推荐答案

设置cookie ：

Set cookie:

Dim cookie As New HttpCookie("NameOfCookie")
cookie.Value = "ValueOfCookie"
Dim expiry As DateTime = DateTime.Now.AddYears(1)
cookie.Expires = expiry
Response.Cookies.Add(cookie)

读取cookie值：

Read cookie value:

Dim cookie As HttpCookie = Request.Cookies("NameOfCookie")
Dim strValue As String = cookie.Value.ToString()
