使用 C# 将 Word 文件（.docx 和 doc）转换为 .pdf 不起作用

我正在使用 Visualstudio 2010，我正在尝试将 word.docx 文件转换为 .pdf 文件，并且在本地工作正常，但在服务器上运行时显示错误为

Could not load file or assembly 'office, Version=14.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c' or one of its dependencies. The system cannot find the file specified.

我尝试过的是添加引用并放入 bin 文件夹中

Microsoft.Office.Interop.Word.dll
Microsoft.Office.Interop.Word.xml

如图

我的 .cs 代码如下

Microsoft.Office.Interop.Word.Application wordApp = new Microsoft.Office.Interop.Word.Application();

 wordApp.Visible = false;

            // file from
 object filename =Server.MapPath("word.docx"); // input

    // file to
 object newFileName = Server.MapPath("pdf/document_to_read_tomorrow.pdf"); // output
 object missing = System.Type.Missing;

            // open document
 Microsoft.Office.Interop.Word.Document doc = wordApp.Documents.Open(ref filename, ref missing, ref missing, ref missing, ref missing, ref missing,
                ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing,
                ref missing, ref missing, ref missing);

            // formt to save the file, this case PDF
 object formatoArquivo = Microsoft.Office.Interop.Word.WdSaveFormat.wdFormatPDF;

            // changes in paper size

 doc.PageSetup.PaperSize = Microsoft.Office.Interop.Word.WdPaperSize.wdPaperA4;

            // changes orietation paper
 doc.PageSetup.Orientation = Microsoft.Office.Interop.Word.WdOrientation.wdOrientPortrait;

            // other changes
 doc.PageSetup.LeftMargin = 20;
 doc.PageSetup.RightMargin = 0;


            // save file
 doc.SaveAs(ref newFileName, ref formatoArquivo, ref missing, ref missing, ref missing, ref missing, ref missing,
                ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing);

 doc.Close(ref missing, ref missing, ref missing);

 wordApp.Quit(ref missing, ref missing, ref missing);

我的 WebConfig 看起来像

由于内存泄漏和性能问题，不建议在服务器环境中使用 Office 互操作。您必须寻找一种托管解决方案来在服务器中将 PDF 转换为 Word，而不是在那里安装 Office 软件包和互操作程序集。有一些托管组件可以完成工作，但它们不是免费的。
