c#只在屏幕的一部分绘制

Elias · 技术社区 · 7 年前

   Console.WriteLine(Screen.PrimaryScreen.Bounds.Width);
   Console.WriteLine(Screen.PrimaryScreen.Bounds.Height);

它记录:1620,1080这是我屏幕大小的一半。。。

下面是我要绘制的代码:

 [DllImport("User32.dll")]
 public static extern IntPtr GetDC(IntPtr hwnd);
 [DllImport("User32.dll")]
 public static extern void ReleaseDC(IntPtr hwnd, IntPtr dc);

 static void Main(string[] args) {
    Console.WriteLine(Screen.PrimaryScreen.Bounds.Width);
    Console.WriteLine(Screen.PrimaryScreen.Bounds.Height);

    IntPtr desktopPtr = GetDC(IntPtr.Zero);
    Graphics g = Graphics.FromHdc(desktopPtr);
    SolidBrush b = new SolidBrush(Color.White);
    g.FillRectangle(b, new Rectangle(0, 0, 16000, 16000));
}

希望有人能帮我,埃利亚斯:)
