C# OpenFileDialog Empty

Question

I am trying to get a messagebox if my picturebox is empty.

if (dial == DialogResult.Yes)
{
    if (openfile.FileName == string.Empty)
    {
        MessageBox.Show("Please Upload Poster");
    }
    else
    {
        this.Close();
        poster = openfile.FileName;
    }

}

Me neither, you want a messagebox to show up if user clicks on some button or something while no file uploaded? — , Sep 25 '15 at 08:22

if (pictureBox1.Image != null)
{
    Common.MessageBoxUtilities.WarningMessageBox("You Have Image");
}
else if (pictureBox1.Image == null)
{
    Common.MessageBoxUtilities.WarningMessageBox("You Dont Have Image");
}

Try something like this?

How will this be a difference? Just asking, not flaming – Sep 25 '15 at 08:25

I've been reviewing your answer, it's an automatic resposne. The question was rather poor, but you've just pasted single `if` statement with no explanation whatsoever. – Tarec Sep 25 '15 at 09:38
