Form.Close should be the answer as going by Microsoft Form.Close disposes the form as well if the form Modeless .
One more advantage you get from this method is from the events that are associated with the form
You can prevent the closing of a form at run time by handling the Closing event and setting the
Private Sub Form1_FormClosing(ByVal sender As Object, ByVal e As System.Windows.Forms.FormClosingEventArgs) Handles Me.FormClosing
If MessageBox.Show("Form is closing", "Form Close", MessageBoxButtons.YesNo, MessageBoxIcon.Hand) = Windows.Forms.DialogResult.No Then
e.Cancel = True
End If
End Sub
The above prevents the form being closed
When the form is opened as Modal form (using Showdialog) you can dispose the form explicitly
