阅读更多关于 XmlReader/XmlWriter 类

　　XmlReader用于读取Xml文件，XmlWriter用于将数据写到Xml文件。其实，在印象当中，XML很多的操作类都支持直接Save、Read也支持接受XmlReader与XmlWriter类的示例作为参数，但是为什么还要有这个两类来专门用于读写XML文件呢？因为它们有强大的自定义格式功能；一、XmlReader的使用　　XmlReader类专门用于读取Xml文件，最大的特点在于支持 Settings。属性说明 AttributeCount 当在派生类中被重写时，获取当前节点上的属性数 BaseURI 当在派生类中被重写时，获取当前节点的基 URI CanReadBinaryContent 获取一个值，该值指示 XmlReader 是否实现二进制内容读取方法 Depth 获取 XML 文档中当前节点的深度 EOF 获取一个值，该值指示此读取器是否定位在流的结尾 HasAttributes 获取一个值，该值指示当前节点是否有任何属性 HasValue 获取一个值，该值指示当前节点是否可以具有 Value IsDefault 获取一个值，该值指示当前节点是否是从 DTD 或架构中定义的默认值生成的特性 IsEmptyElement 获取一个值，该值指示当前节点是否为空元素（例如 <MyElement/>） Item 获取具有指定索引的属性的值，支持整形，字符串

So far it is almost working, except for one thing: It is not copying the attributes. Can anyone tell me why this is happening? Here is a sample of what it is supposed to copy/modify

问题 I am creating an ASHX that returns XML however it expects a path when I do XmlWriter writer = XmlWriter.Create(returnXML, settings) But returnXML is just an empty string right now (guess that won't work), however I need to write the XML to something that I can then send as the response text. I tried XmlDocument but it gave me an error expecting a string.

问题 I am implementing a custom xmlwriter and I want to omit any elements with a particular name, like <ABC> . How do I actually do that?

How do I tell WriteEndElement method to skip writing

问题 I am not very well versed with .NET's XML libraries and trying to wrap my head around IXmlSerializable interface. I am developing a windows store app (W8) and wish to use the IXmlSerializable interface, however am running into issues.
