子窗体如何传值给父窗体

用window.showModalDialog打开一个子窗体，关闭子窗体之后，想传一个值给父窗体，应该怎么写？求助

Answer 1

在Form1中
Public Class Form1
Public array(0)
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
My.Forms.childform.ShowDialog()

End Sub
End Class

在childform中
Public Class childform
Private Sub childform_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

End Sub
Private Sub TextBox1_DoubleClick(ByVal sender As Object, ByVal e As System.EventArgs) Handles TextBox1.DoubleClick
My.Forms.Form1.array(0) = TextBox1.Text
Me.Hide()
End Sub
End Class
改成了双击TextBox1返回值
