C# word文档转换成PDF格式文档

最近用到一个功能word转pdf，有个方法不错，挺方便的，直接调用即可，记录下

    方法：ConvertWordToPdf(string sourcePath, string targetPath)

    sourcePath：word文件路径

     targetPath：生成pdf文件路径

注：两个路径都为绝对路径

获取绝对路径：Server.MapPath("../zfjl/wj.docx");

  public static bool ConvertWordToPdf(string sourcePath, string targetPath)
        {
            Microsoft.Office.Interop.Word.WdExportFormat exportFormat;
            exportFormat = Microsoft.Office.Interop.Word.WdExportFormat.wdExportFormatPDF;
            bool result;
            object paramMissing = Type.Missing;
            word.ApplicationClass wordApplication = new word.ApplicationClass();
            word.Document wordDocument = null;
            try
            {
                object paramSourceDocPath = sourcePath;
                string paramExportFilePath = targetPath;
