I created a button with button24_Click_1 to take printscreen of Form1:

private void button24_Click_1(object sender, EventArgs e)
{
    var frm = new Form1();
    using (var bmp = new Bitmap(frm.Width, frm.Height))
    {
        frm.DrawToBitmap(bmp, new Rectangle(0, 0, bmp.Width, bmp.Height));
        pictureBox1.Image = bmp;
        //bmp.Save(@"C:\Users\Matheus Miranda\Desktop\TESTE\screen.png");
    }
}

Here's the problem:

FollowingisaQuickWactherror:

Message:"Invalid parameter."

ParamName: null

StackTrace: in System.Drawing.Image.get_RawFormat ()      in System.Drawing.Graphics.DrawImage (Image image, Int32 x, Int32 y, Int32 width, Int32 height)      in System.Drawing.Graphics.DrawImage (Image image, Rectangle rect)      in System.Windows.Forms.PictureBox.OnPaint (PaintEventArgs)      in System.Windows.Forms.Control.PaintWithErrorHandling (PaintEventArgs and Int16 layer)      in System.Windows.Forms.Control.WmPaint (Message & m)      in System.Windows.Forms.Control.WndProc (Message & m)      at System.Windows.Forms.Control.ControlNativeWindow.OnMessage (Message & m)      in System.Windows.Forms.Control.ControlNativeWindow.WndProc (Message & m)      in System.Windows.Forms.NativeWindow.DebuggableCallback (IntPtr hWnd, Int32 msg, IntPtr wparam, IntPtr lparam)

With code bmp.Save(); works perfectly, I just can not add the direct photo to picturebox1 . What did I do wrong and how to fix it?

c# winforms

I solved the problem, thanks to the comment from @ Manieiro .

var frm = new Form1();
Bitmap pic = new Bitmap(frm.Width, frm.Height);
Rectangle rect = new Rectangle();
rect = frm.ClientRectangle;
frm.DrawToBitmap(pic, rect);
pictureBox1.Image = pic;
