[英]create word document with Open XML
我正在創建一個示例處理程序來生成簡單的Word文檔。
本文檔將包含文本Hello world
這是我使用的代碼(C#.NET 3.5),
我創建了Word文檔,但沒有文本,大小為0。
我該如何解決?
(我使用CopyStream方法,因為CopyTo僅在.NET 4.0及更高版本中可用。)
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);
}
}
}
通過將流代碼放在外部USING塊中,這對我有用。
這會導致調用WordprocessingDocument.Close
(通過Dispose方法)。
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();
}
}
我修改了你的代碼以使它工作。 保存下載后我可以正確打開它。 請參閱下面的修改。 希望這有幫助。
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();
}
}
string Filepath = @"C:\Users\infinity\Desktop\zoyeb.docx";
using (var wordprocessingDocument = WordprocessingDocument.Create(Filepath, DocumentFormat.OpenXml.WordprocessingDocumentType.Document))
{
MainDocumentPart mainPart = wordprocessingDocument.AddMainDocumentPart();
mainPart.Document = new DocumentFormat.OpenXml.Wordprocessing.Document();
Body body = mainPart.Document.AppendChild(new Body());
DocumentFormat.OpenXml.Wordprocessing.Paragraph para = body.AppendChild(new DocumentFormat.OpenXml.Wordprocessing.Paragraph());
DocumentFormat.OpenXml.Wordprocessing.Run run = para.AppendChild(new DocumentFormat.OpenXml.Wordprocessing.Run());
run.AppendChild(new DocumentFormat.OpenXml.Wordprocessing.Text("siddiq"));
wordprocessingDocument.MainDocumentPart.Document.Save();
}
轉到nuget包管理器並首先將其安裝到您的項目中
Install-Package DocumentFormat.OpenXml -Version 2.8.1
