为什么更改Thread.CurrentThread.CurrentCulture会抛出一个日期而不是其他有效日期的错误

Question

如果我使用02/16/16，我会收到错误消息。但是，如果我使用02/07/16它可以正常工作。

Unhandled Exception: System.InvalidCastException: Conversion from string "02/16/

Module Module1
    Sub Main()
        Dim DateString As String = "02/07/16"
        Dim TestDate As DateTime = DateString
        Console.WriteLine(TestDate.ToLongDateString)
        Thread.CurrentThread.CurrentCulture = New CultureInfo("en-GB")
        TestDate = DateString
