我正在将“类详细信息”作为数据源附加到报表;

class Detail
{ 
public string Name { get; set; }
public string State { get; set; }
public string City { get; set;}
public List<Transaction> tran { get; set; }
}
class Transaction
{
public string TransactionDate { get; set; }
public string TransactionDescription { get; set; } 
}

并在查询中将其作为List发送。

public List GetAccount(string account) {
List detail = new List();
sql ....
foreach (DataRow dr in dt.Rows)
{
detail.Add(new Detail()
{
  Name= dr["name"].Equals(DBNull.Value) ? string.Empty : dr["name"].ToString(),
 .....
  tran = GetTransactionDetail(account)// calling a list

 }); 
}
return detail;
}

public List<Transaction> GetTransactionDetail(string account)
{
....
}

以及Form1.cs中的

XtraReport1 rep = new XtraReport1();
printControl1.PrintingSystem = rep.PrintingSystem;
var ls = query.GetAccount(accountNo);
rep.DataSource = ls;
rep.CreateDocument();

在报告中我应该得到一个交易明细的列表，
