There are two direct problems here, and one indirect.
1) ArrayList is not the same as arrayList - C# is case sensitive.
2) You declare arr as a local variable - which means it is scoped to the method in which it is declared. You cannot access it via the class instance, which is what this is there for.

C#

ArrayList arr = new ArrayList(200);
arr.Add(obj);

The indirect problem is that ArrayList was superseded in V2 of C#, waaaay back in 2005 by Generic Collections, which are a lot better as they are typesafe. ArrayList should not be used in new projects.
