C#+Aspose转office文档为PDF

下载Aspose对应插件并添加引用

//文件名
string fileName; 
//文件类型
string fileType;   
//office文件路径,形如 E://test.docx
string allPath=HttpContext.Current.Server.MapPath("\File\")+fileName+"."+fileType;
 //保存路径,形如 E://test.pdf
string newPath=HttpContext.Current.Server.MapPath("\File\")+fileName+".pdf";

    doc.Save(newPath, Aspose.Words.SaveFormat.Pdf);
}
