System.Argumentexception: 'Invalid parameter. '

Question

I created a button with button24_Click_1 to take printscreen from 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");
    }
}

Follow the problem:

Follow Quickwacth error:

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 image, Rectangle rect) in System.Windows.Forms.PictureBox.Onpaint(Painteventargs pe) 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) in 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)

Coded bmp.Save(); works perfectly, I just can’t add the photo directly to picturebox1. What I did wrong and how to fix ?

Answer 1

I solved the problem, thanks to the comment of @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;
