yes why not if don't work just do a little change like this
and u have to use "using System.Text;"

C#

StringBuilder arrayvalues = new StringBuilder();
            try
            {
                foreach (object o in arr)
                {
                    arrayvalues = arrayvalues.Append(o.ToString());
                }
            }

Don't use ArrayList, use System.Windows.Collections.Generic.List, http://msdn.microsoft.com/en-us/library/6sh2ey19.aspx[^].

Non-generic classes were rendered obsolete in the .NET Framework v.2.0, when generics were introduced. They are still used in legacy code (and ware not formally marked with Obsolete attribute to avoid breaking of backward compatibility), but in new development they make no sense and bad because they require type cast.

Also, consider review of the code design to use StringBuilder in first place. The solutions using foreach are correct though.
