我正在序列化对象列表List<TestObject>
,并且XmlSerializer生成<ArrayOfTestObject>
属性,我想重命名或删除它
可以通过创建将List封装为字段的新类来完成吗?
[XmlRoot("Container")]
public class TestObject
{
public TestObject() { }
public string Str { get; set; }
}
List<TestObject> tmpList = new List<TestObject>();
TestObject TestObj = new TestObject();
TestObj.Str = "Test";
TestObject TestObj2 = new TestObject();
TestObj2.Str = "xcvxc";
tmpList.Add(TestObj);
tmpList.Add(TestObj2);
XmlWriterSettings settings = new XmlWriterSettings();
settings.OmitXmlDeclaration = true;
settings.Indent = true;
XmlSerializer serializer = new XmlSerializer(typeof(List<TestObject>));
using (XmlWriter writer = XmlWriter.Create(@"C:\test.xml", settings))
{
XmlSerializerNamespaces namespaces = new XmlSerializerNamespaces();
namespaces.Add(string.Empty, string.Empty);
serializer.Serialize(writer, tmpList, namespaces);
}
<ArrayOfTestObject>
<TestObject>
<Str>Test</Str>
</TestObject>
<TestObject>
<Str>xcvxc</Str>
</TestObject>
</ArrayOfTestObject>

最可靠的方法是声明最外层的DTO类:
[XmlRoot("myOuterElement")]
public class MyOuterMessage {
[XmlElement("item")]
public List<TestObject> Items {get;set;}
}
并序列化 (即将您的列表放入另一个对象)。
你可以避免包装类,但我不会:
class Program
{
static void Main()
{
XmlSerializer ser = new XmlSerializer(typeof(List<Foo>),
new XmlRootAttribute("Flibble"));
List<Foo> foos = new List<Foo> {
new Foo {Bar = "abc"},
new Foo {Bar = "def"}
};
ser.Serialize(Console.Out, foos);
}
}
public class Foo
{
public string Bar { get; set; }
}
问题,当您使用自定义属性时,您需要非常小心地存储和重新使用序列化程序,否则您将获得批次加载到内存中的动态程序集。如果您只使用XmlSerializer(Type)
构造函数,则可以避免这种情况,因为它会自动在内部缓存它。

更改以下行:
XmlSerializer serializer = new XmlSerializer(typeof(List<TestObject>));
要:
XmlRootAttribute root = new XmlRootAttribute("TestObjects");
XmlSerializer serializer = new XmlSerializer(typeof(List<TestObject>), root);
它应该有用。

您可以向XmlSerializer
构造函数添加一个附加参数,以从本质上命名根元素。
XmlSerializer xsSubmit = new XmlSerializer(typeof(List<DropDownOption>), new XmlRootAttribute("DropDownOptions"));
这将导致以下结构:
<DropDownOptions xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<DropDownOption>
<ID>1</ID>
<Description>foo</Description>
</DropDownOption>
<DropDownOption>
<ID>2</ID>
<Description>bar</Description>
</DropDownOption>
</DropDownOptions>

创建另一个类,如:
[XmlRoot("TestObjects")]
public class TestObjects: List<TestObject>
{
}
然后在密封时应用以下代码:
XmlSerializer serializer = new XmlSerializer(typeof(TestObjects));
MemoryStream memStream = new MemoryStream();
serializer.Serialize(memStream, tmpList);
