主题：[求助]If e.DataCol.Name = "科目"这里的科目是怎么执行判断的？

Dim dr As DataRow = e.DataRow
Dim dt As DataTable =DataTables("学生成绩")
If e.DataCol.Name = "科目" And dr.IsNull("科目") = False Then
    dr("分布_60分以下") = dt.Compute("Count(姓名)", dr("科目") & " < 60")
    dr("分布_60分以上") = dt.Compute("Count(姓名)", dr("科目") & " >= 60 And " & dr("科目") & " < 70" )
    dr("分布_70分以上") = dt.Compute("Count(姓名)", dr("科目") & " >= 70 And " & dr("科目") & " < 80" )
    dr("分布_80分以上") = dt.Compute("Count(姓名)", dr("科目") & " >= 80 And " & dr("科目") & " < 90" )
    dr("分布_90分以上") = dt.Compute("Count(姓名)", dr("科目") & " >= 90 And " & dr("科目") & " < 100" )
    dr("分布_100分以上") = dt.Compute("Count(姓名)", dr("科目") & " >= 100 And " & dr("科目") & " < 110" )
    dr("分布_110分以上") = dt.Compute("Count(姓名)", dr("科目") & " >= 110 And " & dr("科目") & " < 120" )
    dr("分布_120分以上") = dt.Compute("Count(姓名)", dr("科目") & " >= 120 And " & dr("科目") & " < 130" )
    dr("分布_130分以上") = dt.Compute("Count(姓名)", dr("科目") & " >= 130" )
End If

If e.DataCol.Name = "科目" And dr.IsNull("科目") = False Then
不是应该写成：

If e.Datacol.Nsme = “[科目]” And dr.IsNull("科目") = False Then

If e.DataCol.Name = "科目" And dr.IsNull("科目") = False Then

    If dr("科目") = "语文" Then

    ElseIf dr("科目") = "数学" Then

    End If
