'xmlns:xsi' 是重复的属性名称 [英] 'xmlns:xsi' is a duplicate attribute name
本文介绍了'xmlns:xsi' 是重复的属性名称的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我正在尝试编写一个 xml 编辑器，可以在其中加载、编辑特定的 xml 文件，然后保存以供进一步使用.所以xml文件的结构不能改变.
我正在尝试关注这个
它说我有一个重复的属性名称，而我正在从文件加载并且没有对该文件进行任何更改.
XML 文件结构:

解决方案
如果您在 Interlocking 类中注释掉 Xsi/Xsd 属性并向 Children 添加 XmlIgnore 属性，则它可以工作.xsi/xsd 命名空间甚至在输出中.

I am trying to follow this Stackoverflow question , but Save XML command is giving exception while writing back to the file. I am getting this error
which says i am having a duplicate attribute name, while i am loading from the file and changed nothing to that file.

}
if we send a "true" in this function, namespace issue is taken cared already in helper class. But @J.H solution is much better to use. Less string manipulation is always good.
解决方案
If you comment out the Xsi/Xsd properties in class Interlocking and add an XmlIgnore attribute to Children, it works. The xsi/xsd namespace is even in the output.
[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 }
};
}
}
}
Output:
