如何直接在.NET代码中快速创建虚拟图像

Question

如何快速创建带有图标大小的随机图像？我既不想使用Image.FromFile，也不想Image.FromStream

Answer 1

int width = 50;
int height = 50;
using (Bitmap bitmap = new Bitmap(width, height))
{

    // do something to the bitmap
    // perhaps use .SetPixel to maybe apply some color

    bitmap.Save("C:\\Temp\\random.bmp");
}
