C# FastReport.NET批量打印条形码报表详解教程

 private Report InitializeReport()
{
    //打印单表数据
    string file = Application.StartupPath + @"\Reports\barcode.frx";
    Report rptUser = new Report();
    rptUser.Load(file);//加载报表模板文件

    //从数据库获取条码数据
    //DataTable dt = CommonData.GetDataDict("tb_Demo_Barcode");

    //生成报表数据源        
    DataTable dt = GenerateTable(100);

    dt.TableName = "M";
    rptUser.RegisterData(dt, "M"); //注册数据源,单表

    //给DataBand(明细数据)绑定数据源
    DataBand band = rptUser.FindObject("Data1") as DataBand;
    DataSourceBase dataSource = rptUser.GetDataSource("M");
    band.DataSource = dataSource;

    return rptUser;
