word转pdf(使用office)

1.安装office软件

2.在vs中写代码

注意需要引入

Microsoft.Office.Interop.Word插件

/// <summary>

/// 将word转换成pdf文件

/// </summary>

/// <param name="sourcePath">源文件的绝对位置</param>

/// <param name="targetPath">目标文件的绝对位置</param>

/// <returns>返回bool是否转换成功</returns>

 public bool WordToPDF(string sourcePath, string targetPath)
        {
            bool result = false;
            Microsoft.Office.Interop.Word.Application application = new Microsoft.Office.Interop.Word.Application();
            Document document = null;
            try
            {
                application.Visible = false;
                document = application.Documents.Open(sourcePath);
                document.ExportAsFixedFormat(targetPath, WdExportFormat.wdExportFormatPDF);
                result = true;
            }
            catch (Exception e)
            {
                Console.WriteLine(e.Message);
                result = false;
            }
            finally
            {
                document.Close();
            }
            return result;
        }

　3.方法的调用

 #region 文件预览如果是pdf直接预览，如果是word进行转换之后预览
        /// <summary>
        /// 文件预览，如果是pdf直接预览，如果是word进行转换之后预览
        /// </summary>
        /// <param name="type">pdf还是word</param>
        /// <param name="url">文件地址</param>
        /// <returns></returns>
        public ActionResult PdfShow(string type, string url)
        {
            if (type == "word")
            {
                //绝对的资源位置到D://.../wwwroot/
                string webRootPath = _hostingEnvironment.WebRootPath;
                url = webRootPath +url;
                string target = webRootPath + "/files/wordToPdf/reportTest.pdf";
               //判断是否转换成功
                bool isSuccess = WordToPDF(url, target);
                if (isSuccess)
                {
                    //转换之后把文件的相对位置传给页面
                    ViewBag.files = "/files/wordToPdf/reportTest.pdf";
                }
            }
            else
            {
                ViewBag.files = url;
            }
            return View();
        }
        #endregion

　　最终实现，对word文件的转换和pdf的预览
