vb中的菜单条保存选项

Question

我做了一个菜单条，我需要知道如何制作我必须保存的选项实际保存。

这就是我所拥有的......虽然保存显然是错误的。

Private Sub SaveToolStripMenuItem_Click(sender As System.Object, e As System.EventArgs) Handles SaveToolStripMenuItem.Click 
    SaveToolStripMenuItem.DropDownItems("Save").Enabled = False

Private Sub SaveToolStripMenuItem_Click(sender As System.Object, e As System.EventArgs) Handles SaveToolStripMenuItem.Click
    Using writer As StreamWriter = New StreamWriter("book_list.txt", True)
        For Each line As String In ListBox1.Items
            writer.WriteLine(line)
        Next
    End Using
End Sub

假设您的ListBox被称为ListBox1
