1.重绘文字
#多行文字
a.先定义一个矩形
Rectangle p1 =new Rectangle(10,0,200,this.Height); Rectangle p2=new Rectangle(210,0,200,this.Height); Rectangle p3=new Rectangle(410,0,100,this.Height);
b.在矩形中写入文字
TextRenderer.DrawText(g,name,Font,p1,ForeColor,TextFormatFlags.HorizontalCenter|TextFormatFlags.VerticalCenter); TextRenderer.DrawText(g, time, Font, p2, ForeColor, TextFormatFlags.HorizontalCenter| TextFormatFlags.VerticalCenter); TextRenderer.DrawText(g, content, Font, p3, ForeColor, TextFormatFlags.HorizontalCenter| TextFormatFlags.VerticalCenter);
#单行文字
a.先定义一个点
Point P1 =new Point(this.Width -100,this.Height -100);
b.在点后写入文字
TextRenderer.DrawText(g,"dsadhskldhashdalks", Font, P1, Color.YellowGreen);
#TextFormatFlags.HorizontalCenter将边框内的文本水平居中对齐 TextFormatFlags.VerticalCenter在边框内部垂直居中对齐文本
2.画线
#画横线
g.DrawLine(new Pen(Color.Brown),0,this.Height-1,this.Width,this.Height-1);//画横线铺满,对于高度不变,横坐标从0到当前宽度,当前高度从-1到-1,就是画出一像素的高度
#画竖线
g.DrawLine(new Pen(Color.Purple),this.Width -15,0,this.Width -15,this.Height -14);//从(-15,0)到(-15,-14)绘制一条竖线,this.Width - 15-----当前宽度从右边减去15像素处开始,this.Height - 14------当前高度从下边减去14像素处开始
#画虚线
privatevoid panel1_Paint(object sender, PaintEventArgs e) { Control P= (Control)sender; Pen pen=new Pen(Color.FromArgb(255,0,0),5); pen.DashStyle= System.Drawing.Drawing2D.DashStyle.Custom;//虚线的样式 pen.DashPattern =newfloat[] {2,2 };//设置虚线中实点和空白区域之间的间隔 Graphics g = e.Graphics; g.DrawLine(pen,0,0,0, P.Height -1); }
#对panel1重绘,this:当前页面为panel1所在的页面
