使用LINQ将对象构建为对象

Question

我正在尝试使用来自类的数据来生成XML文件，该类具有与名称关联的名称和多个地址。我迷路了@向XElement添加了多个地址。 有人可以帮我。 在此先感谢 BB。

我的课表：

    public class Subject 
    { 
     public ClueName name { get; set; } 
     public List driverAddress { get; set;} 
    } 


public class DriverAddress 
    { 
     public string house { get; set; } 
     public string street1 { get; set; } 
     public string city { get; set; } 
     public string state { get; set; } 
     public string zip4 { get; set; } 
    } 

private string BuildRequestXML(List <Subject> input) 
     { 
      string subjectId = "S1" ; 
      XElement req = new XElement("order", 
           new XElement("order_dataset", 
            new XElement("subjects", 
             from i in input 
             select 
             new XElement("subject", new XAttribute("id", subjectId), 
              new XElement("name", 
                 new XElement("first",i.name.first), 
                 new XElement("middle", i.name.middle), 
                 new XElement("last", i.name.last) 
                 ) 
                ) 
               ), 
              new XElement("addresses", 
               input.Select(c => {c.driverAddress.Select (d => 
                new XElement("address",         
                new XElement("street1",d.street1), 
                new XElement("city",d.city), 
                new XElement("state",d.state), 
                new XElement("postalcode",d.postalcode) 
                )).ToList(); 
                }).ToList() 
                 ) 
              ) 
            ); 
     }

我认为这个问题是在input.Select(c => {c.driverAddress.Select (d =>部分。

您已经迭代虽然输入作为我，这样可以沿

from d in i.driverAddress 
select new XElement("address", 
      new XElement("street1", d.Street1), 
      new XElement("street2", d.Street2), 

等线路做...

更新：由于驱动程序的地址不应该是输出为主题的儿童，请尝试以下操作：

var addresses = new List<DriverAddress>(); 
input.ForEach(delegate(Subject s) { s.driverAddress.ForEach(d => addresses.Add(d)); }); 


string subjectId = "S1"; 
XElement req = new XElement("order", 
    new XElement("order_dataset", 
     new XElement("subjects", 
      from i in input 
      select 
      new XElement("subject", new XAttribute("id", subjectId), 
       new XElement("name", 
        new XElement("first", i.name.first), 
        new XElement("middle", i.name.middle), 
        new XElement("last", i.name.last) 
       ) 
      ) 
     ), 
     new XElement("addresses", 
       from d in addresses 
       select new XElement("address", 
         new XElement("street1", d.street1), 
         new XElement("city", d.city), 
         new XElement("state", d.state), 
         new XElement("postalcode", d.postalcode) 
       ) 
     ) 

    ) 
);
