CSharp生成二维条码的步骤
一、Demo和控件下载
打开http://www.FzBozc.com/CSharp.html下载 客户端演示DEMO到本地，并进行解压打开。
DEMO采用VS2010开发，需要FrameWork4.0开发。
二、类库引用
将下载的类库COPY到开发目录下，点击VS下的“引用”右键，选择“添加引用”，将类库引用到程序中。
根据分页参数设置，将设置的参数写入对应条码参数对象中。
private EncodingOptions GetOption(int nType = 0)
{
EncodingOptions options;
if(nType == 0) //PDF417
{
FzBozc.PDF417.PDF417EncodingOptions pdf =
newFzBozc.PDF417.PDF417EncodingOptions();
pdf.Aspect =DDL_Aspect.SelectedValue;
pdf.Compact =Chk_Compact.Checked;
pdf.Cols =ToInt(TB_Cols.Text);
pdf.Rows = ToInt(TB_Rows.Text);
pdf.XScale =ToInt(DDL_XScale.SelectedValue);
pdf.YScale =ToInt(DDL_YScale.SelectedValue);
pdf.ErrorCorrection =(FzBozc.PDF417.Internal.PDF417ErrorLevel)ToInt(DDL_EccPDF.SelectedValue);
options = pdf;
}
elseif (nType == 1) //Qr_Code
{
FzBozc.QrCode.QrCodeEncodingOptions qr =new FzBozc.QrCode.QrCodeEncodingOptions();
qr.MdScale =ToInt(DDL_Scale.SelectedValue);
if(DDL_EccQR.SelectedValue =="L")qr.ErrorCorrection = FzBozc.QrCode.Internal.QrErrorLevel.L;
elseif (DDL_EccQR.SelectedValue =="M") qr.ErrorCorrection =FzBozc.QrCode.Internal.QrErrorLevel.M;
elseif (DDL_EccQR.SelectedValue =="H") qr.ErrorCorrection =FzBozc.QrCode.Internal.QrErrorLevel.H;
elseqr.ErrorCorrection = FzBozc.QrCode.Internal.QrErrorLevel.Q;
options = qr;
}
elseif (nType == 2) //DataMatrix
{
FzBozc.Datamatrix.DatamatrixEncodingOptions dm =new FzBozc.Datamatrix.DatamatrixEncodingOptions();
dm.MdScale =ToInt(DDL_Scale.SelectedValue);
options = dm;
}
else //Aztec
{
FzBozc.Aztec.AztecEncodingOptions azt =new FzBozc.Aztec.AztecEncodingOptions();
azt.MdScale =ToInt(DDL_Scale.SelectedValue);
azt.ErrorCorrection =ToInt(TB_EccPercent.Text);
options = azt;
}
options.Width =ToInt(TB_Width.Text);
options.Height = ToInt(TB_Height.Text);
return(EncodingOptions)options;
｝
四. 生成条码
根据参数设置和条码内容，生成条码。
条码需要保存到服务端对应的目录下，如“BarImage”目录
网站目录要具有写入权限。
protectedvoid Btn_Create_Click(object sender,EventArgse)
{
try
{
intk = DDL_BarType.SelectedIndex;
BarcodeFormatfmtBarCode = BarcodeFormat.PDF_417;
if(k == 1) fmtBarCode = BarcodeFormat.QR_CODE;
if(k == 2) fmtBarCode = BarcodeFormat.DATA_MATRIX;
if(k == 3) fmtBarCode =BarcodeFormat.AZTEC;
EncodingOptionsBarOptions = GetOption(k);
varwriter = new BarcodeWriter
{
Format = fmtBarCode,
Options = BarOptions
};
System.Drawing.Image img= writer.Write(TB_Info.Text);
//输出图像
stringfilename = Guid.NewGuid().ToString() +".jpg";
stringfilepath =Server.MapPath(@"~\BarImage")+"\\" + filename;
System.IO.FileStream fs =newSystem.IO.FileStream(filepath, System.IO.FileMode.OpenOrCreate, System.IO.FileAccess.Write);
img.Save(fs,System.Drawing.Imaging.ImageFormat.Jpeg);
fs.Close();
pictBar.ImageUrl ="BarImage/"+ filename;
pictBar.Width = img.Width;
pictBar.Height = img.Height;
img.Dispose();
}
catch(Exception ex )
{
Response.Write("");
}
}
｝
