wps转pdf

　　注：我是在wps试用期专业版，windows10系统 vs2019 webform（.net framework4.5）测试。

　　前提：需要下载安装wps专业版、企业版。

　　项目中需要引用wps的com组件

　　　　com组件Upgrade WPS Spreadsheets 3.0 Object Library (Beta) ，对应“Excel”，C:\WINDOWS\assembly\GAC_32\Kingsoft.Office.Interop.Etapi\3.0.0.0__15d99fb7f8fe5cb4\Kingsoft.Office.Interop.Etapi.dll

　　　　com组件 Upgrade WPS Presentation 3.0 Object Library (Beta)，对应“PowerPoint”，C:\WINDOWS\assembly\GAC_32\Kingsoft.Office.Interop.Wppapi\3.0.0.0__15d99fb7f8fe5cb4\Kingsoft.Office.Interop.Wppapi.dll

　　　　com组件Upgrade Kingsoft WPS 3.0 Object Library (Beta)，对应“Word”，C:\WINDOWS\assembly\GAC_32\Kingsoft.Office.Interop.Wpsapi\3.0.0.0__15d99fb7f8fe5cb4\Kingsoft.Office.Interop.Wpsapi.dll
