我的问题是，我的程序没有从我的 XML 文件中获取数据并将其放入列表中

我可以很好地保存数据，但我无法将其加载回来。

这是我的保存功能

    public void Save_Data_Click(object sender, EventArgs e)
    {
        XmlSerializer PSR = new XmlSerializer(typeof(Pickup));
        XmlSerializer DSR = new XmlSerializer(typeof(Delivery));

        TextWriter PickupStream = new StreamWriter(@"Pickup Save Data.xml");
        TextWriter DeliveryStream = new StreamWriter(@"Delivery Save Data.xml");
        PSR.Serialize(PickupStream, thePickup);
        DSR.Serialize(DeliveryStream, theDelivery);
        DeliveryStream.Close();
        PickupStream.Close();

        MessageBox.Show("All data saved!");
    }

这是我的 xml 加载代码

  XmlSerializer SerializerObj = new XmlSerializer(typeof(Pickup));
  FileStream ReadFileStream = new FileStream(@"Pickup Save Data.xml", FileMode.Open, FileAccess.Read, FileShare.Read);
  Pickup LoadedObj = (Pickup)SerializerObj.Deserialize(ReadFileStream);
  ReadFileStream.Close();

这是我的接送班

 namespace Vans
 {
     [Serializable]
     public class Pickup
     {

    public List<Pickups> Pickups = new List<Pickups>();

    public void addPickup(Pickups Pic)
    {
        Pickups.Add(Pic);
    }

    public List<String> listPickups()
    {
        List<String> listPickups = new List<string>();
        foreach (Pickups pick in Pickups)
        {
            String pickupString = pick.ToString();
            listPickups.Add(pickupString);
        }

        return listPickups;

    }

    public Pickups getPickup(int i)
    {

        int c = 0;
        foreach (Pickups Pic in Pickups)
        {
            if (i == c)
                return Pic;
            c++;
        }
        return null;
    }
 }
}

我的 Delivery 类与 Pickup 类相同。

编辑

    <?xml version="1.0" encoding="utf-8"?>
    <Pickup xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"     xmlns:xsd="http://www.w3.org/2001/XMLSchema">
    <Pickups>
     <Pickups>
      <pickupfirstname>dsf</pickupfirstname>
      <pickuplastname>sdf</pickuplastname>
      <pickupdeliveryaddress>sd</pickupdeliveryaddress>
      <pickuptime>dsf</pickuptime>
    </Pickups>
  </Pickups>
</Pickup>

这是一些示例 XML 代码

在这个例子中，每个应该（反）序列化的字段都有一个注释[XmlElement]，也许这就是原因......

确保您的Pickups类如下以正确反序列化它：

public class Pickups
{
    public string pickupfirstname;
    public string pickuplastname;
    public string pickupdeliveryaddress;
    public string pickuptime;
}

注意：我已经在包含此类的情况下在本地测试了您的代码，并且运行良好。
