C#.NET逆波兰算法求解普通算式(支持自定义运算符)

用法举例： using System; using System.Collections.Generic; using RPN; namespace CSharp_Console { class Program { public static void Main(string[] args) { var rpn = new ReversePolishNotation(); rpn.AddOperation(new Power('^', "乘方", 5)); rpn.AddOperation(new E('e', "科学记数法", 5)); var expression = "3^6 +78*345+3-345/3e(-2)*(-9+3-5*7)"; try { Console.WriteLine(rpn.RpnExpression(expression)); Console.WriteLine(rpn.Calculate(expression)); } catch (Exception ex) { Console.WriteLine(ex.Message); } Console.ReadKey(); } }
