你如何在VB.NET的HTTPCookie中使用Ampersand？

Imports System.Web
Imports System.Net

Dim cookie As New HttpCookie("myCookie")
cookie.Value = HttpUtility.UrlEncode("A & B")

HttpContext.Current.Response.Cookies.Add(cookie)

Dim myCookie As HttpCookie = HttpContext.Current.Request.Cookies("myCookie")
Dim decodedValue As String = HttpUtility.UrlDecode(myCookie.Value)
