【Stimulsoft Reports.WinForms教程】在報表中使用Business Objects

---

【下載Stimulsoft Reports.Ultimate最新版本】

此示例顯示如何使用Business Objects集合創(chuàng)建報表。Business Objects：一個對象類數(shù)據(jù)，使用它可以以不同的結(jié)構(gòu)呈現(xiàn)數(shù)據(jù)：表，列表，數(shù)組等。此示例使用Business Objects的兩個變體：IEnumerable和ITypedList：

private void btPreviewIEnumerable_Click(object sender, System.EventArgs e)
{
    StiReport report = new StiReport();
    report.RegData("EmployeeIEnumerable", CreateBusinessObjectsIEnumerable.GetEmployees());
    report.Load("..\\BusinessObjects_IEnumerable.mrt");
    report.Show();
}
 
private void btPreviewITypedList_Click(object sender, System.EventArgs e)
{
    StiReport report = new StiReport();
    report.RegData("EmployeeITypedList", CreateBusinessObjectsITypedList.GetEmployees());
    report.Load("..\\BusinessObjects_ITypedList.mrt");
    report.Show();
}

作為IEnumerable對象使用EmployeeIEnumerable模型，為了填充數(shù)據(jù)，使用CreateBusinessObjectsIEnumerable類的GetEmployees（）方法：

public static EmployeeIEnumerableCollection GetEmployees()
{
    EmployeeIEnumerableCollection employees = new EmployeeIEnumerableCollection();
    Company company = new Company("Company1");
    Department storeDepartment = new Department(company, "Store Department");
    Department salesDepartment = new Department(company, "Sales Department");
 
    EmployeeIEnumerable emp = new EmployeeIEnumerable(storeDepartment, "Nicholas", "Nicholas@company1.com");
    emp.Phones.Add(new Phone("(206) 555-9857"));
    emp.Phones.Add(new Phone("(206) 555-6546"));
    emp.Phones.Add(new Phone("(206) 555-7651"));
    employees.Add(emp);
 
    emp = new EmployeeIEnumerable(storeDepartment, "Margaret", "Margaret@company1.com");
    emp.Phones.Add(new Phone("(206) 555-4546"));
    emp.Phones.Add(new Phone("(206) 555-0110"));
    employees.Add(emp);
 
    emp = new EmployeeIEnumerable(storeDepartment, "Janet", "Janet@company1.com");
    emp.Phones.Add(new Phone("(206) 555-5462"));
    emp.Phones.Add(new Phone("(206) 555-8400"));
    emp.Phones.Add(new Phone("(206) 555-9842"));
    employees.Add(emp);
 
    emp = new EmployeeIEnumerable(salesDepartment, "Laura", "Laura@company1.com");
    emp.Phones.Add(new Phone("(206) 555-0022"));
    employees.Add(emp);
 
    emp = new EmployeeIEnumerable(salesDepartment, "Mark", "Mark@company1.com");
    emp.Phones.Add(new Phone("(206) 555-9980"));
    emp.Phones.Add(new Phone("(206) 555-5567"));
    employees.Add(emp);
 
    emp = new EmployeeIEnumerable(salesDepartment, "Michael", "Michael@company1.com");
    emp.Phones.Add(new Phone("(206) 555-5642"));
    employees.Add(emp);
 
    emp = new EmployeeIEnumerable(salesDepartment, "Thomas", "Thomas@company1.com");
    emp.Phones.Add(new Phone("(206) 555-8949"));
    employees.Add(emp);
 
    return employees;
}

作為ITypedList對象使用EmployeeITypedList模型，為了填充數(shù)據(jù)，使用CreateBusinessObjectsITypedList類的GetEmployees（）方法：

public static EmployeeITypedListCollection GetEmployees()
{
    EmployeeITypedListCollection employees = new EmployeeITypedListCollection();
    Company company = new Company("Company1");
    Department storeDepartment = new Department(company, "Store Department");
    Department salesDepartment = new Department(company, "Sales Department");
 
    EmployeeITypedList emp = new EmployeeITypedList(storeDepartment, "Nicholas", "Nicholas@company1.com");
    emp.Phones.Add(new Phone("(206) 555-9857"));
    emp.Phones.Add(new Phone("(206) 555-6546"));
    emp.Phones.Add(new Phone("(206) 555-7651"));
    employees.Add(emp);
 
    emp = new EmployeeITypedList(storeDepartment, "Margaret", "Margaret@company1.com");
    emp.Phones.Add(new Phone("(206) 555-4546"));
    emp.Phones.Add(new Phone("(206) 555-0110"));
    employees.Add(emp);
 
    emp = new EmployeeITypedList(storeDepartment, "Janet", "Janet@company1.com");
    emp.Phones.Add(new Phone("(206) 555-5462"));
    emp.Phones.Add(new Phone("(206) 555-8400"));
    emp.Phones.Add(new Phone("(206) 555-9842"));
    employees.Add(emp);
 
    emp = new EmployeeITypedList(salesDepartment, "Laura", "Laura@company1.com");
    emp.Phones.Add(new Phone("(206) 555-0022"));
    employees.Add(emp);
 
    emp = new EmployeeITypedList(salesDepartment, "Mark", "Mark@company1.com");
    emp.Phones.Add(new Phone("(206) 555-9980"));
    emp.Phones.Add(new Phone("(206) 555-5567"));
    employees.Add(emp);
 
    emp = new EmployeeITypedList(salesDepartment, "Michael", "Michael@company1.com");
    emp.Phones.Add(new Phone("(206) 555-5642"));
    employees.Add(emp);
 
    emp = new EmployeeITypedList(salesDepartment, "Thomas", "Thomas@company1.com");
    emp.Phones.Add(new Phone("(206) 555-8949"));
    employees.Add(emp);
 
    return employees;
}
