Passing a constant array to a function in VB.NET

Question

I know that you can easily pass an array to a function, like the code below shows

Private Sub SomeFunction(ByVal PassedArray() As String)
    For i As Intege

No; there is no such thing as a constant array in CLI; arrays are always mutable. Perhaps a ReadOnlyCollection would be suitable?

In C# (so presumably similar in VB) you can do something like:

private readonly static ReadOnlyCollection fixedStrings
    = new ReadOnlyCollection(
        new string[] { "apple", "banana", "tomato", "orange" });

Which gives you a static (=shared) non-editable, re-usable collection. This works especially well if the method accepts IList, IEnumerable, etc (rather than an array, T[]).
