in first Paragraph or add new Run if Paragraph doesn't contain Run as first child.
var paragraph = document.Sections[0].Blocks.Cast<paragraph>(0);
if (paragraph.Inlines.Count > 0 && paragraph.Inlines[0].ElementType == ElementType.Run)
	paragraph.Inlines.Cast<run>(0).Text = txtword.Text;
else
	paragraph.Inlines.Add(new Run(document, txtword.Text));

// Microsoft Packaging API cannot write directly to Response.OutputStream.
// Therefore we use temporary MemoryStream.
using (MemoryStream documentStream = new MemoryStream())
{
	document.Save(documentStream, SaveOptions.DocxDefault);

	// Stream file to browser.
	Response.Clear();
	Response.ContentType = "application/vnd.openxmlformats";
	Response.AddHeader("Content-Disposition", "attachment; filename=Document.docx");

	documentStream.WriteTo(Response.OutputStream);

	Response.End();
}
