第C#實現鐘表程序設計本文實例為大家分享了C#實現鐘表程序設計的具體代碼，供大家參考，具體內容如下

工作空間：

代碼如下：

usingSystem;

usingSystem.Collections.Generic;

usingSystem.ComponentModel;

usingSystem.Data;

usingSystem.Drawing;

usingSystem.Linq;

usingSystem.Text;

usingSystem.Windows.Forms;

usingSystem.Diagnostics;

namespace鐘表

publicpartialclassfrmMain:Form

publicfrmMain()

{

InitializeComponent();

}

privatevoidctsmiExit_Click(objectsender,EventArgse)

{

this.Close();

}

privatevoidfrmMain_MouseDown(objectsender,MouseEventArgse)

{

if(e.Button==MouseButtons.Left)

{

flsMouseDown=true;

fDownPosition=e.Location;

//Debug.WriteLine(e.Location);

}

}

privatevoidfrmMain_MouseMove(objectsender,MouseEventArgse)

{

if(flsMouseDown)

{

this.Left=this.Location.X+(e.X-fDownPosition.X);

this.Top=this.Location.Y+(e.Y-fDownPosition.Y);

}

}

privatevoidfrmMain_Mouseup(objectsender,MouseEventArgse)

{

flsMouseDown=false;

}

privatevoidtmrMain_Tick(objectsender,EventArgse)

{

this.Refresh();//調用窗體的Paint事件，根據調制的時間來刷新paint時間

}

privatevoidfDrawDot(GraphicsaGraphics,doubleaValue,intaRadius)//畫出表盤刻度

{

doublelAngle=((360-aValue*6)+90)*Math.PI/180;//根據角度繪畫

PointlPoint=newPoint((int)(200+180*Math.Cos(lAngle)),//刻度所在的為值

(int)(200-180*Math.Sin(lAngle)));

aGraphics.FillEllipse(Brushes.Black,newRectangle(lPoint.X-aRadius,//FillEllipse為內部填充顏色方法，Rectangle為繪畫圓，前倆為圓心坐標，后倆為寬和高

lPoint.Y-aRadius,2*aRadius,2*aRadius));

}

privatevoidfDrawLine(GraphicsaGraphics,doubleaValue,doubleaLength,PenaPen)//畫出時，分，秒的線

{//aValue為角度值，小時12個刻度每個占30°，分和秒60個刻度每個站6°avalue按照的是一個圓分成60個換成角度乘于6

//aLength是指針的長度

doublelAngle=((360-aValue*6)+90)*Math.PI/180;//角度轉化為數值

PointlPoint=newPoint((int)(200+aLength*Math.Cos(lAngle)),//指針線的終點，坐標x，y通過直角三角求得

(int)(200-aLength*Math.Sin(lAngle)));

aGraphics.DrawLine(aPen,newPoint(200,200),lPoint);//繪制倆點連成一條直線，起點相同都為（200,200）

}

privatevoidfrmMain_Paint(objectsender,PaintEventArgse)

{

e.Graphics.SmoothingMode=System.Drawing.Drawing2D.SmoothingMode.HighQuality;//使指針轉動顯得平滑

e.Graphics.DrawImage(this.BackgroundImage,0,0,400,400);//規定表盤的大小和位置

for(inti=0;ii++)

if(i%5==0)fDrawDot(e.Graphics,i,6);//繪制鐘表刻度，大點和小點

elsefDrawDot(e.Graphics,i,2);

DateTimedt=DateTime.Now;//獲取時間

PenpSecond=newPen(Color.Black,2);

PenpMinute=newPen(Color.Red,2);

PenpHour=newPen(Color.Blue,4);

fDrawLine(e.Graphics,((dt.Hour%12)+dt.Minute/60.0)*5,100,pHour);//繪畫時，分，秒指針

fDrawLine(e.Graphics,dt.Minute+dt.Second/60.0,160,pMinute);

fDrawLine(e.Graphics,dt.Second+dt.Millisecond/1000.0,170,pSecond);

}

需添加：（以下代碼）

this.DoubleBuffered=true;

this.Deactivate+=newSystem.EventHandler(this.ctsmiExit_Click);

this.Paint+=newSystem.Windows.Forms.PaintEventHandler(this.frmMain_Paint);

this.MouseDown+=newSystem.Windows.Forms.MouseEventHandler(this.frmMain_MouseDown);
