C#调用WPS将文档转换成pdf进行预览

最近在做预览功能有些压抑

vs启动项目可以生成wps实例

本地iis部署的站点却不行

原因是vs是管理员权限，而iis没有权限

解决方法

启动IIS，应用程序池-“选定的应用程序池”-高级设置-进程模型-标识：设置为管理员账号administrator

代码

1.安装WPS 2016 专业版

2.方法一：在项目中引用etapi.dll,wpsapi.dll,wppapi.dll，在WPS的安装目录中，如C:\Program Files (x86)\Kingsoft\WPS Office\10.8.2.6666\office6

方法二:根据实际需要科添加下面的COM引用
