[RESOLVED] Problem adding ToolStripMenuItem array to MenuStrip

[gavio]

I have this code:

Dim oLanguages As SortedList = Languages() 'Languages() is my custom Function
Dim oLanguageMenu(oLanguages.Count) As ToolStripMenuItem

For n As Integer = 0 To oLanguages.Count - 1
    oLanguageMenu(n) = New ToolStripMenuItem(oLanguages.GetByIndex(n).ToString())
    oLanguageMenu(n).Tag = oLanguages.GetKey(n).ToString()
Next

Me.mnuViewLanguage.DropDownItems.AddRange(oLanguageMenu)

The last line produces an error: "value cannot be null. Parameter name: value". What am I doing wrong?
