Question

我遇到了无法调试的问题。

我有一个表单，当我按下按钮时，它打开另一个这样的表格：

wfrmBkrShotefHitpalgutNechasim_Perut.Close()
wfrmBkrShotefHitpalgutNechasim_Perut.Text = pPageHeader
wfrmBkrShotefHitpalgutNechasim_Perut.kerenGUID = KodKeren
wfrmBkrShotefHitpalgutNechasim_Perut.TaarichNechonut = Taarich
wfrmBkrShotefHitpalgutNechasim_Perut.SugHitpalgut = MisHitpalgut
wfrmBkrShotefHitpalgutNechasim_Perut.KodKvutzatHitpalgut = cm.Current("Kod").ToString
wfrmBkrShotefHitpalgutNechasim_Perut.MdiParent = Me.MdiParent
wfrmBkrShotefHitpalgutNechasim_Perut.Show()

它正确完成新表单的所有加载，并在完成后完成，如果失败则执行显示。

我得到的消息Exception是：项目已添加。键入字典：'kod'键被添加：'kod'

我不知道它在说什么列表/字典，我查看了异常的详细信息，我看到了：

**System.ArgumentException =** {"Item has already been added. Key in dictionary: 'kod'  Key being added: 'kod'"}

**Data =** {System.Collections.ListDictionaryInternal} 

**Values =**  {System.Collections.ListDictionaryInternal.NodeKeyValueCollection}

**Keys =** {System.Collections.ListDictionaryInternal.NodeKeyValueCollection}

好人们别担心，

在新表单中我填充了一个网格，其中有两个同名的列：“kod”

这就是问题所在。

谢谢你。最好的问候！
