在f# / c#中从WebBrowser获取cookie

我的目标是从webBrowser控件检索cookie。我试着用引用来做，但是事件。Map不允许我返回值:

let getCookie(url:string) = 
    let form  = new Form(Text="Internet Navigator")
    form.AutoScaleDimensions <- new System.Drawing.SizeF(6.0F, 13.0F)
    form.AutoScaleMode <- System.Windows.Forms.AutoScaleMode.Font
    form.ClientSize <- new System.Drawing.Size(849, 593)
    form.ResumeLayout(false)
    form.PerformLayout()
    let wb = new WebBrowser()
    wb.Visible<-true
    wb.AutoSize<-true
    wb.Size <- new System.Drawing.Size(804, 800)
    form.Controls.Add(wb)
    form.Show()

    let cookie = ref ""
    wb.Navigate(url)
    wb.DocumentCompleted
    |> Event.map(fun _ -> cookie:= wb.Document.Cookie)
    !cookie

理想情况下，有一种方法从Event.map(或类似的东西)内返回cookie值?

UPDATED:从函数返回cookie值而不是使用回调

let getCookie(url:string) = 
        let form  = new Form(Text="Internet Navigator")
        form.AutoScaleDimensions <- new System.Drawing.SizeF(6.0F, 13.0F)
        form.AutoScaleMode <- System.Windows.Forms.AutoScaleMode.Font
        form.ClientSize <- new System.Drawing.Size(849, 593)
        form.ResumeLayout(false)
        form.PerformLayout()
        let wb = new WebBrowser()
        wb.Visible<-true
        wb.AutoSize<-true
        wb.Size <- new System.Drawing.Size(804, 800)
        form.Controls.Add(wb)
        wb.DocumentCompleted |> Event.add (fun _ -> form.Close())
        wb.Navigate(url)
        form.ShowDialog() |> ignore
        wb.Document.Cookie
[<STAThreadAttribute>]
do
    let cookie = getCookie "http://www.google.com"
    Console.Read() |> ignore
