如何将文档实例转换为FileStream

Question

I've Been struggling with this in the past hour.

Can someone help me to convert an instance of Microsoft.Office.Interop.Word.Document to FileStream? I have this function below which does not work but might help you guys to have an idea of what im trying to do:

 using System;
 using System.Collections.Generic;
 using System.Linq;
 using System.Runtime.Serialization;
 using System.ServiceModel;
 using System.Text;
 using Microsoft.Office.Interop.Word;
 using System.IO;

 namespace DropDownTemplate.Web.WebServices.Word
 {
     // NOTE: You can use the "Rename" command on the "Refactor" menu to change the class name "WordGenerator" in code, svc and config file together.
     public class WordGenerator : IDocumentGenerator
     {
         FileStream IDocumentGenerator.GenerateDocument()
         {
             // For optional parameters create a missing object
             object missing = System.Reflection.Missing.Value;
             // open the document specified in the fileName variable
             Document adoc = new Document();
             adoc.InlineShapes.AddPicture(@"http://localhost:2014/Resources/MG.PNG", ref missing, ref missing, ref missing);
             using (StreamReader y = new StreamReader())
             {
                 y.Read(adoc);   
             }
             return adoc;
         }
     }
 }

Answer 1

You muse save the document to the file system and then read that into a MemoryStream. I don't think serialization would be an option here because Document class is not Serializable probably.

Answer 2

Something like this should work:

 public class WordGenerator : IDocumentGenerator
 {
         FileStream IDocumentGenerator.GenerateDocument()
         {
                object missing = System.Reflection.Missing.Value;
                Document adoc = new Document();
                adoc.InlineShapes.AddPicture(@"http://localhost:2014/Resources/MG.PNG", ref missing, ref missing, ref missing);

                // save the doc file
                object fileName = Path.GetTempFileName();
                adoc.SaveAs(ref fileName, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing);

                // quit word and release COM objects
                object saveChanges = WdSaveOptions.wdDoNotSaveChanges;
                adoc.Application.Quit(ref saveChanges, ref missing, ref missing);
                Marshal.ReleaseComObject(adoc);

                // return the stream
                return new FileStream((string)fileName, FileMode.Open);

         }
 }

and you'll have to delete the temp file sometime in the future.
