Cookies collection bug? 1

[chpicker]

Can anyone explain to me why this code does not work in VB.NET?

[COLOR=blue]For Each[/color] myCookie [COLOR=blue]As[/color blue] HttpCookie [COLOR=blue]In[/color] HttpContext.Current.Request.Cookies

This line gives a Server Error: Unable to cast object of type 'System.String' to type 'System.Web.HttpCookie'.

If I change it to "As String" the line works.

Why is Request.Cookies a collection of strings and not a collection of cookies? IntelliSense tells me it's a collection of cookies, but it's not.

How can I do a simple iteration through the cookies for name/value pairs?

Try this:

Imports System.Net
        Dim response As HttpWebResponse = CType(request.GetResponse(), HttpWebResponse)
        For Each myCookie As Cookie In  response.Cookies

IntelliSense tells me it's a collection of cookies

Actually, it doesn't. It tells you that it returns a HttpCookieCollection which as you've found out is a collection of Strings. This can be proved by running this:

        Dim iEnum As IEnumerator = Request.Cookies.GetEnumerator()
        While iEnum.MoveNext
            Response.Write(iEnum.Current.GetType.ToString)
        End While

So, taking your previous example, you can just use the String to get the relevant cookie from the Cookies collection e.g.

        Dim c As HttpCookie
        For Each myCookie As String In HttpContext.Current.Request.Cookies
            c = Request.Cookies.Item(myCookie)
            ...
        Next

So, the strings in the collection are the NAMES of the cookies? That should get me what I need. Thanks!

Yes, that's correct as far as I can tell.
