Which UrlEncode or HtmlEncode in .Net should we use?

I find that many methods in .net can provide UrlEncode

such as:

• System.Net.WebUtility
  
  
• Uri.EscapeDataString
  
  or Uri.EscapeUriString
  
  
• System.Text.Encodings.Web.UrlEncoder
  
  

For HtmlEncode

:

• System.Net.WebUtility
  
  
• System.Text.Encodings.Web.HtmlEncoder
  
  

And my question is, which one is recommended?
