C#實現office文檔轉換爲PDF格式

C#實現office文檔轉換爲PDF格式

 1.安裝組件OfficeSaveAsPDFandXPS

需要安裝office 2007 還有一個office2007的插件OfficeSaveAsPDFandXPS

這是一個微軟官方出的office插件。

 

 

2.安裝好之後，打開VS,以VS2013爲例

2.1添加以下組件的引用

「項目」--「引用」--「添加引用..」--在程序集中搜索"Microsoft"，找到如下3個dll

Microsoft.Office.Interop.Word

Microsoft.Office.Interop.PowerPoint

microsoft.office.interop.Excel

 

dll成功引入後，項目的引用裏面則會出現相應的dll控件名稱。

 

修改上圖中3個dll的屬性"嵌入互操作類型"爲False

 

引入dll：Microsoft.Office.Core

文件版本爲15.0.5031.1000

該dll的文件名稱爲OFFICE.DLL

 即可看到如下圖的dll已引入成功

 

 

2.2相應類文件頂部添加以下組件的引用

using Word = Microsoft.Office.Interop.Word;
using Excel = Microsoft.Office.Interop.Excel;
using PowerPoint = Microsoft.Office.Interop.PowerPoint;
using Microsoft.Office.Core;
using System;
using Microsoft.Office.Interop.Excel;
using Microsoft.Office.Interop.PowerPoint;
using Microsoft.Office.Interop.Word;

 

我們可以使用一個枚舉類型來決定生成文件的類型

Word.WdExportFormat wd = Microsoft.Office.Interop.Word.WdExportFormat.wdExportFormatPDF;

Excel.XlFixedFormatType excelType = Microsoft.Office.Interop.Excel.XlFixedFormatType.xlTypePDF;

PowerPoint.PpSaveAsFileType ppType = Microsoft.Office.Interop.PowerPoint.PpSaveAsFileType.ppSaveAsPDF;

 

2.3相應類文件中的轉換代碼

權限配置第一種方案：

在組件在服務器中添加權限

單擊 開始，單擊 運行， 然後鍵入 DCOMCNFG。選擇要自動運行的應用程序。應用程序名稱如下所示：

Microsoft Access 97 - Microsoft Access 數據庫
Microsoft Access 2000/2002 - Microsoft Access 應用程序
Microsoft Excel 97/2000/2002 - Microsoft Excel 應用程序
Microsoft Word 97 - Microsoft Word Basic
Microsoft Word 2000/2002 - Microsoft Word 文檔

單擊 屬性打開此應用程序的屬性對話框。

 

1）標示—運行此應用程序的用戶賬戶—下列用戶；然後輸入Administrator用戶組中的一個用戶。

注：更改服務器中組件服務所用到的用戶密碼時，須在組件中重新輸入新的密碼，才能正常生成Word。

2）安全—啓動和**權限，選擇「自定義」，添加IIS_WPG用戶的本地啓動、本地**權限；

3）安全—訪問權限，選擇「自定義」，添加IIS_WPG用戶的本地訪問權限；

 

 權限配置第二種方案：

對DCOM組件進行權限配置：

1、打開comexp.msc -32

2、Microsoft Excel Application、和Microsoft Word 97-2003 Document屬性裏面進行配置，如下：

　　標識：設爲「交互式用戶」

　　安全：啓動和**權限添加「NETWORK SERVICE」，勾選本地啓動和本地**，訪問權限添加類似

 

以上兩點設置完成後還有問題，繼續以下操作：

3、應用進程池標識轉換爲「LocalSystem」

4、在C:/Windows/System32/config/systemprofile和C:/Windows/SysWOW64/config/systemprofile目錄下創建名爲Desktop目錄

 

出現的問題：發佈到服務器上後，WORD轉換沒問題，EXCEL轉換PDF時轉換卡住，只能生成temp的臨時文件，以下操作解決問題：

5、在DCOM組件的Microsoft Excel Application、和Microsoft Word 97-2003 Document屬性安全中額外添加「IIS_IUSRS」用戶組，權限跟之前的「NETWORL SERVICE」一樣
