GetPixel(ScreenWidth,ScreenHeight)抛出异常

Question

我有一台1080P显示器.干

int j Screen.PrimaryScreen.Bounds.Width;
int k = Screen.PrimaryScreen.Bounds.Height;
_Bitmap.GetPixel(j, k).GetBrightness();

(_Bitmap大小等于我的屏幕边界),它抛出一个异常,说"参数必须为正且<height".

Answer 1

Width和Height从1开始计数,GetPixel()中使用的索引从0开始.因此,当尝试以(宽度,高度)访问Pixel时,找不到任何内容

要更正错误,请将代码更改为(例如):

int width = Screen.PrimaryScreen.Bounds.Width;
int height = Screen.PrimaryScreen.Bounds.Height;

_Bitmap.GetPixel(width-1,height-1).GetBrightness();
