我正在尝试从我的 AuthCookie 中获取用户名以用于控制其他变量。cookie 在此处的索引中定义：

<HttpPost()> _
Public Function Index(model As users.LogOnModel) As ActionResult
    'call LogOnModel
    '--------------------------
    If ModelState.IsValid Then

        'check username and password
        If model.pwd = db.users.First(Function(t) t.NT_id = model.NT_id).pwd Then

            'create an authentication cookie
            FormsAuthentication.SetAuthCookie(model.NT_id, False) 'set to false to destroy cookie on browser close

            'redirect action if login is successful
            Return RedirectToAction("Construction", "Home")
        Else
            ModelState.AddModelError("", "Invalid Username or Password")
        End If
    End If
    Return View(model)
End Function

我正在尝试在此处将其声明为一个变量以用于控制其他变量：

' User variables
    '---------------------------
    Public Shared uNT_id = IF(HttpContext.Current.User.Identity.Name is nothing, System.Environment.UserName, Trycast(HttpContext.Current.User.Identity.Name, String))


    Public Shared uid = db_apps.app_users.First(Function(t) t.NT_id = uNT_id).app_user_id
    Public Shared ussn = db_apps.app_users.First(Function(t) t.NT_id = uNT_id).ssn
    Public Shared upwd = db_apps.app_users.First(Function(t) t.NT_id = uNT_id).pwd
    Public Shared uname_first = db_apps.app_users.First(Function(t) t.NT_id = uNT_id).name_first

    ' App variables
    '---------------------------
    Public Shared appcount = db_apps.app_users.Count(Function(t) t.NT_id = uNT_id)
    Public Shared Function appid_multiple() As String
        Dim appidQ = From v In db_apps.app_users
                     Where v.NT_id = uNT_id
                     Select v

        'Create a String representation
        Dim stringList As New System.Text.StringBuilder
        Dim counter As Integer = 0
        For Each v In appidQ
            stringList.Append(v.app_id.ToString())

            'Separator
            If Not counter = appidQ.Count - 1 Then
                stringList.Append(",")
            End If
            counter += 1
        Next
        Return stringList.ToString
    End Function
    Public Shared appid = db_apps.app_users.First(Function(t) t.NT_id = uNT_id).app_id

最终结果是 uNT_id 需要等于他们登录网站的用户名，或者他们登录计算机的用户名，例如我的应该是：

uNT_id = "z148658"

然后我会使用 uNT_id 来控制所有这些其他变量。

以下代码返回我要返回的字符串

Public Shared uNT_id = If(HttpContext.Current.User.Identity.IsAuthenticated, HttpContext.Current.User.Identity.Name, System.Environment.UserName)

但是，如果用户登录并终止了应该终止 cookie 的窗口，则 HttpContext.Current.User.Identity.Name 仍然等同于最后一个登录用户。如果新用户尝试登录，情况也是如此.
