C# wps转pdf(word、ppt、excel),在线预览pdf

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
