C# web實現word 轉Html、office轉Html、pdf轉圖片 在線預覽文件

 改篇 pdf 預覽再本機沒問題，發布再iis中 不行 ，（使用剪貼板的問題..excel和word 可以,）

pdf解決：請看我的博文 ----最終解決篇

詳細配置及代碼

word 轉Html

 1 /// <summary> 
 2         /// word轉成html 
 3         /// </summary> 
 4         /// <param name="wordFileName"></param>

 6         {
 7             //在此處放置用戶代碼以初始化頁面 
 8             Word.ApplicationClass word = new Word.ApplicationClass();
 9             Type wordType = word.GetType();
10             Word.Documents docs = word.Documents;
11             //打開文件 
12             Type docsType = docs.GetType();
13             Word.Document doc = (Word.Document)docsType.InvokeMember("Open", System.Reflection.BindingFlags.InvokeMethod, null, docs, new Object[] { wordFileName, true, true });
14             //轉換格式，另存為 
15             string a = doc.Comments.ToString();
16             Type docType = doc.GetType();
17             string wordSaveFileName = wordFileName.ToString();
18 
19       
20 
21            string strSaveFileName = htmlWord + "\\" + Path.GetFileNameWithoutExtension(wordSaveFileName) + ".html";

pdf  轉圖片

說明：本方法 用  acrobat 的官方接口  

需要安裝  acrobat   professional  8.0或更高版本

然后再vs中添加com組件  abode  acrobat  版本號   type  library  只有安裝了上面軟件 才回有

 

在web頁 頭部 添加   AspCompat="true"    控制台程序 要在main函數上加  [STAThread]  保證單線程模型下 才能訪問 剪貼板

關於發布：

offic 組件發布問題

 我的服務器環境是 windows servers 2008 64位操作系統

 

1、  在服務器上安裝Office的Excel相關軟件（推薦安裝Office 2007）；

2、  Cmd中輸入命令 comexp.msc -32  啟動組件服務（啟動組件服務 方法  運行 mmc、mmc -32(32) 、DCOMCNFG.exe(64)） 不行一個一個

3、  依次雙擊"組件服務"->"計算機"->"我的電腦"->"DCOM配置"；

4、  在"DCOM配置"中找到"Microsoft Excel Application",在它上面點擊右鍵,然后點擊"屬性",彈出"Microsoft Excel應用程序屬性"對話框；

5、  點擊"標識"標簽,選擇 啟動用戶（默認選項） ；

6、  點擊"安全"標簽,在以下  三個項目中都選中   “自定義”  添加 ”everyone”  並分配最大權限（全選）

7、設置Web.config文件   在Web.config文件的<system.web>中加入<identity impersonate="true"/>  （沒有這一步 會報Excel進程無法打開相應的excel文件）。

Ok了

 

 

Word 配置同上。

 

關於pdf 發布：   需要在 服務器上安裝 上訴軟件

     我在本機vs 和服務器vs中 測試沒問題  ，發布到iis中  無法取到 剪貼板中的數據    也不報錯     iis中應用程序池 的權限我也設置到最大  ，依然無果。

還是這種 iis中訪問剪貼板的 方法 違反 安全性 或剪貼板只能在單線程模型下訪問  與這個相悖 ？？？？？？？？？？？？？？？？

歡迎留言探討》》》》》
