推荐答案

不确定您需要解决的问题究竟是什么，但此代码应计算项目数在您上面发布的集合中：

Not sure what exactly the problem is that you need to get solved but this code should count the items in the collection that you posted above:

Dim Count As Integer = 0
For Each item As Object In HttpContext.Current.Session("idTicket")
    Count = Count + 1
Next
Debug.WriteLine(Count)

For Each ... Next Statement（Visual Basic）| Microsoft Docs [ ^ ]
