MyTask2
先把核心代码贴上
public void solve()
{
//Console.WriteLine("请输入你需要生成多少人的数据以及年龄最大值(75以内)：");
//int flag,end,maxAge;
int test=0;
//flag = int.Parse(Console.ReadLine());
//maxAge = int.Parse(Console.ReadLine());
Random rd = new Random(GetRandomSeed());
Random rdd = new Random(GetRandomSeed());
clearDataPie();//每次分析之前都要对之前一次的数据清空
//数据生成
for (int i = 0; i < numPerson; i++)
{
int age = rd.Next(1, agePerson+1);
int sex = rdd.Next(0, 2);
if(flagSex == 1)
{
sex = Nsex;
}
PersonHabit ph = new PersonHabit(age,sex);//这里随机构造出年龄和性别
//可自己选取性别，默认为空的话则随机
calculateDataPie(ph);//每个人的数据
solveSum(ph);//生活习惯数据统计
//messagePrint+="年龄:"+age+" 性别:"+((sex==0)?"男":"女")+"\r\n";
// Console.WriteLine("年龄:"+age+" 性别:"+((sex==0)?"男":"女"));
//ph.Userid = i + 1;
string sql =
"insert into LifeHabit()";
// if(==false){
// test = 1;
// }
if(this.radioButton1.Checked == true&&this.radioButton2.Checked == false)
{
sqlExcute(sql);
this.button4.Enabled = true;
}
//Console.WriteLine("正在生成数据中... 当前为第"+(i+1)+"个人");
//System.Threading.Thread.Sleep(2000);
if (i == numPerson)
break;
//ph.print();
}
countDataPie();//统计完所有数据之后进行饼状图绘制
if(test==1)

}这是最原始的框架，其实最开始做的时候只是一个dos界面，然后能插入数据和取出数据的程序
后面增加了WinForm界面，然后把一些基本的数据能够显示出来
这里给一些比较常用的方法吧
public static int GetRandomSeed()//随机数种子
{
byte[] bytes = new byte[4];
System.Security.Cryptography.RNGCryptoServiceProvider rng = new System.Security.Cryptography.RNGCryptoServiceProvider( );
rng.GetBytes(bytes);
return BitConverter.ToInt32( bytes , 0 );
}public static string returnPercent(int a)//返回数值的百分比
{
double percent=Convert.ToDouble(a)/Convert.ToDouble(numPerson);
string result=string.Format("{0:0.00%}",percent);//得到5.88%
return result;
}public bool outputExcel()//数据导出Excel模版
{
using (DbConnection connection = new SqlConnection("server=localhost; user id=sa; password=; database="))
{
connection.Open();
DbCommand command = connection.CreateCommand();
command.CommandType = System.Data.CommandType.Text;
command.CommandText = "";//sql表字段
var reader = command.ExecuteReader();
Excel.Application application = new Excel.Application();
Excel.Workbook workbook = application.Workbooks.Add();
Excel.Worksheet worksheet = workbook.ActiveSheet as Excel.Worksheet;
var index = 1;
while (reader.Read())
{
worksheet.Cells[index, 1] = reader.GetInt32(0).ToString();
worksheet.Cells[index, 2] = reader.GetString(1);
worksheet.Cells[index, 3] = reader.GetString(2);
if ("NULL".Equals(reader.GetString(3))==true)
worksheet.Cells[index, 4] = "";
worksheet.Cells[index, 4] = reader.GetString(3);
if ("NULL".Equals(reader.GetString(4)) == true)
worksheet.Cells[index, 5] = "";
worksheet.Cells[index, 5] = reader.GetString(4);
if (reader.GetString(5) == null)
worksheet.Cells[index, 6] = "";
worksheet.Cells[index, 6] = reader.GetString(5);
if (reader.GetString(6) == null)
worksheet.Cells[index, 7] = "";
worksheet.Cells[index, 7] = reader.GetString(6);
if (reader.GetString(7) == null)
worksheet.Cells[index, 8] = "";
worksheet.Cells[index, 8] = reader.GetString(7);
index++;
}
reader.Close();
workbook.SaveAs(@"F:\test.xls");
workbook.Close();
application.Quit();
connection.Close();
}
return true;
}void Timer1Tick(object sender, System.EventArgs e)//监控饼状图并且在form1内传入数据
//因为之前设置的是在design里面做，是可以弄出来的，然后鉴于数据不知道怎么传输过来，我就在design里面设置timer，然后可以做到
//点击按钮之后启动
{
if(flagAgeShowPie == 1)
{
chart1.Series["Series1"].Points.DataBindXY(xValues, yValues1);
//chart1.Series["Series1"].Label = "#PERCENT{P}";
//System.Diagnostics.Debug.WriteLine("123321"+yValues2[0]+" "+yValues3[1]+" "+yValues4[2]);
chart2.Series["Series2"].Points.DataBindXY(xValues, yValues2);
//chart2.Series["Series2"].Label = "#PERCENT{P}";
//chart2.Series["Series2"].LegendText = "偏低";
chart3.Series["Series3"].Points.DataBindXY(xValues, yValues3);
//chart3.Series["Series3"].Label = "#PERCENT{P}";
//chart3.Series["Series3"].LegendText = "中";
chart4.Series["Series4"].Points.DataBindXY(xValues, yValues4);
//chart4.Series["Series4"].Label = "#PERCENT{P}";
}
if(flagValueChartAreaComboBox<=10&&flagLifeHabitButton==1)//在折线图左边下拉框有值的时候并且上面的按钮也按下才绘图
{
changeValueChartAreaByIndex();//通过下拉框的值来改变数组值间接改变图形
chart5.Series["Series5"].Points.DataBindXY(xValues5, yValues5);//绑定数据
}
//chart4.Series["Series4"].LegendText = "偏高";
//System.Diagnostics.Debug.WriteLine("123123");
flagAgeShowPie = 0;
//flagLifeHabitButton = 0;
}好了，这一章主要是列出一些常用的方法分享给大家，下一章我们开始讲我遇到的困难~~
