帮忙解释一下这段代码吧！

[xndx]

Private operator As String
Private operators As Collection

operators.Add UCase(rs("OPEGRANT"), rs("OPENAME"))

Public Function createCoilAuthorized() As Boolean
createCoilAuthorized = False
On Error Resume Next
createCoilAuthorized = operators(operator) Like "*C*"
Err.clear
End Function
对collection 不熟悉，那位办忙解释一下。
