在MVC上的Microsoft站点上使用WordprocessingDocument后收到消息“MEMORY STREAM is not expANDABLE” [英] Got a message “ MEMORY STREAM IS NOT EXPANDABLE” after using WordprocessingDocument base on Microsoft site on MVC

问题描述

目前，我基于"搜索和替换文档部分中的文本（Open XML SDK）"。在Microsoft站点上。我已经意识到文件下载到我的驱动器后代码出了问题。

Currently, I was base on "Search and replace text in a document part (Open XML SDK)" on the Microsoft site. I've realized that the code got an issue after the file has downloaded to my drive.

所以我打开了那个文件并收到了一条消息

So I opened that file and got a message

< p style ="margin-bottom：0px; padding-right：0px; font-style：inherit; font-variant：inherit; font-weight：inherit; line-height：inherit; font-family：inherit; vertical-align：基线;明确：bo th">
内存流在sw.Write（docText）不可扩展;

MEMORY STREAM IS NOT EXPANDABLE at sw.Write(docText);

如何解决这个问题？

How to fix that?

在GenerateDocxHelper类中：

In GenerateDocxHelper class:

 private readonly MemoryStream _mem;
 private Dictionary<string, string> _dicData;

 public GenerateDocxHelper(string path)
 {
     _mem = new MemoryStream(System.IO.File.ReadAllBytes(path));
     _dicData = new Dictionary<string, string>();
 }

 public MemoryStream ReplaceTextInWord()
 {
     using (WordprocessingDocument wordDoc = WordprocessingDocument.Open(_mem, true))
        {


            string docText = null;
            using (StreamReader sr = new StreamReader(wordDoc.MainDocumentPart.GetStream()))
            {
                docText = sr.ReadToEnd();
            }


            foreach (var data in _dicData)
            {
                docText = docText.Replace(data.Key, data.Value);
            }

            using (StreamWriter sw = new StreamWriter(wordDoc.MainDocumentPart.GetStream(FileMode.Create)))
            {
                sw.Write(docText);
            }
        }

        _mem.Seek(0, SeekOrigin.Begin);





推荐答案

您应该创建MemoryStream容量值为0表示其可扩展。

You should create MemoryStream with capacity value as 0 which means its expandable.

例如

_mem = new MemoryStream(0);
