Question

此bugger不起作用，我什至无法检查出什么毛病，因为它无法达到断点。如果在“ Console.WriteLine（“从未到达断点”）;“处设置断点，它不会触发中断。这是简单的代码，但我不知道为什么它不起作用。可能需要更多的睡眠:) ThisPixelCheck函数，如果在某个点找到颜色，则返回true或false。看起来好像没有到达代码。

 void FindPixel()
    {
        int x = 455;
        int y = 1109;
        int found = 0;

        Color findcolor = ColorTranslator.FromHtml("#FFFFFF");

        for (int yplus = 0; yplus > 50; yplus++)
        {
            for (int xplus = 0; xplus > 50; xplus++) 
            {
                Console.WriteLine("breakpoint is never reached");
                var point = new Point(x + xplus, y + yplus);
                var foundpixel = ThisPixelCheck(point, findcolor);
                if (foundpixel)
                {
                    found += 1;
                }
            }
            status_Label.Text = found.ToString() + " pixels found.";
            }

        }

Answer 1

void FindPixel()
{
    int x = 455;
    int y = 1109;
    int found = 0;

    Color findcolor = ColorTranslator.FromHtml("#FFFFFF");

    for (int yplus = 0; yplus < 50; yplus++)
    {
        for (int xplus = 0; xplus < 50; xplus++) 
        {
            Console.WriteLine("breakpoint is never reached");
            var point = new Point(x + xplus, y + yplus);
            var foundpixel = ThisPixelCheck(point, findcolor);
            if (foundpixel)
            {
                found += 1;
            }
        }
        status_Label.Text = found.ToString() + " pixels found.";
        }

    }

for循环是错误的。

Answer 2

 for (int yplus = 0; yplus > 50; yplus++)

此行yplus为零且小于50，因此Programm永远不会进入循环。您应该尝试yplus <50

没有错误，无法在C＃中工作两个嵌套的for循环
