主题：大神看过来，帮我优化下这段代码

加入一个辅助列【是否处理完成】。

加入，你重置一个四级的人，那么上级（三级、二级、一级），也是应该得到值的了吧？不需要重复find查找一次。

重置列之前，全部行设置成false，处理完成的行设置成true，当遇到【处理完成=true】的时候，不要再往上查找，直接使用其路径。

优化

If e.DataCol.Name = "B001HYZLB_TuiJianRen" AndAlso e.DataRow("已经完成") = False Then
    Dim pdr As DataRow = e.DataTable.Find("B001HYZLB_YongHuID = '" & e.DataRow("B001HYZLB_TuiJianRen") & "'")
    Dim dic As new Dictionary(of DataRow, String)
    dic.add(e.DataRow, "")
    Do While pdr IsNot Nothing
        If pdr("已经完成") = True Then
            For Each key As DataRow In dic.Keys
                dic(key)  = pdr("B001HYZLB_CengJiMa") & dic(key)
            Next
        Else
            For Each key As DataRow In dic.Keys
                dic(key)  = "/" & pdr("B001HYZLB_YongHuID") & dic(key)
            Next
            dic.add(pdr, "")
            pdr = e.DataTable.Find("B001HYZLB_YongHuID = '" & pdr("B001HYZLB_TuiJianRen") & "'")
           
        End If
    Loop
    For Each key As DataRow In dic.Keys
        key("B001HYZLB_CengJiMa") =  dic(key) & "/" & key("B001HYZLB_YongHuID") & "/"
        key("已经完成") = True
    Next
End If

具体细节自己调试，如果还是无法处理。请上传具体实例测试。

参考代码

If e.DataCol.Name = "B001HYZLB_TuiJianRen" AndAlso e.DataRow("已经完成") = False Then
    Dim pdr As DataRow = e.DataTable.Find("B001HYZLB_Y")
    Dim dic As new Dictionary(of DataRow, String)
    Dim nls As new List(Of String)
    nls.add(e.DataRow("_Identify"))
    dic.add(e.DataRow, "")
    Do While pdr IsNot Nothing AndAlso nls.contains(pdr("_Identify")) = False
        application.Doevents
        output.show(dic.count & " " & pdr("_Identify"))
        If pdr("已经完成") = True Then
            Dim ls As new List(Of DataRow)
            ls.addRange(dic.keys)
            For Each key As DataRow In ls
                dic(key)  = pdr("B001HYZLB_CengJiMa") & dic(key)
            Next
            Exit Do
        Else
            Dim ls As new List(Of DataRow)
            ls.addRange(dic.keys)
            For Each key As DataRow In ls
                dic(key)  = "/" & pdr("B001HYZLB_YongHuID") & dic(key)
            Next

            nls.add(pdr("_Identify"))
            pdr = e.DataTable.Find("B001HYZLB_Y")
