我有一个面板和一个按钮。即:
private void button1_Click(object sender, EventArgs e)
{
panel2.Paint += new PaintEventHandler(panel2_Paint);
panel2.Refresh();
}
和
private void panel2_Paint(object sender, PaintEventArgs e)
{
Graphics g = this.CreateGraphics();
Graphics[,] g1 = new Graphics[140, 140];
int[,] graph = new int[140, 140];
int i, j;
for (i = 0; i < 140; i++)
for (j = 0; j < 140; j++)
{
graph[i, 8] = 1;
graph[i, 10] = 1;
}
Pen p = new Pen(Color.Blue);
SolidBrush mySolidColorBrush = new SolidBrush(Color.Blue);
Graphics a;
a = this.CreateGraphics();
for (i = 1; i <= 10; i++)
for (j = 1; j <= 14; j++)
{
g.DrawEllipse(p, 80 * i, 80 * j, 10, 10);
g.FillEllipse(mySolidColorBrush, 80 * i, 80 * j, 20, 20);
a.DrawLine(Pens.Blue, 80 * i, 80 * j, 80 * (i - 1), 80 * (j - 1));
}
}
当我点击按钮时,输出应显示在面板上,但在我的情况下,它会显示在表格上。
