推荐答案

将图像读入Bitmap对象，并传递文件名.您可以使用Bitmap.LockBits方法访问像素数据.访问后，完成Bitmap.UnlockBits.

如果您确实需要读取标题，则将需要FileStream对象和很多勇气. http://www.libpng.org/pub/png/spec/ [

Read the image into a Bitmap object passing it the filename. You can access the pixel data using the method Bitmap.LockBits. After accessing, finish with Bitmap.UnlockBits.

If you really need to read the header, you''ll need a FileStream object and a lot of courage. http://www.libpng.org/pub/png/spec/[^]
