  • 基于C#的Cs架构简单开发一花店的售卖系统3

    花店售卖系统主要是为了熟悉CS结构开发,和C#中一些方法的使用,并不设计实用,故逻辑并不严谨,了解用法即可。

    购买界面,就是接受主界面点击的内容之后展示出来,支持选择数量,并会自动计算金额

    设计如下:

    代码:

     1 using System;
     2 using System.Collections.Generic;
     3 using System.ComponentModel;
     4 using System.Data;
     5 using System.Drawing;
     6 using System.Linq;
     7 using System.Text;
     8 using System.Threading.Tasks;
     9 using System.Windows.Forms;
    10 
    11 namespace BS结构用户界面
    12 {
    13     public partial class buy : Form
    14     {
    15 
    16         Image tp;
    17         string h;
    18         string jia;
    19         public buy()
    20         {
    21             InitializeComponent();
    22         }
    23 
    24         public buy(Image picture,string hua,string jiage)//构造函数
    25         {
    26             InitializeComponent();
    27             tp = picture;
    28             h = hua;
    29             jia = jiage;
    30         }
    31 
    32         private void button1_Click(object sender, EventArgs e)
    33         {
    34             int temp = int.Parse(this.textBox1.Text);
    35             temp += 1;
    36             string a = temp.ToString();
    37             this.textBox1.Text = a;
    38         }
    39 
    40         private void button2_Click(object sender, EventArgs e)
    41         {
    42             int temp = int.Parse(this.textBox1.Text);
    43             if (temp  > 0)
    44             {
    45                 temp -= 1;
    46             }
    47             string a = temp.ToString();
    48             this.textBox1.Text = a;
    49         }
    50 
    51         private void buy_Load(object sender, EventArgs e)//传递主界面点击值
    52         {
    53             this.pictureBox1.BackgroundImage = tp;
    54             this.label2.Text = h;
    55             this.label3.Text = jia;
    56 
    57         }
    58 
    59         private void button3_Click(object sender, EventArgs e)//计算金额
    60         {
    61             string m = this.textBox1.Text;
    62             string hua = this.label2.Text;
    63             int s, sum,shu;
    64             s = int.Parse(this.label3.Text);
    65             shu = int.Parse(m);
    66             sum = shu * s;
    67             MessageBox.Show("您购买了"+shu+""+hua+"一共是"+sum+"");
    68         }
    69     }
    70 }

    运行结果:

    选择数量后:
