XML 序列化和反序列化 c# 中的列表<字符串>

我有一个跟随类的对象

[XmlRoot("http://schemas.abc.com")]
[DataContract]
public class Employee
{
    [XmlAttribute]
    [DataMember]
    public List<string> Positions { get; set; }
}

职位包含以下两个字符串"项目经理"和"高级项目经理"

我通过以下方法序列化了这个对象并保存在数据库中

public static string Serialize(Employee entity)
 {
    var memoryStream = new MemoryStream();
    var serializer = new XmlSerializer(typeof(Employee));
    using (var xmlTextWriter = new XmlTextWriter(memoryStream,
    Encoding.Unicode))
    {
         serializer.Serialize(xmlTextWriter, entity);
         xmlTextWriter.Close();
    }
    return UnicodeByteArrayToString(memoryStream.ToArray());
}
private static string UnicodeByteArrayToString(byte[] input)
{
   var constructedString = Encoding.Unicode.GetString(input);
   return constructedString;
}

然后我通过以下方法检索和反序列化对象

 public static Employee Deserialize(string str)
    {
        var data = StringToUnicodeByteArray(str);
        var memoryStream = new MemoryStream(data);
        var serializer = new XmlSerializer(typeof(Employee));
        var xmlTextReader = new XmlTextReader(memoryStream);
        return (Employee)serializer.Deserialize(xmlTextReader);
    }
 private static byte[] StringToUnicodeByteArray(string input)
 {
   var byteArray = Encoding.Unicode.GetBytes(input);
   return byteArray;
 }

现在我在位置列表中获得了 5 个字符串对象

"项目"、"

经理"、"高级"、"项目"、"经理"反序列化是在每个空格后创建新的字符串对象

快速帮助将不胜感激
