此示例显示如何使用Business Objects集合创建报表。Business Objects是一个对象类数据，使用它可以以不同的结构呈现数据：表，列表，数组等。要使用Bisiness对象，您可以使用报表对象的RegBusinessObject（）方法：

private void btDesign_Click(object sender, RoutedEventArgs e){    var stream = System.Reflection.Assembly.GetExecutingAssembly().GetManifestResourceStream(        "UsingBusinessObjects.SimpleList.mrt");     StiReport report = new StiReport();    report.Load(stream);     stream.Close();    stream.Dispose();    stream = null;    report.CalculationMode = StiCalculationMode.Interpretation;    report.RegBusinessObject("Data", "Data", new Data());     report.Design();} private void btPreview_Click(object sender, RoutedEventArgs e){    var stream = System.Reflection.Assembly.GetExecutingAssembly().GetManifestResourceStream(        "UsingBusinessObjects.SimpleList.mrt");     StiReport report = new StiReport();    report.Load(stream);     stream.Close();    stream.Dispose();    stream = null;     report.CalculationMode = StiCalculationMode.Interpretation;    report.RegBusinessObject("Data", "Data", new Data());    report.Render();     report.Show();}

Data()对象包含报表所需的数据结构和数据行：

public class Data{    private List
    
      categoriesItems = new List
     
      ();    public List
      
        Categories    {        get        {            return categoriesItems;        }        set        {            categoriesItems = value;        }    }     public class CategoriesItem    {        private List
       
         products;        public List
        
          Products        {            get            {                return products;            }            set            {                products = value;            }        }         private System.Int32? categoryID;        public System.Int32? CategoryID        {            get            {                return categoryID;            }            set            {                categoryID = value;            }        } ...
