You can use <code>HttpUtility</code> class in <code>.net core</code> for decoding or encoding.

hope it will work.

I need to decode HTML characters in .NET Core (MVC6). It looks like .NET Core doesn't have WebUtility.HtmlDecode function which everybody used for that purpose before. Is there a replacement exist in .NET Core?

WebUtility.HtmlDecode replacement in .NET Core

我需要解码.NET核心(MVC6)中的字符。看起来.NET内核并没有以前每个人都使用过的WebUtility.HtmlDecode函数。.NET核心中是否存在替代方案？
