C# - XmlIgnore 不适用于 override 或 new 修饰符

Question

[TestFixture]
public class XmlIgnoreWithNewModifierTest
{
    public class Parent
    {
        public int Name { get; set; }
    }

    public class Child : Parent
    {
        [XmlIgnore]
        public new int Name
        {
            get { throw new NotImplementedException(); }
        }
    }

    [Test]
    public void Test()
    {
        var serializer = new XmlSerializer(typeof(Child));
        var stream = new MemoryStream();

        // Throws
        serializer.Serialize(stream, new Child());
    }
}

最后一行代码将抛出 InvalidOperationException 并带有内部 NotImplementedException。使 Parent.Name 虚拟和 Child.Name 覆盖没有帮助。

我想知道是否可以让 XmlIgnore 只对 Child.Name 起作用而不对 Parent.Name 起作用？

如本回答所述: Excluding some properties during serialization without changing the original class

你应该使用:

XmlAttributes attributes = new XmlAttributes { XmlIgnore = true };
XmlAttributeOverrides overrides = new XmlAttributeOverrides();
overrides.Add(typeof(Parent), "Name", attributes);

XmlSerializer serialize = new XmlSerializer(typeof(Child), overrides);
