根据您的代码,您可以使用 System.Drawing 在图像上打印文本:
Zen.Barcode.Code128BarcodeDraw barcode = Zen.Barcode.BarcodeDrawFactory.Code128WithChecksum;
var image = barcode.Draw(textBox1.Text, 50);
using (var graphics = Graphics.FromImage(image))
using (var font = new Font("Consolas", 12)) // Any font you want
using (var brush = new SolidBrush(Color.White))
using (var format = new StringFormat() { LineAlignment = StringAlignment.Far }) // To align text above the specified point
{
// Print a string at the left bottom corner of image
graphics.DrawString(textBox1.Text, font, brush, 0, image.Height, format);
}
pictureBox1.Image = image;
有点不清楚数据库与您问题的第一部分的关系。
更新。
哦,我没有注意到生成的条形码图是整个图像。在这种情况下,您可以在较大的图像上绘制条形码和文本:
Zen.Barcode.Code128BarcodeDraw barcode = Zen.Barcode.BarcodeDrawFactory.Code128WithChecksum;
var barcodeImage = barcode.Draw(textBox1.Text, 50);
var resultImage = new Bitmap(barcodeImage.Width, barcodeImage.Height + 20); // 20 is bottom padding, adjust to your text
using (var graphics = Graphics.FromImage(resultImage))
using (var font = new Font("Consolas", 12))
using (var brush = new SolidBrush(Color.Black))
using (var format = new StringFormat()
{
Alignment = StringAlignment.Center, // Also, horizontally centered text, as in your example of the expected output
LineAlignment = StringAlignment.Far
})
{
graphics.Clear(Color.White);
graphics.DrawImage(barcodeImage, 0, 0);
graphics.DrawString(textBox1.Text, font, brush, resultImage.Width / 2, resultImage.Height, format);
}
pictureBox1.Image = resultImage;
