将单个 doc 文件转换为 pdf

Question

我正在使用以下代码 如何以编程方式将 Word 文件转换为 PDF ? 将 doc 文件转换为 pdf。但代码提到从特定目录获取所有 .doc 文件，而我希望只包含我从应用程序中选择的文件，或者有时只包含单个文件。

请指导我

谢谢！

相同的代码，针对单个文件进行修改：

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

...

// Create a new Microsoft Word application object
Microsoft.Office.Interop.Word.Application word = new Microsoft.Office.Interop.Word.Application();

// C# doesn't have optional arguments so we'll need a dummy value
object oMissing = System.Reflection.Missing.Value;

// Get a Word file
FileInfo wordFile = new FileInfo("myDoc.doc");

word.Visible = false;
word.ScreenUpdating = false;

// Cast as Object for word Open method
Object filename = (Object)wordFile.FullName;

// Use the dummy value as a placeholder for optional arguments
Document doc = word.Documents.Open(ref filename, ref oMissing,
    ref oMissing, ref oMissing, ref oMissing, ref oMissing, ref oMissing,
    ref oMissing, ref oMissing, ref oMissing, ref oMissing, ref oMissing,
    ref oMissing, ref oMissing, ref oMissing, ref oMissing);
doc.Activate();

object outputFileName = wordFile.FullName.Replace(".doc", ".pdf");
object fileFormat = WdSaveFormat.wdFormatPDF;

// Save document into PDF Format
doc.SaveAs(ref outputFileName,
    ref fileFormat, ref oMissing, ref oMissing,
    ref oMissing, ref oMissing, ref oMissing, ref oMissing,
    ref oMissing, ref oMissing, ref oMissing, ref oMissing,
    ref oMissing, ref oMissing, ref oMissing, ref oMissing);

// Close the Word document, but leave the Word application open.
// doc has to be cast to type _Document so that it will find the
// correct Close method.                
object saveChanges = WdSaveOptions.wdDoNotSaveChanges;
((_Document)doc).Close(ref saveChanges, ref oMissing, ref oMissing);
doc = null;

// word has to be cast to type _Application so that it will find
// the correct Quit method.
((_Application)word).Quit(ref oMissing, ref oMissing, ref oMissing);
word = null;

Answer 2

该代码正在查找文件夹中的所有 .doc 文件并循环遍历它们。如果您只有文件夹中的一个文件，它只会转换该文件。

您可以更改这行代码：

FileInfo[] wordFiles = dirInfo.GetFiles("*.doc");

仅查找您的文件，例如

FileInfo[] wordFiles = dirInfo.GetFiles("myselectedfile.doc");
