將數據表示數據反映到類對象中C＃

Question

我是在C＃中使用反射的新手段。我昨天發佈了一個關於如何將數據表中的數據反映到類對象的問題。這個問題得到了回答，它的工作完美。我現在的問題是我有兩個類需要從2個不同的數據表中設置對象。我有一個發送類和一個狀態類。發送可以有很多狀態，所以它是一對多的關係。這是我在發送類中的變量：

 private string _Barcode; 
     private string _Barcode2; 
     private DateTime _PickupDate; 
     private string _PickupCustomer; 
     private string _PickupName; 
     private string _PickupStreet; 
     private string _PickupHouseNo; 
     private string _PickupPostal; 
     private string _PickupCity; 
     private string _PickupCountry; 

     private DateTime _DeliveryDate; 
     private string _DeliveryCustomer; 
     private string _DeliveryName; 
     private string _DeliveryStreet; 
     private string _DeliveryHouseNo; 
     private string _DeliveryPostal; 
     private string _DeliveryCity; 
     private string _DeliveryCountry; 

     private int _Coli; 
     private double _Weight; 
     private double _Volumen; 

     private List<StatusHistory> _StatusHistory = new List<StatusHistory>(); 

每個變量都有一個get和set函數。

這是我的狀態類的變量：

private int _SendingID; 
private string _DanxCode; 
private string _RecpName; 
private int _Logtime; 

這是我的方法用於反射從數據表中的數據類對象：

public static IList<Sending> ReflectData<Sending>(DataTable sendingList, DataTable statusList) 
     { 
      List<Sending> list = Activator.CreateInstance<List<Sending>>(); 
      Sending sendingInstance = Activator.CreateInstance<Sending>(); 
      var property = sendingInstance.GetType().GetProperties(BindingFlags.DeclaredOnly | BindingFlags.Public | BindingFlags.Instance); 
      foreach (DataRow dr in sendingList.Rows) 
      { 
       Sending ins = Activator.CreateInstance<Sending>(); 
       foreach (var p in property) 
       { 
        try 
        { 
         p.SetValue(ins, dr[p.Name], null); 
        } 
        catch (Exception e) 
        { 
         Console.WriteLine(e.Message); 
        } 
       } 
       DataRow[] row = statusList.Select("SendingID = " + dr[0]); 
       List<Status> sh = Activator.CreateInstance<List<Status>>(); 
       foreach (DataRow r in row) 
       { 
        Status statusInstance = Activator.CreateInstance<Status>(); 
        var porpsh = statusInstance.GetType().GetProperties(BindingFlags.DeclaredOnly | BindingFlags.Public | BindingFlags.Instance); 
        foreach (var psh in porpsh) 
        { 
         try 
         { 
          psh.SetValue(statusInstance, r[psh.Name], null); 
         } 
         catch { } 
        } 
       } 
       list.Add(ins); 
      } 
      return list; 
     } 

我需要的結果包含發送（發貨）與屬於發送的相關4狀態'。

結果運行，這是當我得到沒有地位什麼那麼但在這裏它是：

<ArrayOfSending xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns="http://danx.com/"> 
<Sending> 
<Barcode>SE140</Barcode> 
<Barcode2>SE140</Barcode2> 
<PickupDate>2014-02-13T00:00:00</PickupDate> 
<PickupName>Parts Europe</PickupName> 
<PickupStreet>xxxx</PickupStreet> 
<PickupHouseNo>1</PickupHouseNo> 
<PickupPostal>xxxxx</PickupPostal> 
<PickupCity>xxxxx</PickupCity> 
<PickupCountry>xxxx</PickupCountry> 
<DeliveryDate>2014-03-18T12:00:00</DeliveryDate> 
<DeliveryName>Bil AB</DeliveryName> 
<DeliveryStreet>zzzzz</DeliveryStreet> 
<DeliveryHouseNo>39</DeliveryHouseNo> 
<DeliveryPostal>zzzzz</DeliveryPostal> 
<DeliveryCity>zzzzz</DeliveryCity> 
<DeliveryCountry>zzzzzz</DeliveryCountry> 
<Coli>1</Coli> 
<Weight>1</Weight> 
<Volumen>0.05</Volumen> 
<StatusHistory/> 
</Sending> 
</ArrayOfSending> 

希望你們能幫助我。

找到解決我的問題。這是解決方案。

public static IList<Sending> ReflectData(DataTable sendingList, DataTable statusList) 
{ 
    List<Sending> list = Activator.CreateInstance<List<Sending>>(); 
    var property = typeof(Sending).GetProperties(BindingFlags.DeclaredOnly | BindingFlags.Public | BindingFlags.Instance); 
    foreach (DataRow dr in sendingList.Rows) 
    { 
     Sending sendingInstance = Activator.CreateInstance<Sending>(); 
     foreach (var p in property) 
     { 
      try 
      { 
       p.SetValue(sendingInstance, dr[p.Name], null); 
      } 
      catch (Exception e) 
      { 
       Console.WriteLine(e.Message); 
      } 
     } 
     DataRow[] row = statusList.Select("SendingID = " + dr[0]); 
     foreach (DataRow r in row) 
     { 
      StatusHistory statusInstance = Activator.CreateInstance<StatusHistory>(); 
      var porpsh = statusInstance.GetType().GetProperties(BindingFlags.DeclaredOnly | BindingFlags.Public | BindingFlags.Instance); 
      foreach (var psh in porpsh) 
      { 
       try 
       { 
        psh.SetValue(statusInstance, r[psh.Name], null); 
       } 
       catch { } 
      } 
      sendingInstance.StatusHistory.Add(statusInstance); 
     } 
     list.Add(sendingInstance); 
    } 
    return list; 
}
