本文提供了一段用于绘制条形码的C#代码示例，包括如何设置条形码的高度、宽度等属性，并展示了如何将条形码保存为图片文件。

网上找了一下发现大部分都是关于39的，没事就收集了一些其他方式的……

简单代码（有时间上源码）附件下载

 Bitmap image = new Bitmap(image_width, barMaxHeight + ((int)new Font("@宋体", 13).Height));
            
			using (Graphics dc = Graphics.FromImage(image))
			{
				Rectangle bounds = new Rectangle((image.Width-totalImageWidth)/2, 0, totalImageWidth, barMaxHeight);
				Render(barcode, dc, bounds, interGlyphSpace, barMinHeight, barMinWidth, barMaxWidth);
                
                dc.DrawString(text, new Font("@宋体", 13), Brushes.Black, (image.Width-(int)textPosition.Width)/2, image.Height-(int)textPosition.Height,StringFormat.GenericDefault);
			}
            image.Save(@"G:\barcode.png");
			return image;

调用示例：

        private void button1_Click(object sender, EventArgs e)
        {
            BarcodeDraw draw = null;
            draw = InstallBarcodeDraw(draw);
            pictureBox1.Image = draw.Draw(textBox1.Text, 80);
            //x draw.Draw(textBox1.Text,80).Save(@"G:\barcode.png");
        }

        private BarcodeDraw InstallBarcodeDraw(BarcodeDraw draw)
        {
            switch (comboBox1.Text)
            {
                case "Code11C":
                    draw = BarcodeDrawFactory.GetSymbology(BarcodeSymbology.Code11C); break;
                case "Code39NC":
                    draw = BarcodeDrawFactory.GetSymbology(BarcodeSymbology.Code11NC); break;

//省略……

            }
            return draw;
        }

Bitmap image = new Bitmap(image_width, barMaxHeight + ((int)new Font("@宋体", 13).Height));

using (Graphics dc = Graphics.FromImage(image))

{

Rectangle bounds = new Rectangle((image.Width-totalImageWidth)/2, 0, totalImageWidth, barMaxHeight);

Render(barcode, dc, bounds, interGlyphSpace, barMinHeight, barMinWidth, barMaxWidth);

dc.DrawString(text, new Font("@宋体", 13), Brushes.Black, (image.Width-(int)textPosition.Width)/2, image.Height-(int)textPosition.Height,StringFormat.GenericDefault);

}

image.Save(@"G:\barcode.png");

return image;

1 Bitmap image = new Bitmap(image_width, barMaxHeight + (( int ) new Font( " @宋体 " , 13 ).Height));
2
3 using (Graphics dc = Graphics.FromImage(image))
4 {
5 Rectangle bounds = new Rectangle((image.Width - totalImageWidth) / 2 , 0 , totalImageWidth, barMaxHeight);
6 Render(barcode, dc, bounds, interGlyphSpace, barMinHeight, barMinWidth, barMaxWidth);
7
8 dc.DrawString(text, new Font( " @宋体 " , 13 ), Brushes.Black, (image.Width - ( int )textPosition.Width) / 2 , image.Height - ( int )textPosition.Height,StringFormat.GenericDefault);
9 }
10 image.Save( @" G:\barcode.png " );
11 return image;
