下面这句在Graphics g = Graphics.FromImage(image);这个地方总通不过,请问是怎么回事,谢谢!
        string path = Server.MapPath("./" + TextBox1.Text + "\\" + GridView1.Rows[GridView1.SelectedIndex].Cells[1].Text.ToString());
        System.Drawing.Image image = System.Drawing.Image.FromFile(path);
        System.Drawing.Image copyImage = System.Drawing.Image.FromFile(Server.MapPath("./seal\\sally.jpg"));
        Graphics g = Graphics.FromImage(image);
        g.DrawImage(copyImage, new Rectangle(image.Width - copyImage.Width, image.Height - copyImage.Height, copyImage.Width, copyImage.Height), 0, 0, copyImage.Width, copyImage.Height, GraphicsUnit.Pixel);
        g.Dispose();        string nPath = Server.MapPath("./" + TextBox1.Text + "\\" + GridView1.Rows[GridView1.SelectedIndex].Cells[1].Text.ToString());
        image.Save(nPath);
        image.Dispose();
        if (File.Exists(path))
        {
            File.Delete(path);
        }
        Response.Redirect(nPath);
