我只是开了多个窗体，为什么出点这种警告啊，看着好不爽

警告 1 在“C:\Users\lenovo\AppData\Local\Temporary Projects\7.5.1\Form2.Designer.vb”中声明的 class“Form2”和分部 class“Form2”在 namespace“_1”中冲突，但由于其中的一个被声明为 Partial，因此正在合并。 C:\Users\lenovo\AppData\Local\Temporary Projects\7.5.1\Form1.vb 20 14 7.5.1
最前面代码是
Public Class Form1
Dim form2 As New Form2
Dim form3 As New Form3 Private Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click
form2.Show() End Sub Private Sub Button2_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button2.Click
form3.Show() End Sub Private Sub Button3_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button3.Click
Close() End Sub
End Class
Public Class Form2 Private Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click
Me.Hide() End Sub
End Class
Public Class Form3 Private Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click
Me.Hide() End Sub
End Class
