使用XmlSerializer進行反序列化時出錯

Question

我使用此代碼收到異常;
InnerException: System.InvalidOperationException
Message=The specified type was not recognized: name='Person',
namespace='', at "<"Contact xmlns=''>. 以下是我認爲的相關代碼。
Person類是沒有任何註解的裸類，並且不從任何接口繼承。
如何使反序列化識別我的類？ 在此先感謝。

public class Contacts : List<Contact.Contact> 
{ 
    private void PopulateTypeList() 
    { 
     types.Add(typeof(Contact.Contact)); 
     types.Add(typeof(Contact.Company)); 
     types.Add(typeof(Contact.Person)); 
     types.Add(typeof(ContactData.Direction)); 
     types.Add(typeof(ContactData.email)); 
     types.Add(typeof(ContactData.Phone)); 
    } 

    public void Load() 
    { 
     try 
     { 
      using (System.Xml.XmlReader stream = System.Xml.XmlReader.Create(fileName)) 
      { 
       XmlSerializer xs = new XmlSerializer(typeof(List<Contact.Contact>)); 
       // this roundabout way is for making it possible for this class to 
       // inherit from List<Contact.Contact> and still use a method that 
       // gives the stored data as an value in the object 
here is error List<Contact.Contact> data = 
        (List<Contact.Contact>)xs.Deserialize(stream); 
       this.Clear(); 
       this.AddRange(data); 
      } 
     } 
     catch (System.IO.FileNotFoundException) 
     { 
      // do nothing; no file, new database 
     } 
    } 

    public void Save() 
    { 
     using (System.Xml.XmlWriter stream = System.Xml.XmlWriter.Create(fileName)) 
     { 
      XmlSerializer xs = 
       new XmlSerializer(typeof(List<Contact.Contact>), types.ToArray()); 
      List<Contact.Contact> data = this.ToList(); 
      xs.Serialize(stream, data); 
     } 
    }

嘗試通過類型列表中給您deserialisation創建串行器：

XmlSerializer xs = new XmlSerialiser(typeof(List<Contact.Contact>), types.ToArray());
