C# - else steatment not triggering [on hold]

I have been creating a parser, in my parser I have the following function:

private object GetValue(Class Class, Method Method = null)
    {

        if (Token.IsOperator(Reader.Peek().Value))
        {
            string Peek = Reader.Peek().Value;
            Reader.Read();
            return new Operator() { Value = Peek };
        }
        else if (Method != null && Method.ConstainsLocal(Reader.Peek().Value))
        {
            string Peek = Reader.Peek().Value;
            Reader.Read();
            return Method.GetLocal(Peek);
        }
        else
        {
            string peek = Reader.Peek().Value;
            Reader.Read();
            return peek;
        }

        throw new Exception();

    }

It's calling the exception, not the else statement, why?
