    Dim lbl As Label = sender

    For Each frm2 As Form2 In 'How can I find specified form2? 
        If frm2.Tag = searchtag Then
            TextBox1.Text = frm2.justvariable & lbl.Tag

如何在VB.net中找到指定的form2并获取表单克隆变量？

Answer 1

您可以在列表中添加form2，然后遍历该列表。 E.g。

Dim ALForm2 as new list (of Form2)
Dim form2clone As New Form2 
form2clone.Tag = selectedpicid 
form2clone.Show()
ALForm2.Add (form2clone)

然后你可以循环通过ALForm2
