谁能帮我看一下这段代码，用C#实现图像二值化的时候为什么没有将全部的图片二值化

Question

private void button2_Click(object sender, EventArgs e)
{
{
Color c = new Color();
Bitmap box1 = new Bitmap(pictureBox1.Image);
Bitmap box2 = new Bitmap(pictureBox1.Image);
int rr, lev, wid, x, y, m;
int[] lut = new int[256];
int[, ,] pic = new int[1000, 1000, 10];
lev = 50;
wid = 100;
y = 0;
while (y <= 256)
{
for (x = 0; x <= lev - 1; x++)
{
lut[y] = 255;
y = y + 1;
if (y > 255) goto loop;

}
for (x = 0; x <= wid - 1; x++)
{
lut[y] = 0;
y = y + 1;
if (y > 255) goto loop;
}
}
loop:
for (int i = 0; i < pictureBox1.Width - 1; i++)
{
for (int j = 0; j < pictureBox1.Height - 1; j++)
{
c = box2.GetPixel(i, j);
pic[i, j, 0] = c.R;
pic[i, j, 1] = c.G;
pic[i, j, 2] = c.B;

}
}
for (int i = 0; i < pictureBox1.Width - 1; i++)
{
for (int j = 0; j < pictureBox1.Height - 1; j++)
{
m = pic[i, j, 2];
rr = lut[m];
Color c1 = Color.FromArgb(rr, rr, rr);
box2.SetPixel(i, j, c1);
}

pictureBox2.Image = box2;
}
}
}

        loop:

                {
                    c = box2.GetPixel(i, j);

                }

                pictureBox2.Image = box2;
            }
        }
        //由于图片的高度和宽度与你设置的pictureBox大小一致，故都应为图片的尺寸

请问大神，每次输入图片进行二值化处理的时候，代码能生成成功，但是会报错“索引超出了数组界限”，求解，万分感谢

追答

不会吧，你加上try{。。。}catch{}试试，
。。。为上面图片处理的代码
