public todictionary 方法中的字典
public dictionary in todictionary method
我正在尝试访问在其他过程中的 todictionary
方法中创建的字典。
这是我想要的,但我遇到了编译错误。
Public dctOPT As New Dictionary(Of Integer, Object)
Sub Get_RTD_OPT()
Dim lstOPT = From C In DATA.CHAINs, O In DATA.OPTIONs, U In DATA.UDLies
Where C.CONTRACT = O.CONTRACT And O.UDLY_SYM = U.UDLY_SYM
Select C.ID, C.P_C, C.STRIKE, C.CONTRACT,
O.OPT_EXCHANGE, O.OPT_EXPIRY, O.OPT_SEC_TYPE, O.SYM,
U.CURRENCY
dctOPT = lstOPT.ToDictionary(Function(Z) Z.ID)
end sub
这可以编译,但是我无法在其他程序中访问 dctOPT
。
dim dctOPT = lstOPT.ToDictionary(Function(Z) Z.ID)
我需要将 dctOPT
复制到另一个 public 词典中吗?还是有更简单的方法?请问有什么建议吗?
你需要这个:
Public dctOPT As New Dictionary(Of Integer, Object)
Sub Get_RTD_OPT()
Dim lstOPT =
From C In DATA.CHAINs, O In DATA.OPTIONs, U In DATA.UDLies
Where C.CONTRACT = O.CONTRACT And O.UDLY_SYM = U.UDLY_SYM
Select C.ID, C.P_C, C.STRIKE, C.CONTRACT,
O.OPT_EXCHANGE, O.OPT_EXPIRY, O.OPT_SEC_TYPE, O.SYM,
U.CURRENCY
dctOPT = lstOPT.ToDictionary(Function(Z) Z.ID, Function(Z) CType(Z, Object))
End Sub
如果没有 Function(Z) CType(Z, Object)
,正在创建的字典类型是 Dictionary(Of Integer, <anonymous>)
,不能直接分配给 Dictionary(Of Integer, Object)
。转换正确地生成了正确类型的字典。
