Create a Word document using Open XML

Question

I am creating a sample handler to create a simple Word document.
This document will contain the text Hello world.

This is the code I'm using (C # .NET 3.5),
I created a Word document, but there is no text in it, the size is 0.
How can i fix this?
(I use the CopyStream method because CopyTo is only available in .NET 4.0 and higher.)

public class HandlerCreateDocx : IHttpHandler { public void ProcessRequest(HttpContext context) { using (MemoryStream mem = new MemoryStream()) { // Create Document using (WordprocessingDocument wordDocument = WordprocessingDocument.Create(mem, WordprocessingDocumentType.Document, true)) { // Add a main document part. MainDocumentPart mainPart = wordDocument.AddMainDocumentPart(); // Create the document structure and add some text. mainPart.Document = new Document(); Body body = mainPart.Document.AppendChild(new Body()); Paragraph para = body.AppendChild(new Paragraph()); Run run = para.AppendChild(new Run()); run.AppendChild(new Text("Hello world!")); mainPart.Document.Save(); // Stream it down to the browser context.Response.AppendHeader("Content-Disposition", "attachment;filename=HelloWorld.docx"); context.Response.ContentType = "application/vnd.ms-word.document"; CopyStream(mem, context.Response.OutputStream); context.Response.End(); } } } // Only useful before .NET 4 public void CopyStream(Stream input, Stream output) { byte[] buffer = new byte[16 * 1024]; // Fairly arbitrary size int bytesRead; while ((bytesRead = input.Read(buffer, 0, buffer.Length)) > 0) { output.Write(buffer, 0, bytesRead); } } }

This works for me by putting the streaming code into an external USING block.

This causes a call to WordprocessingDocument.Close (using the Dispose method).

 public void ProcessRequest(HttpContext context) { using (MemoryStream mem = new MemoryStream()) { // Create Document using (WordprocessingDocument wordDocument = WordprocessingDocument.Create(mem, WordprocessingDocumentType.Document, true)) { // Add a main document part. MainDocumentPart mainPart = wordDocument.AddMainDocumentPart(); // Create the document structure and add some text. mainPart.Document = new Document(); Body body = mainPart.Document.AppendChild(new Body()); Paragraph para = body.AppendChild(new Paragraph()); Run run = para.AppendChild(new Run()); run.AppendChild(new Text("Hello world!")); mainPart.Document.Save(); } context.Response.ContentType = "application/vnd.openxmlformats-officedocument.wordprocessingml.document"; context.Response.AppendHeader("Content-Disposition", "attachment;filename=HelloWorld.docx"); mem.Seek(0, SeekOrigin.Begin); mem.CopyTo(context.Response.OutputStream); context.Response.Flush(); context.Response.End(); } }

I modified your code to make it work. I can open it correctly after saving. Please check out my modified below. Hope this help.

 using (MemoryStream documentStream = new MemoryStream()) { using (WordprocessingDocument myDoc = WordprocessingDocument.Create(documentStream, WordprocessingDocumentType.Document, true)) { // Add a new main document part. MainDocumentPart mainPart = myDoc.AddMainDocumentPart(); //Create Document tree for simple document. mainPart.Document = new Document(); //Create Body (this element contains //other elements that we want to include Body body = new Body(); //Create paragraph Paragraph paragraph = new Paragraph(); Run run_paragraph = new Run(); // we want to put that text into the output document Text text_paragraph = new Text("Hello World!"); //Append elements appropriately. run_paragraph.Append(text_paragraph); paragraph.Append(run_paragraph); body.Append(paragraph); mainPart.Document.Append(body); // Save changes to the main document part. mainPart.Document.Save(); myDoc.Close(); context.Response.ClearContent(); context.Response.ClearHeaders(); context.Response.ContentEncoding = System.Text.Encoding.UTF8; SetContentType(context.Request, context.Response, "Simple.docx"); documentStream.Seek(0, SeekOrigin.Begin); documentStream.CopyTo(context.Response.OutputStream); context.Response.Flush(); context.Response.End(); } }
