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:WINDOWSassemblyGAC_32Kingsoft.Office.Interop.Etapi3.0.0.0__15d99fb7f8fe5cb4Kingsoft.Office.Interop.Etapi.dll
com组件 Upgrade WPS Presentation 3.0 Object Library (Beta)，对应“PowerPoint”，C:WINDOWSassemblyGAC_32Kingsoft.Office.Interop.Wppapi3.0.0.0__15d99fb7f8fe5cb4Kingsoft.Office.Interop.Wppapi.dll
com组件Upgrade Kingsoft WPS 3.0 Object Library (Beta)，对应“Word”，C:WINDOWSassemblyGAC_32Kingsoft.Office.Interop.Wpsapi3.0.0.0__15d99fb7f8fe5cb4Kingsoft.Office.Interop.Wpsapi.dll
