条码打印

最近的工程要求条码打印~~咱用了简单的方法，直接调用条码对象生成图像打印--

using System;
using System.Collections.Generic;
using System.Text;
    /// <summary>
    /// 打印编码
    /// </summary>
    public sealed class PrintBarcode
    {
        BarcodeLib.Barcode _Barcode;
        public PrintBarcode()
        {

            _Barcode = new BarcodeLib.Barcode();
            _Barcode.IncludeLabel = true;
        }

        public System.Drawing.Image Fill(string BarcodeText)
        {
            //---12  或者13 长度   的时候用BarcodeLib.TYPE.EAN13这个编码占小嘿嘿
            if (BarcodeText.Length >= 12 && BarcodeText.Length <= 13)
            {
                return _Barcode.Encode(BarcodeLib.TYPE.EAN13, BarcodeText, 100, 50);
            }


             //-------------------这里可以适应小于13位置
             return _Barcode.Encode(BarcodeLib.TYPE.CODE128, BarcodeText, 100,50);
        }



    }

再输出就行了哈，输出的时候用pb.Fill适配条码文本~~

BLL.PrintBarcode pb = new PrintBarcode();

        /// <summary>
        /// 打印事件
        /// </summary>
        /// <param name="sender"></param>
        /// <param name="e"></param>
        private void pd_PrintPage(object sender, PrintPageEventArgs e)
        {
            //---循环打印消息开始打印
            for (int Index = PrintIndex; Index < MessingList.PrintMessing.Count; Index++)
            {
                IPrintMessing TempMessing = MessingList.PrintMessing[Index];


                //---字体大小
                int FontSize = MessingList.StyleList.Style[TempMessing.Id].FontSize;
                
                //----特殊码处理
                if (MessingList.StyleList.Style[TempMessing.Id].Type == PrintStyleType.Barcode)
                {

                    e.Graphics.DrawImage(pb.Fill(TempMessing.PrintValue), new System.Drawing.Point(TempMessing.Print_X, TempMessing.Print_Y));
                
                }
                else
                {
                    e.Graphics.DrawString(TempMessing.PrintValue, new System.Drawing.Font(new System.Drawing.FontFamily("黑体"), FontSize),
                        System.Drawing.Brushes.Black, TempMessing.Print_X, TempMessing.Print_Y);
                }
                    ////--打印后判断是否是该页结束
                if (TempMessing.isPageEnd)
                {
                    if (Index >= MessingList.PrintMessing.Count - 1)
                    {
                        //---最后一页从新设置
                        PrintIndex = 0;
                        return;
                    }
                    else
                    {
                        //---重新在执行pd_PrintPage事件
                        e.HasMorePages = true;


                        //---负值给打印打印指针,跳过当前索引
                        PrintIndex = Index + 1;

                        //---判断一页结束
                        //----跳出循环
                        return;
                    }
                }




            }
