用ASP.NET编写一个计算器（能实现加减乘除的）

贴个最简单的吧:

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();
}
}
