My Asp.net 2.0 rsss display

I have been learning. Net for a while and have made some small things. It seems naive now. I haven't stayed up for a long time, and I'm not used to it. This evening, we are engaged in the XML data display of RSS. I also hope to communicate with you. You can customize the XML document address to be displayed and the number of records displayed.
