在RDLC嵌套列表对象绑定对象数据源

我知道我们可以对象数据源绑定到RDLC。我想绑定的对象一样如下：

I know we can bind object data source to RDLC. I am trying to bind an object like as follows:

public class ContactReportData
{
   public string ContactReportHeading{get;set;}
   public string ContactReportSubHeading{get;set;}
   public List<Contact> ContactDetails{get;set;}
}

public class Contact    {
   public string ContactName{get;set;}
   public string ContactDesignation{get;set;}
}

虽然设置为RDLC，它会发现一次只能有一个数据集，说ContactReportData （无接触的清单）或联系人。我想这是因为报表需要它是那样

While Setting to RDLC, it will find only one dataset at time, say ContactReportData (without the list of contact) OR Contact. I guess that is because the report needs it to be in that way.

我想要的是有报告显示的数据：
ContactReportHeading
ContactReportSubHeading
表格在联系人的形式 - 联系人姓名，名称

What I want is to have the data shown in report as : ContactReportHeading ContactReportSubHeading tabular form of Contacts in - Contact Name, Designation.

我可以给本作的报告数据为静态的细节，只有绑定联系人列表，但我已经是接触报告，我一个面临的问题列表。

I could have given this as the details of report data as static and only bind the contacts list, but what I have is list of contact reports where I a facing the issue.
