cutting-edge technologiesFuturistic programmers can be said to be the opposite of October programmers-today is the future, and any code written using yesterday's development tools is unparalleled in the eyes of futuristic programmers. Their goal is not a philosophy-to pursue the latest and most cutting-edge technologies.Don't be surprised if you see futuristic programmers blow your nose in front of you and boast that you have seen the latest JavaScript News on Hacker News recently, because they

Recently I made an RSS online aggregator, most of which are RSS2.0 encoded XML.. NET compilers can read the data correctly, but some of them are encoded in GBK format. NET cannot be read. if the XML encoding is manually changed to "gb2312" or other encoding, it cannot be read. However, if the encoding does not change, IE can be correctly viewed. What should I do next? it's really hard for me. How about changing the encoding? The RSS2.0 file to be read

Iaggregationfactory interface. You can overload methods in this interface to do 3 things:
Initialize your factory (in constructors)
Provides a set of aggregations provided by the factory (provided in a list, with actual instances of aggregated objects)
Returns a single instance of an aggregate object
Each instance of the aggregation needs to implement the Iaggrfunction interface. Many of the more meaningful methods, such as GetName, Getdatatype, and getparmaeterdefn, need to be implemented,
