你好，代码如下，试试吧
using System;

using System.Collections.Generic;

using System.ComponentModel;

using System.Data;

using System.Drawing;

using System.Drawing.Printing;

using System.Windows.Forms;

using System.IO;

using System.Diagnostics;

using Word;

回答2：

word有函数 ExportAsFixedFormat
MSDN上说明

The ExportAsFixedFormat method is used to publish a workbook to either the PDF or XPS format.

选一个word文件转为PDF
public static string WordConvertTOPDF(string path, string saveFielPath)
{
string result = "false";
object file = path;// _fileFullPath;
object readOnly = true;
object isVisible = true;
object confirmConverisons = false;
object openAndRepair = false;
Microsoft.Office.Interop.Word.Application wordApp = new Microsoft.Office.Interop.Word.Application();
try
{
doc = wordApp.Documents.Open(ref file, ref confirmConverisons, ref readOnly,
ref _missing, ref _missing, ref _missing, ref _missing, ref _missing, ref _missing,
ref _missing, ref _missing, ref isVisible, ref openAndRepair, ref _missing, ref _missing, ref _missing);

}
catch (Exception ex)
{
result = ex.ToString();
}

if (doc.ActiveWindow.ActivePane.View.Type != WdViewType.wdPrintView)
{
if (doc.ActiveWindow.View.SplitSpecial == WdSpecialPane.wdPaneNone)
doc.ActiveWindow.ActivePane.View.Type = WdViewType.wdPrintView;
else
doc.ActiveWindow.View.Type = WdViewType.wdPrintView;
}
int FilePageCount = GetPageCount(doc);//得到总页数
try
{
if (!System.IO.File.Exists(saveFielPath))
doc.ExportAsFixedFormat(saveFielPath, WdExportFormat.wdExportFormatPDF, false, WdExportOptimizeFor.wdExportOptimizeForPrint, WdExportRange.wdExportFromTo,
1, FilePageCount, WdExportItem.wdExportDocumentContent, false, true, WdExportCreateBookmarks.wdExportCreateNoBookmarks, true, true, false, _missing);
result = string.Empty;
}
catch (Exception ex)
{
result = ex.ToString();
}
finally
{
if (doc != null)
{
doc.Close(ref _missing, ref _missing, ref _missing);
doc = null;
}
if (wordApp != null)
{
wordApp.Quit(ref _missing, ref _missing, ref _missing);
wordApp = null;
}
GC.Collect();
GC.WaitForPendingFinalizers();
GC.Collect();
GC.WaitForPendingFinalizers();
}
return result;
}
若是代码生成word之后转
doc.ExportAsFixedFormat(saveFielPath, WdExportFormat.wdExportFormatPDF,
false, WdExportOptimizeFor.wdExportOptimizeForPrint,
WdExportRange.wdExportFromTo,
1,
FilePageCount, WdExportItem.wdExportDocumentContent, false, true,
WdExportCreateBookmarks.wdExportCreateNoBookmarks, true, true, false,
_missing);
