这个程序应该制作一个数组，并根据其中的值，它应该绘制不同颜色的点。
首先它创建一个空白地图（数组）。 之后，它会用障碍物填充地图。 最后，它应该在图像框上以图形方式表示障碍，但它不会那样做。
错误是什么？
public partial class Form1 : Form
{
public byte[,] ObstacleGenerator(byte[,] map, byte leftTopX, byte leftTopY, byte rightBottomX, byte rightBottomY)
{
// akadályt építi fel
for (int i = leftTopX; i <= rightBottomX; i++)
{
for (int j = leftTopY; j <= rightBottomY; j--)
{
map[i, j] = 1;
}

return map;
