In app. config and web. config, we usually use custom nodes to complete the configuration content to be extended. In the past, we had to inherit the configurationsection, configurationelementcollection, and configurationelement classes to read configuration information.CodeComplex. Later, we can easily query the configuration information through the LINQ to XML file, but this reduces the definition of the class. We can only read or fill in the class we define through xmlnode.

Android is the foreshadowing that Google has been burying in the mobile market many years ago, and it is not Google's emerging iOS dog.2 Misunderstanding II: Androbi WP and other fees and charges syst

As described in the JDK documentation, the Invocationhandler interface handles a method invocation with the help of a proxy instance (proxy instance). Now we k
