如何将文档实例转换为文件流

Question

在过去的一个小时里我一直在努力解决这个问题。

有人可以帮助我将 Microsoft.Office.Interop.Word.Document 的实例转换为 FileStream 吗？我下面有这个功能，它不起作用，但可能会帮助你们了解我想要做什么：

 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;
         }
     }
 }

像这样的事情应该有效：

 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);

         }
 }

并且您将来必须删除临时文件。

您必须将文档保存到文件系统，然后将其读入 MemoryStream。我不认为序列化是这里的一个选项，因为 Document 类可能不是可序列化的。
