尝试在VB.Net中获取日期时格式异常

Question

有人可以指导我为什么会收到此错误。我尝试了许多排列，但我无法解析字符串并从中获取日期

Public Function Starter(starterInput As LoginUserResponse) As List(Of GraphDataObj) Implements iSMS_Rest.Starter
Dim _currentUser = System.Web.HttpContext.Current.Cache(starterInput.tokenProp)
Dim res As Date
Dim provider As Globalization.CultureInfo = Globalization.CultureInfo.InvariantCulture
Dim dateString As String
dateString = starterInput.dateProp  // VALUE HERE: "2016-08-31T03:59:59.000Z"
res = Date.ParseExact(dateString, "dd/MM/yyyy", provider)
'SOME CODE
End Function

我得到的例外
