实验2-4：编程进行卡布列克运算。所谓卡布列克运算，是指任意一个四位数，只要它们各个位上的数字不全相同，就有这样的规律：
1） 把组成这个四位数的四个数字由大到小排列，形成由这四个数字构成的最大数字
2） 把组成这个四位数的四个数字由小到大排列，形成由这四个数字构成的最小的四位数
3） 求出以上两数之差，得到一个新的四位数

实验3-3：假设某银行共发出M张储蓄卡，每张储蓄卡拥有唯一的卡号，每天每张储蓄卡至多支持储蓄卡持有者的N笔“存款”或“取款”业务。根据实际发生的业务，实际处理数据，以反映最新情况。
设Card卡包含的数据域有：卡号，当前余额，允许当日发生的业务次数（定义成静态变量，为所有Card类所共享），当日实际发生的业务数以及一个数组记录发生的具体业务，它提供的主要方法是store，处理判断是否超过当日允许发生的最大笔数，当前余额是否足以取款以及实现修改当前数据等。
当持卡者输入正确的卡号、存款或取款金额后，程序进行相应的处理。若是输入了不正确的数据，程序会提示持卡者重新输入；若输入的卡号为负数时，银行终止当日业务。

实验七：GDI+编程
实验目的：
1） 创建Graphics对象；
2） 使用Graphics对象绘制线条和形状、呈现文本或显示与操作图像
实验内容：
实验7-1：创建Graphics对象，使用Graphics对象绘制线条和形状
主要相关代码：
1. 添加一个按钮，双击按钮，添加绘图程序
private void button1_Click(object sender, EventArgs e)
{
Graphics myGra = this.CreateGraphics();
Pen mypen1 = new Pen(Color.Red, 2);
myGra.DrawLine(mypen1, 100, 0, 300, 500);//直线
Pen mypen2 = new Pen(Color.Orange, 2);
myGra.DrawEllipse(mypen2, 100, 100, 60, 60);//圆形
myGra.DrawEllipse(mypen2, 200, 100, 60, 120);//椭圆形
Pen mypen3= new Pen(Color.Yellow , 3);
myGra.DrawRectangle (mypen3, 123, 234, 60, 60);//正方形
myGra.DrawRectangle(mypen3, 223, 234, 60, 120);//任意矩形
//自定义多边形
Point[] myPoint = new Point[4];
myPoint[0].Y = 100;
myPoint[1].X = 200;
myPoint[1].Y = 20;
myPoint[2].X = 300;
myPoint[2].Y = 100;
myPoint[3].X= 123;
myPoint[3].Y = 234;
Pen mypen20 = new Pen(Color.Aqua);
myGra.DrawPolygon(mypen20, myPoint);
}
2. 添加两个按钮，实现清除和文本测试
private void button3_Click(object sender, EventArgs e)
{
Graphics fontGra = this.CreateGraphics();
Font myFont = new Font("楷体_GB2312", 24);
Brush myBr = new SolidBrush(Color.Red);
fontGra.DrawString(button_Font.Text, myFont, myBr, new Point(200, 200));
}
private void button2_Click(object sender, EventArgs e)
{

clearG.Clear(Color.White);

实验8-2：建立一个简单的学生成绩浏览界面
主要相关代码：
1. 为窗体类添加一个控制按钮状态的方法：
private void ButtonStateControl()
{
btnFirst.Enabled = true;
btnNext.Enabled = true;
btnPrev.Enabled = true;
btnLast.Enabled=true;
if (this.BindingContext[mDataSet, "Student.Student_Course"].Position == 0)
{
btnPrev.Enabled = false;
btnFirst.Enabled = false;
}
if (this.BindingContext[mDataSet, "Student.Student_Course"].Position ==
(this.BindingContext[mDataSet, "Student.Student_Course"].Count - 1))
{
btnNext.Enabled = false;
btnLast.Enabled = false;
}
}
2． 由于在窗体打开时就需要设定按钮状态，所以在窗体的Load事件中调用此方法
private void Form2_Load(object sender, EventArgs e)
{
ButtonStateControl();
}
3． 对数据集导航的四个按钮进行编码实现记录指针的移动
private void btnFirst_Click(object sender, EventArgs e)
{
this.BindingContext[mDataSet, "Student.Student_Course"].Position=0;
ButtonStateControl();
}
private void btnPrev_Click(object sender, EventArgs e)
{
this.BindingContext[mDataSet, "Student.Student_Course"].Position -= 1;
ButtonStateControl();
}
private void btnLast_Click(object sender, EventArgs e)
{
this.BindingContext[mDataSet, "Student.Student_Course"].Position = this.BindingContext[mDataSet, "Student.Student_Course"].Count - 1;
ButtonStateControl();
}
private void btnNext_Click(object sender, EventArgs e)
{
this.BindingContext[mDataSet, "Student.Student_Course"].Position += 1;
ButtonStateControl();
}
4． 为主窗口Load事件添加代码
private void Form1_Load(object sender, EventArgs e)
{
daStudent.Fill(dataSet11);
daScore.Fill(dataSet11);
frmScore = new Form2();
frmScore.mDataSet = dataSet11;
frmScore.BindingContext = this.BindingContext;
frmScore.txtCourse.DataBindings.Add("Text",dataSet11,"Student.Student_Course.课程名称");
frmScore.txtScore.DataBindings.Add("Text", dataSet11, "Student.Student_Course.成绩");
frmScore.Text = "成绩明细:" + dgStudent[dgStudent.CurrentCell.RowNumber,1].ToString();
}
5． 当用户点击“查看成绩”按钮时弹出明细窗口，设置该按钮的事件处理代码
private void button1_Click(object sender, EventArgs e)
{
frmScore.ShowDialog(this);
}
