本文主要是采用C\#将word文件转为PDF。程序中添加引用**using Microsoft.Office.Interop.Word;** 具体源码如下所示：

using System;
    using System.Collections.Generic;
    using System.Linq;
    using System.Web;
    using System.IO;
    using Microsoft.Office.Interop.Word;
    
    namespace Test.Zjn.Utils
    {
        public class WordToPdfHelper : IDisposable
        {
            public static readonly log4net.ILog log =
               log4net.LogManager.GetLogger(System.Reflection.MethodBase.GetCurrentMethod().DeclaringType);
            dynamic wps;
    
            public WordToPdfHelper()
            {
                //创建wps实例，需提前安装wps
                Type type = Type.GetTypeFromProgID("KWps.Application");
                wps = Activator.CreateInstance(type);
            }
    
            /// <summary>
            /// Word转PDF
            /// </summary>
            /// <param name="wordPath">Wps文件路径</param>
            /// <param name="pdfPath">Pdf文件路径</param>
            /// <returns></returns>
            public void ToPdf(string wordPath, string pdfPath = null)
            {
                try
                {
                    if (wordPath == null)
                    {
                        throw new ArgumentNullException("wpsFilename");
                    }
                    if (pdfPath == null)
                    {
                        pdfPath = Path.ChangeExtension(wordPath, "pdf");
                    }
                    Console.WriteLine(string.Format(@"正在转换 [{0}] -> [{1}]", wordPath, pdfPath));
    
                    //用wps 打开word不显示界面
                    dynamic doc = wps.Documents.Open(wordPath, Visible: false);
                    //doc 转pdf 
                    doc.ExportAsFixedFormat(pdfPath, WdExportFormat.wdExportFormatPDF);
                    //设置隐藏菜单栏和工具栏
                    //wps.setViewerPreferences(PdfWriter.HideMenubar | PdfWriter.HideToolbar);
                    doc.Close();
                }
                catch (Exception ex)
                {
                    log.Error("ToPdf()", ex);
                }
            }
    
            public void Dispose()
            {
                if (wps != null) { wps.Quit(); }
            }
        }
    }

**注意：使用时如果将public void ToPdf()方法改为public static void ToPdf()时，代码`doc.ExportAsFixedFormat(pdfPath, WdExportFormat.wdExportFormatPDF);`处会报异常**。
