Hi,
As I mentioned in my post, this a property, not a function, it was,

       public ArrayList CircuitNames
       {
           get { return m_circuitNames; }
           set { m_circuitNames = value; }
       }
And now I need to pass an index via the Property, to store the string.
And access it at some point also.

Thanks for the Help
Jeff

That is a little harsh; until he added the argument "(int location)" it was
a property, albeit one with the wrong type (should have been string not
ArrayList) - so the real answer is:

"C# doesn't support named indexers; and if it did, they would probably be
with square-bracket notation to distinguish from functions."

Also - a typed collection would be preferable. If you are using 1.1, then
StringCollection - otherwise (2.0) perhaps just List<string>.

A bigger problem is possibly that this use of Insert is going to make it
very hard to update an item - i.e.

foo[0] = "abc";
foo[0] = "def";
foo[0] = "ghi";

// contains 3 items, not 1

But taking the existing example (with a standard "this" (Item) indexer):

class Foo {
   StringCollection circuitNames = new StringCollection();
   public string this[int location]
   {
       get
       {
           return circuitNames[location];
       }
       set
       {
           circuitNames.Insert(location, value);
       }
   }
}

then Foo foo = new Foo();
foo[0] = "abc";
foo[1] = "def";

etc
