先生,我在vs2005中开发了以下代码,现在我只是在我的新项目中使用此模块@ vs 2008 .. 但这个错误已被提升。我不能能解决这个问题...空引用异常未被用户代码处理
Private Sub DataAccess()
Dim errHandle As New ErrorHandler
Dim lobjCommon As New eCopsCommonFunctions
Try
AccessCodeDrplst.DataSource = CType(lobjCommon.gfuncGetAllEnrollmentSource(), DataSet)
AccessCodeDrplst.DataValueField = "DataAccessCode"
AccessCodeDrplst.DataTextField = "DataAccessDesc"
AccessCodeDrplst.DataBind()
'lstEnrollmentSourceCode.DataValueField = "EnrollmentSourceCode"
'lstEnrollmentSourceCode.DataTextField = "EnrollmentSourceDesc"
'lstEnrollmentSourceCode.DataBind()
'"Beneficiary Election" is pre selected as default value. By pals on Oct 24th 2007
'lstEnrollmentSourceCode.SelectedValue = "B"
'lstEnrollmentSourceCode.Items.Insert(0, New ListItem("Select", "0"))
Catch ex As Exception
errHandle.gProcHandleErrors(ex, Session("MemberID"), "SPStatus.aspx.vb, gprocFillSEPCode")
Throw ex
Finally
lobjCommon = Nothing
///here the error occurs as 'NullException was unhandle by the user code'
errHandle = Nothing
End Try
End Sub
什么是'ErrorHandler'? – 2010-02-19 01:45:47
再次检查您发布的Finally块中的代码是否与您的程序中的代码实际匹配。 – 2010-02-20 18:14:44
