WPF中实现

计算类的封装

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace wpfone1
{
    
        interface operater1
        {

            int calculate(int a, int b);

        }

        class Add : operater1
        {
            public int calculate(int a, int b)
            {
                return a + b;

            }
        }

        class Sub : operater1
        {
            public int calculate(int a, int b)
            {
                return a - b;
            }
        }

        class Mul : operater1
        {
            public int calculate(int a, int b)
            {
                return a * b;
            }
        }

        class Div : operater1
        {

            public int calculate(int a, int b)
            {

                if (b == 0)
                {

                    throw new Exception("除数不能为零！");

                }

                else
                {

                    return a / b;

                }

            }

        }
    }

 用策咯模式实现

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace wpfone1
{
  public  class Clacuter
    {
        private operater1 oper1;

        public Clacuter(string aSS)
        {

            switch (aSS)
            {

                case "+":

                    oper1 = new Add();

                    break;

                case "-":

                    oper1 = new Sub();

                    break;

                case "*":

                    oper1 = new Mul();

                    break;

                case "/":

                    oper1 = new Div();

                    break;

            }

        }

        public int Calculation(int a, int b)
        {

            return oper1.calculate(a, b);

        }
    }
}

写入类以及清除题库的类

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.IO;

namespace wpfone1
{
    class Writes
    {
        public void inscribe(string a, string b)
        {

            StreamWriter aaa = new StreamWriter(a, true);
            aaa.WriteLine(b);
            aaa.Close();

        }
        public void cleanup(string c, string d, string e)
        {
            StreamWriter ddd = new StreamWriter(c);
            ddd.WriteLine(" ");
            ddd.Close();
            StreamWriter aaa = new StreamWriter(d);
            aaa.WriteLine("");
            aaa.Close();
            StreamWriter fff = new StreamWriter(e);
            fff.WriteLine("");
            fff.Close();
        }
    }
}

        private void button1_Click(object sender, RoutedEventArgs e)//写入题
        {
            Writes writ = new Writes();
            string fnm = @"one";
            string text1 = this.textBox1.Text;
            writ.inscribe(fnm, text1);
            string fnmm = @"tow";
            string text2 = this.textBox2.Text;
            writ.inscribe(fnmm, text2);
            string fnm1 = @"fuhao";
            string text3 = this.comboBox1.Text;
            writ.inscribe(fnm1, text3);
            textBox1.Clear();
            textBox2.Clear();
        }

        private void button2_Click(object sender, RoutedEventArgs e)

            Writes clean = new Writes();
            clean.cleanup(a, b, c);

 测试

总结；

在这里实现感觉跟在windowform中差不太多只有很少的一部分代码有点不一样，用法也有些少许不同！

总的感觉就是在窗体的设计中比较容易操作，感觉比在windowform中更容易些！
