MDICSharp案例总结：

1、 MDI窗体IsMdiContainer属性设置为true

2、 MainMenu、toolBarButton、ImageList工具控件等设计

顶级菜单MdiList属性设置为True，则显示所有子窗口及选中当前子窗口

ImageList需准备好图片

toolBar需先选择要用到的ImageList，然后设置Buttons属性，打开Buttons属性对话框，给每个toolBarButton选择ImageIndex

toolBar_Click单击函数：

private void toolBar1_ButtonClick(object sender, System.Windows.Forms.ToolBarButtonClickEventArgs e)    {        switch (toolBar1.Buttons.IndexOf(e.Button))        {            case 0 :                mnuFileNew_Click(null, null);                break;            case 1 :                mnuFileExit_Click(null,null);                break;        }}

3、文件：打开文件、保存文件,在这个地方是对应的两个操作

public void miOpen_Click(object sender, System.EventArgs e){        OpenFileDialog openFileDialog = new OpenFileDialog();         if (openFileDialog.ShowDialog() == DialogResult.OK)        {            filename = openFileDialog.FileName;            currentFilename = filename;            Stream openStream = openFileDialog.OpenFile();            if (openStream != null)            {BinaryFormatter formatter = new BinaryFormatter();            shapesArr = (ArrayList) formatter.Deserialize(openStream);            openStream.Close();            // allow shapes to be displayed            bDrawAllowed = true;            // reset shape type            currShape = ShapeType.cursor;            this.Refresh();            } // if().        } // if(). } // miOpen_Click().

public void miSave_Click(object sender, System.EventArgs e){SaveFileDialog saveFileDialog = new SaveFileDialog();String filename;     if (saveFileDialog.ShowDialog() == DialogResult.OK){      filename = saveFileDialog.FileName;}if (filename == null) return;        else        {            Stream saveStream ;            saveStream = File.OpenWrite(filename);            if (saveStream != null)            {                BinaryFormatter formatter = new BinaryFormatter();                             // serialize shapes                formatter.Serialize(saveStream, shapesArr);                saveStream.Close();            } // if().} // else.}

4、对话框：MessageBox对话框、Color对话框

MessageBox.Show(this,"No changes!", "Error: Empty Canvas",

MessageBoxButtons.OK, MessageBoxIcon.Error);

MessageBox.Show(string question,"Save File?", MessageBoxButtons.YesNo) == DialogResult.Yes

ColorDialog:

Color color;

ColorDialog dlg = new ColorDialog();

if (dlg.ShowDialog() == DialogResult.OK)

{

color = dlg.Color;

m_pen = new Pen(color);

m_brush = new SolidBrush(color);

}

5、 DrawLine、DrawTriangle、DrawRectangle、DrawEllipse等画图形函数

***:    Rectangle drawArea;    Size rectSize = new Size((EndPoint.X - StartPoint.X), (EndPoint.Y - StartPoint.Y));    drawArea = new Rectangle(StartPoint, rectSize); public override void DrawShape(Graphics dc, Pen drawPen, Brush brush){  //***  //Brush b =  new SolidBrush(Color.Red);  dc.DrawLine(drawPen, StartPoint, EndPoint);} public override void DrawShape(Graphics dc, Pen drawPen, Brush brush){  ***  Brush b =  new SolidBrush(Color.Red);  dc.DrawRectangle(drawPen, drawArea);  dc.FillRectangle(brush, drawArea);} public override void DrawShape(Graphics dc, Pen drawPen, Brush brush){  ***  dc.DrawEllipse(drawPen, drawArea);  dc.FillEllipse(brush, drawArea);}    public override void DrawShape(Graphics dc, Pen drawPen, Brush brush){  ***  Brush b =  new SolidBrush(Color.Red);  Point[] pt;  pt = new Point[4];           pt[0].X = pt[3].X = EndPoint.X;  pt[0].Y = pt[3].Y = EndPoint.Y;           pt[1].X = StartPoint.X + rectSize.Width/2;  pt[1].Y = StartPoint.Y;       pt[2].X = StartPoint.X;  pt[2].Y = EndPoint.Y;   dc.DrawPolygon(drawPen, pt);  dc.FillPolygon(brush, pt);}

6、 C#类库

using system;

using system.Drawing; —— 画图形

using system.IO; —— 流、文件

using system.Collections; —— 集合、Arraylist

using system.Windows.Forms;

using system.Runtime.Serialization.Formatters.Binary; —— BinaryFormatter
