NetCore的word轉html很少見,特別是帶圖片轉換為html的
查了很多資料做了些嘗試
DocX 免費的不支持NetCore了
后來在nuget上查找發現DotNetCore.NPOI可以參考(后來發現NPOI其實就可以了)
然后就開始嘗試
獲取圖片有點坑 踩了好大一會 找了好久才找到對應關系 然后就是 兩張一樣的圖片只會顯示一張
github地址如下 如果有幫助 麻煩幫忙Star一下謝謝

首先nuget參考 NPOI
Install-Package NPOI
理論上如果不是netcore的話 直接參考NPOI就好
可能不太完善 可以稍微改進下
反正可以正常在centos上word轉成html了
FileStream stream = new FileStream("1.docx", FileMode.Open,FileAccess.Read);
更新了代碼,現在我專案中就是用的這個類,上傳阿里云部分自己改改
