'xmlns：xsi'是重复的属性名称

Question

我正在尝试编写一个xml编辑器，其中可以加载，编辑特定的xml文件，然后保存以供进一步使用。所以不能改变xml文件的结构。

我正在尝试遵循此Stackoverflow question，但保存XML命令在写回文件时给出了异常。我收到此错误

表示我有一个重复的属性名称，而我从文件加载并且没有对该文件进行任何更改。

XML文件结构：

如果我们在此函数中发送“true”，则在辅助类中已经考虑了名称空间问题。但是@ J.H解决方案要好得多。减少字符串操作总是很好。

Answer 1

如果在类Interlocking中注释掉Xsi / Xsd属性并向Children添加XmlIgnore属性，则它可以正常工作。 xsi / xsd命名空间甚至在输出中。

[XmlRoot(ElementName = "interlocking")]
public class Interlocking
{
    [XmlElement(ElementName = "signals")]
    public List<Signals> Signals { get; set; }
    [XmlElement(ElementName = "routes")]
    public List<Routes> Routes { get; set; }

    //[XmlAttribute(AttributeName = "xsi", Namespace = "http://www.w3.org/2000/xmlns/")]
    //public string Xsi { get; set; }
    //[XmlAttribute(AttributeName = "xsd", Namespace = "http://www.w3.org/2000/xmlns/")]
    //public string Xsd { get; set; }

    [XmlIgnore]
    public IList Children
    {
        get
        {
            return new CompositeCollection()
            {
                new CollectionContainer() { Collection = Signals },
                new CollectionContainer() { Collection = Routes }
            };
        }
    }
}

输出：
