addrange for hashset

I have a hashset and would like to add it to a combobox.

So this works
Dim strLeaderNameListString() As String
ComboBox1.Items.Clear()
        ComboBox1.Text = Nothing
        Me.ComboBox1.Items.AddRange(strLeaderNameListString)
        ComboBox1.Select()

Anything close to make this work?
Dim strLeaderNameListString As HashSet(Of String)
ComboBox1.Items.Clear()
        ComboBox1.Text = Nothing
        Me.ComboBox1.Items.AddRange(strLeaderNameListString)
        ComboBox1.Select()

Error      1      Value of type 'System.Collections.Generic.HashSet(Of String)' cannot be converted to '1-dimensional array of Object'.

Try changing this line in the code :

 Me.ComboBox1.Items.AddRange(strLeaderNameListString)

To This :

 Me.ComboBox1.Items.AddRange(strLeaderNameListString.ToArray())

Sorry my fault I gave you the wrong line to change. Change that line back and change the following line of code.

 Me.ComboBox1.Items.AddRange(strLeaderNameListString)

To this :

 Me.ComboBox1.Items.AddRange(strLeaderNameListString.ToArray())
