How can I detect if mouse i hover picturebox control and then to disply or not the picturebox ?

Question

private void pictureBox1_MouseHover(object sender, EventArgs e)
        {
            PictureBox pb = new PictureBox();

            pb.Size = new Size(512, 512);
            pb.Left = (this.ClientSize.Width - pb.Width) / 2;
            pb.Top = (this.ClientSize.Height - pb.Height) / 2;
            pb.BringToFront();

            this.Controls.Add(pb);

            pb.Image = new Bitmap(files[0]);
        }

When the mouse cursor is hover inside pictureBox1 area it's creating and showing the new pb pictureBox control but I want now that if I move the mouse cursor outside the pictureBox1 area then don't display the new pb and over again display pb only when the mouse is inside the pictureBox1 area.

Now when I put the mouse cursor inside pictureBox1 area it will show pb forever no matter if the mouse cursor is inside anymore or not.

@Nedudale , you could try to use Mouse_Leave event to get what you want.

Here is a code example you could refer to.

private void Form1_Load(object sender, EventArgs e)  
        {  
            string path = Path.Combine("D:\\", "1.PNG");  
            pictureBox1.Image = Image.FromFile(path);  
  
        }  
  
        private void pictureBox1_MouseHover(object sender, EventArgs e)  
        {  
            PictureBox pb = new PictureBox();  
            pb.Name = "pic1";  
            pb.SizeMode = PictureBoxSizeMode.StretchImage;  
            pb.Size = new Size(512, 512);  
            pb.Left = (this.ClientSize.Width - pb.Width) / 2;  
            pb.Top = (this.ClientSize.Height - pb.Height) / 2;  
            pb.BringToFront();  
            string path = Path.Combine("D:\\", "2.jpg");  
            pb.Image = new Bitmap(path);  
            this.Controls.Add(pb);  
              
            
        }  
  
        private void pictureBox1_MouseLeave(object sender, EventArgs e)  
        {  
            foreach (Control item in this.Controls)  
            {  
                if(item.Name=="pic1")  
                {  
                    item.Visible = false;  
                }  
            }  
        }
