XmlElement is XmlNode, not interchangeable.

XmlNode error may occur because the XmlNode that contains more than XmlElement XmlElement change.


the XmlNode change XmlElement is possible, but if the

we can find, XmlElement inherits from the XmlNode, the inheritance point of view:

XmlElement

commonly used in the code:
C # XmlElement and XmlNode accurate interpretation of the difference between
d = “1″> 1

on this both the difference between the online version, said are very detached, and some are very professional, but the theory is not enough essence. Most of them are:
Therefore, the derived class with more derived class members.

Note : derived class access to the members of the base class
s

=
string

derived class can access public members of the base class, protected members, internal members and protected internal members. Even if the derived class inherits the private member of the base class, and still not have access to these members. However, all these private members in a derived class still exists, and perform the same work in the base class itself. For example, suppose a protected base class method to access the private field. Make the inherited base class method to work properly, the derived class must have the field.

Is XmlNode multiple nodes collectively referred to Shopping. But the XmlElement specifically refers to the element node.
C #
4 to XmlElement have many methods of operation on the Attribute easy its properties to read and write operations (XmlNode can also be obtained through the Attributes property of the list of attributes).
element node corresponding conversion XmlElement, so that both can use the XmlNode function of its unique method of operation of the attributes can also be used.
1, through inheritance relationship XmlElement inherits from XmlLinkedNode inherited from XmlNode class, can be seen XmlElement is XmlNode subclass. We know that the subclass inherits all the properties and methods of the parent class methods and properties owned by the XmlNode, XmlElement class is used.
online to see someone so comment on the difference between these two classes: the XmlNode that contains the child node, XmlElement that contains only attributes in and of itself does not contain child nodes. I passed the code test and found that even XmlElement, but also can the ChildNodes to obtain the list of child nodes. Although the breakpoint mode, I did not find XmlElement ChildNodes property. The following are examples:
/ / just The XmlNode
use xml recorded background music information of a website, to understand a bit. Net operating an XML document. See a little good:
/ / both XmlNode is XmlElement
/ / XmlNode is also XmlElement but only img and aspnet.jpg The XmlNode
3 XmlElement with the current class can be instantiated directly , and XmlNode is an abstract class, must pass the XmlDocument instance through CreateNode created.
