hi David
the code snippet
int var
{
get { return var; }
set { var = value; }
}
creates an infinite loop as properties are internally implemented as
methods. So when you instantiate the object,
Crash c = new Crash(10);
This chain of action is what I understand
new Crash(10) -> var = 10; -> set { var = 10; } -> get { return var; } ->
get { return var; } ->...
the error lies in the fact that your property var does not refer to an
underlying field. You can try
int Var;
int var
{
get { return Var; }
set { Var = value; }
}
regards
feelite
