最近在做預覽功能有些壓抑

vs啟動項目可以生成wps實例

本地iis部署的站點卻不行

原因是vs是管理員權限撤逢，而iis沒有權限

解決方法

啟動IIS，應用程序池-“選定的應用程序池”-高級設置-進程模型-標識：設置為管理員賬號administrator

代碼

1.安裝WPS 2016 專業(yè)版

2.方法一：在項目中引用etapi.dll,wpsapi.dll,wppapi.dll搀罢，在WPS的安裝目錄中，如C:\Program Files (x86)\Kingsoft\WPS Office\10.8.2.6666\office6

方法二:根據實際需要科添加下面的COM引用
