我试图反序列化这个xml结构.
<?xml version="1.0"?>
<DietPlan>
<Health>
<Fruit>Test</Fruit>
<Fruit>Test</Fruit>
<Veggie>Test</Veggie>
<Veggie>Test</Veggie>
</Health>
</DietPlan>
我试过：
[Serializable]
[XmlRoot(ElementName = "DietPlan")]
public class TestSerialization
{
[XmlArray("Health")]
[XmlArrayItem("Fruit")]
public string[] Fruits { get; set; }
[XmlArray("Health")]
[XmlArrayItem("Veggie")]
public string[] Veggie { get; set; }
}
但是这会抛出一个异常“XML元素已经存在于当前作用域中,使用XML属性为该元素指定另一个XML名称或命名空间.
感谢adv.
解决方法
您需要一个通用类型才能反序列化您的XML,并且您可以使用[XmlElement]命名空间定义根据元素名称实例化的类型,如下所示.
public class StackOverflow_15907357
{
const string XML = @"<?xml version=""1.0""?>
<DietPlan>
<Health>
<Fruit>Test</Fruit>
<Fruit>Test</Fruit>
<Veggie>Test</Veggie>
<Veggie>Test</Veggie>
</Health>
</DietPlan>";
[XmlRoot(ElementName = "DietPlan")]
public class TestSerialization
{
[XmlArray("Health")]
[XmlArrayItem("Fruit",Type = typeof(Fruit))]
[XmlArrayItem("Veggie",Type = typeof(Veggie))]
public Food[] Foods { get; set; }
}
[XmlInclude(typeof(Fruit))]
[XmlInclude(typeof(Veggie))]
public class Food
{
[XmlText]
public string Text { get; set; }
}
public class Fruit : Food { }
public class Veggie : Food { }
public static void Test()
{
MemoryStream ms = new MemoryStream(Encoding.UTF8.GetBytes(XML));
XmlSerializer xs = new XmlSerializer(typeof(TestSerialization));
TestSerialization obj = (TestSerialization)xs.Deserialize(ms);
foreach (var food in obj.Foods)
{
Console.WriteLine("{0}: {1}",food.GetType().Name,food.Text);
}
}
}
