.NET 一维、二维码生成DEMO

条码技术越来越流行，已经不再局限于物流、超市等专业行业了，很多网站都已经加上了二维码，作为代码民工们，怎么能不懂得用这门技术呢。

在网上找了一些资料，一维码生成的源码相对较多，也可用，二维码的也不少，但我发现找来找去都是同一个DEMO，而且跑不动，晕死，后来找到了QrCodeNet的源码才搞掂。

关键代码如下：

一维码生成(调用BarcodeLib)：

[csharp]
//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; 
}     

        //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.No
