用ASP.NET编写一个计算器（能实现加减乘除的）

Operation类:

class Operation

{

public static double GetResult(double numberA, double numberB, string operate)

{

double result = 0d;

switch (operate)

{

case "+":

result = numberA + numberB;

break;

case "-":

result = numberA - numberB;

break;

case "*":

result = numberA * numberB;

break;

case "/":

result = numberA / numberB;

break;

}

return result;

}

}

Program.cs:

class Program

{

static void Main(string[] args)

{

Console.WriteLine("请输入数字A：");

string strNumberA = Console.ReadLine();

Console.WriteLine("请输入运算符号(+ - * /)");

string strOperate = Console.ReadLine();

Console.WriteLine("请输入数字B：");

string strNumberB = Console.ReadLine();

string strResult;

strResult = Convert.ToString(Operation.GetResult(Convert.ToDouble(strNumberA), Convert.ToDouble(strNumberB), strOperate));

Console.WriteLine("结果是:" + strResult);

Console.ReadLine();

}

}
