Question

public class PersistableObject
    {
        public static T Load<T>(string fileName) where T : PersistableObject, new()
        {
            T result = default(T);

            using (XmlReader reader = XmlReader.Create(fileName))
            {
                result = new XmlSerializer(typeof(T)).Deserialize(reader) as T;
            }

            return result;
        }

        public void Save<T>(string fileName) where T : PersistableObject
        {
            using (FileStream stream = new FileStream(fileName, FileMode.CreateNew))
            {
                new XmlSerializer(typeof(T)).Serialize(stream, this);
            }
        }
    }

public class DatabaseConfiguration : PersistableObject
{
    public string Host { get; set; }
    public string Schema { get; set; }
    public string Username { get; set; }
    public string Password { get; set; }
}

我使用以下代码加载XML：

var configuration = PersistableObject.Load<DatabaseConfiguration>("Database.xml");

但是，配置的属性为null。这是Database.xml：

<?xml version="1.0"?>
<DatabaseConfiguration xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" />
  <Host>localhost</Host>
  <Schema>chromium</Schema>
  <Username>root</Username>
  <Password></Password>
</DatabaseConfiguration>

由于某种原因，它们保持为空，并且未分配任何内容。为什么？

Answer 1

您的Database.xml内容不正确，特别是关闭DatabaseConfiguration元素的第二行。

将其替换为：

<?xml version="1.0"?>
<DatabaseConfiguration xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" >
  <Host>localhost</Host>
  <Schema>chromium</Schema>
  <Username>root</Username>
  <Password></Password>
</DatabaseConfiguration>

XML反序列化不起作用
