100分求同学们解释一下一个方法,比较简单的,大家都来吧

Private Shared Function GetOrdinals(ByVal objProperties As ArrayList, ByVal dr As IDataReader) As Integer()
//我用的C#,搞不懂这么定义是什么意思?
Dim arrOrdinals(objProperties.Count) As Integer
Dim intProperty As Integer

If Not dr Is Nothing Then
For intProperty = 0 To objProperties.Count - 1
arrOrdinals(intProperty) = -1 //这句是干啥的?
Try
arrOrdinals(intProperty) = dr.GetOrdinal(CType(objProperties(intProperty), PropertyInfo).Name)
Catch
' property does not exist in datareader
End Try
Next intProperty
End If

Return arrOrdinals

End Function

//我用的C#,搞不懂这么定义是什么意思?
-------------------------------------------------------------------------------------
定义了一个静态方法GetOrdinals()

[ChengKing]

arrOrdinals(intProperty) = -1 //这句是干啥的?
answer: 这是给数组的每一个元素赋值:-1,即初始化

[fengliudai]

Dim arrOrdinals(objProperties.Count) As Integer

是这句没搞懂

好了,懂了,多谢了()这样的数组写法把偶搞蒙了
