public partial class WebForm1 : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
}
protected void btnGenerate_Click(object sender, EventArgs e)
{
string barcode = txtCode.Text;
System.Web.UI.WebControls.Image imgBarCode = new System.Web.UI.WebControls.Image();
using (Bitmap bitMap = new Bitmap(barcode.Length * 40, 80))
{
using (Graphics graphics = Graphics.FromImage(bitMap))
{
Font oFont = new Font("IDAutomationHC39M",16);
PointF point = new PointF(2f,2f);
SolidBrush blackBrush = new SolidBrush(Color.Black);
SolidBrush whiteBrush = new SolidBrush(Color.White);
graphics.FillRectangle(whiteBrush, 0, 0, bitMap.Width, bitMap.Height);
graphics.DrawString("*" + barcode + "*", oFont, blackBrush, point);
}
using (MemoryStream ms = new MemoryStream())
{
bitMap.Save(ms, System.Drawing.Imaging.ImageFormat.Png);
byte[] byteImage = ms.ToArray();
Convert.ToBase64String(byteImage);
imgBarCode.ImageUrl = "data:image/png;base64," + Convert.ToBase64String(byteImage);
}
plBarCode.Controls.Add(imgBarCode);
}
}
}
