How can one bind HashTable keys to a ListBox in VB.NET?

I'm helping a friend port some code that I have written in 开发者_JS百科Java to Visual Basic.NET. VB.NET is not my language of choose, so I am entirely new to it's quirks. How can I display keys from a HashTable in a ListBox?

Thanks in advance,

Sean W.

   For Each key As Object In myHashTable.Keys
       ListBox1.Items.Add(key.ToString)
   Next

or

   Dim enumerator As IDictionaryEnumerator = myHashTable.GetEnumerator()
   While enumerator.MoveNext
       ListBox1.Items.Add(enumerator.Key)
   End While

But you should use generic dictionaries instead that are type safe and therefore faster and less errorphrone.

    Dim myDictionary As New Dictionary(Of Int32, String)
    For i As Int32 = 1 To 1000
        myDictionary.Add(i, i & ". Entry")
    Next
    For Each key As String In myDictionary.Keys
        ListBox1.Add(key)
    Next

The Keys property on your Hashtable should be bindable directly to the Datasource property on your Listbox
