以下是ArrDictionary类： Public Class ArrDictionary     Private objCollection As New Collection     Private objDic As New DictionaryEntry     Private strKey， strValue As String     Public i As Integer     Public Function Item(ByVal Index As Integer) As Object         Try             Item = objCollection.Item(Index)         Catch ex As Exception             Item = "错误，无此项！"         End Try     End Function     Public Function Item(ByVal Key As String) As Object         Try             Item = objCollection.Item(Key)         Catch ex As Exception             Item = "错误，无此项！"         End Try     End Function     Public Sub Add(ByVal Key As String， ByVal Value As String)         objDic.Key = Key         objDic.Value = Value         objCollection.Add(objDic， objDic.Key)         i += 1     End Sub     Protected Overrides Sub Finalize()         MyBase.Finalize()         objCollection = Nothing         objDic = Nothing         strKey = ""         strValue = ""         i = 0     End Sub End Class

以下是调用代码段：                 Dim arrSQL As New ArrDictionary                 arrSQL.Add("收件号"， objExcelSheet.Cells(t， 1).Value)                 arrSQL.Add("房屋地址"， objExcelSheet.Cells(t， 2).Value)                 arrSQL.Add("建筑面积"， objExcelSheet.Cells(t， 3).Value)                 arrSQL.Add("房型"， objExcelSheet.Cells(t， 4).Value)                 arrSQL.Add("朝向"， objExcelSheet.Cells(t， 5).Value)                 arrSQL.Add("楼层"， objExcelSheet.Cells(t， 6).Value)                 arrSQL.Add("产别"， objExcelSheet.Cells(t， 7).Value)                 arrSQL.Add("金额"， objExcelSheet.Cells(t， 8).Value)                 arrSQL.Add("区域"， objExcelSheet.Cells(t， 9).Value)                 arrSQL.Add("竣工日期"， objExcelSheet.Cells(t， 10).Value)                 arrSQL.Add("使用年限"， objExcelSheet.Cells(t， 11).Value)                 arrSQL.Add("联系人"， objExcelSheet.Cells(t， 12).Value)                 arrSQL.Add("录入人"， objExcelSheet.Cells(t， 13).Value)                 arrSQL.Add("录入日期"， objExcelSheet.Cells(t， 14).Value)                 arrSQL.Add("所属分店"， objExcelSheet.Cells(t， 15).Value)                 ＇组合字段名                 Dim ColumnSQL As String                 ＇组合字段值                 Dim ValueSQL As String                 For i As Integer = 1 To arrSQL.i                     ColumnSQL += arrSQL.Item(i).Key.ToString & "，"                     ValueSQL += "＇" & arrSQL.Item(i).Value.ToString & "＇，"                 Next                 ＇组合SQL语句                 objCom.CommandText = "insert into content(" & ColumnSQL & ")" & _                 "values(" & ValueSQL & ")"                 ColumnSQL = ""                 ValueSQL = ""                 arrSQL = Nothing
