利用鼠标点击次数来实现简单投票系统代码请教！
界面大概如下：
主要功能：
点击图中的红或蓝队中的按钮，分别从0开始递增（+1）。
结果分别显示在对应的按钮上面。
点击重置后，所有按钮显示结果清为0。

各位有空的话，请帮忙直接下载源代码编辑，方便指导！谢谢。

这个很容易啊，，，buttonClick事件中写代码private void button_Click(object sender, EventArgs e){ Button btn = (Button)sender; btn.Text = Convert.ToInt32(btn.Text.ToString()) + 1+""; MessageBox.Show("投票成功\r\n谢谢参与！");}如果要更新到数据，用button的tag属性存储相关的信息，再更新到数据库

下面代码替换 Vote.cs 的内容，然后启动 Vote 界面，看看效果吧
using System;using System.Windows.Forms;namespace WindowsFormsApplication1{ public partial class Vote : Form { private int[][] array = new int[][] { new int[6], new int[6] }; public Vote() { InitializeComponent(); this.btn1.Tag = "00"; this.btn2.Tag = "01"; this.button3.Tag = "02"; this.button4.Tag = "03"; this.button5.Tag = "04"; this.button6.Tag = "05"; this.button7.Tag = "10"; this.button8.Tag = "11"; this.button9.Tag = "12"; this.button10.Tag = "13"; this.button11.Tag = "14"; this.button12.Tag = "15"; this.Register(this.groupBox1.Controls); this.Register(this.groupBox2.Controls); } private void Register(Control.ControlCollection collection) { foreach (Control item in collection) { if (item is Button && item.Tag != null) { item.Click += this.ButtonClick; item.DoubleClick += this.ButtonClick; } } } private void Vote_Load(object sender, EventArgs e) { } private void ButtonClick(object sender, EventArgs e) { Button btn = (Button)sender; char[] arr = ((string)btn.Tag).ToCharArray(); btn.Text = (++this.array[arr[0] - '0'][arr[1] - '0']).ToString(); } }}

重置事件
将2个groupbox放在一个panel中
private void button_Click(object sender, EventArgs e)
{
foreach (Control item in this.panel1.Controls)
{
if (item is Button)
item.Text = "0";
}
}

相关判断自己写，，，int red=convert.toInt32(label20.text);int bule=convert.toInt32(label21.text);label22.text=red+bule+"";private void button_Click(object sender, EventArgs e){ Button btn = (Button)sender; btn.Text = Convert.ToInt32(btn.Text.ToString()) + 1+""; if(item.Tag.IndexOf("红")>-1) { red++; }else{bule++;}label20.text=red+"";label21.text=bule+"";label22.text=red+bule+""; MessageBox.Show("投票成功\r\n谢谢参与！");}
