使用Graphics.DrawLine()方法绘制直线。该方法接受四个参数,前两个参数表示直线的起点坐标,后两个参数表示直线的终点坐标。 graphics.DrawLine(pen, 10, 10, 100, 100); // 在点(10, 10)到点(100, 100)之间绘制一条直线 复制代码 最后,记得释放创建的对象。 pen.Dispose(); // 释放画笔对象
Graphics类中的drawLine(int x1, int y1, int x2, int y2) 方法 这个方法是画一条直线,两点确定一条直线,而在坐标中由横(X)、纵坐标(y)确定一个点,这四参数实际就是确定两个点,是要画的直线的起始点横纵坐标和终点的横纵坐标。 X1,Y1是确定直线的起始点,即横坐标为x1,纵坐标为y1的点。同理x2,y...
