You have several options:
(int) — Cast operator. Works if the object already is an integer at some level in the inheritance hierarchy or if there is an implicit conversion defined.
int.Parse()/int.TryParse() — For converting from a string of unknown format.
int.ParseExact()/int.TryParseExact() — For converting from a string in a specific format
Convert.ToInt32() — For converting an object of unknown type. It will use an explicit and implicit conversion or IConvertible implementation if any are defined.
as int? — Note the "?". The as operator is only for reference types, and so I used "?" to signify a Nullable<int>. The "as" operator works like Convert.To____(), but think TryParse() rather than Parse(): it returns null rather than throwing an exception if the conversion fails.
