调用BarcodeLib


	//生成一维码图片
	 private byte[] GetBarcode(int height, int width, BarcodeLib.TYPE type,
	 string code, out System.Drawing.Image image)
	 {
	 image = null;
	 BarcodeLib.Barcode b = new BarcodeLib.Barcode();
	 b.BackColor = System.Drawing.Color.White;
	 b.ForeColor = System.Drawing.Color.Black;
	 b.IncludeLabel = true;
	 b.Alignment = BarcodeLib.AlignmentPositions.CENTER;
	 b.LabelPosition = BarcodeLib.LabelPositions.BOTTOMCENTER;
	 b.ImageFormat = System.Drawing.Imaging.ImageFormat.Jpeg;
	 System.Drawing.Font font = new System.Drawing.Font("verdana", 10f);
	 b.LabelFont = font;

	 b.Height = height;
	 b.Width = width;

	 try
	 {
	 image = b.Encode(type, code);
	 }
	 catch (Exception e)
	 {
	 MessageBox.Show(e.Message);
	 image = null;
	 }
	 //SaveImage(image, Guid.NewGuid().ToString("N") + ".png");
	 byte[] buffer = b.GetImageData(BarcodeLib.SaveTypes.GIF);
	 return buffer;
	 }

	 //调用
	 private void BuildBarcode()
	 {
	 string number = string.IsNullOrEmpty(textBox1.Text.Trim()) ? "Avx-(13614)-vR" : textBox1.Text.Trim();
	 BarcodeLib.TYPE codeType = comboBox1.SelectedIndex == -1 ? BarcodeLib.TYPE.CODE128 : (BarcodeLib.TYPE)Enum.Parse(typeof(BarcodeLib.TYPE), comboBox1.Text);
	 System.Drawing.Image image;
	 int width = 250, height = 100;
	 byte[] buffer = GetBarcode(height, width,
	 codeType, number, out image);

	 pictureBox1.Image = image;
	 if (image != null)
	 pictureBox1.SizeMode = image.Height > pictureBox1.Height ? PictureBoxSizeMode.Zoom : PictureBoxSizeMode.Normal;
	 }
