winform label文本转换为图片 、Picturebox+label合并转换为图片

  public Form1()

         {

             InitializeComponent();

             //label存入Picturebox

             pictureBox1.Controls.Add(label1);

             pictureBox1.Controls.Add(label2);

         }

         private void button1_Click(object sender, EventArgs e)

         {

             //Picturebox+label合并转换成图片

             foreach (Label l in pictureBox1.Controls)

             {

                 using (Brush brush = new SolidBrush(l.ForeColor))

                 using (Graphics g = Graphics.FromImage(pictureBox1.Image))

                 {

                     Rectangle rect = new Rectangle(l.Left - pictureBox1.Left, l.Top - pictureBox1.Top, l.Width, l.Height);

                     if (l.BackColor != Color.Transparent)

                     {

                         using (Brush bgBrush = new SolidBrush(l.BackColor))

                         {

                             g.FillRectangle(bgBrush, rect);

                         }

                     }

                     g.DrawString(l.Text, l.Font, brush, rect, StringFormat.GenericTypographic);

                 }

             }

             pictureBox1.Image.Save("d:\\abc.png", System.Drawing.Imaging.ImageFormat.Png);

             //文字转换成图片

             //string str =label1.Text;

             //Graphics g = Graphics.FromImage(new Bitmap(1, 1));

             //Font font = new Font("宋体", 9);

             //SizeF sizeF = g.MeasureString(str, font); //测量出字体的高度和宽度

             //Brush brush; //笔刷，颜色

             //brush = new SolidBrush(label1.ForeColor);

             //PointF pf = new PointF(0, 0);

             //Bitmap img = new Bitmap(Convert.ToInt32(sizeF.Width), Convert.ToInt32(sizeF.Height));

             //g = Graphics.FromImage(img);

             //g.DrawString(str, font, brush, pf);

             ////输出图片

             //img.Save("d://123.jpg", System.Drawing.Imaging.ImageFormat.Gif);
