Demo Program Structure

To create a demo program, I chose the new C#windows form application named Imgspider in Visual Studio 2013, and the Add Controls folder contains the encapsulated Label,textbox control The base class used by the dictionary entity in the core folder The Entity folder has a mapping class that reads the configuration file Dict.xml, the helper folder has downloadhelper for downloading the picture, Htmlparserhelper parsing html,xmlhelper reading the XML document, and the form file Frmautoborwser is the process The operating interface of the sequence. Figure 2 shows the overall structure of the demo program.

Program execution form File Frmautoborwser
