Introduction: When doing wireless projects, some part of the communication company's data communication is interactive through XML, so we must dynamically capture data on the fixed Internet provided by the communication company, and study how to capture the fixed URL. Data, now share with you. Class name getPageCode, there is a method getSource, pass the attribute delivery parameters, the parameters are controlled to get the address of the URL, the proxy server settings and output methods, where everyone can expand their own needs, I only provide two The way, one is to write directly to a local file, and the other is to return a string. In the class, I have made more detailed notes. I think everyone is easy to understand. If I don't understand, I will ask MSN: Yubo@x263.net.
Calling method: #Region test Get remote page getPagecode GPC = new getPagecode (); gpc.url = "http://ppcode.com"; gpc.proxyState = 1; // Using proxy server, 0 is not used, set to 1 The proxy settings below act actively gpc.proxyaddress = "http://proxyname.com"; // proxy server address gpc.proxyport = "80"; // proxy server port gpc.proxyaccount = "proxy"; // Proxy server account gpc.proxypassword = "password"; // proxy server password gpc.proxyDomain = "bqc"; // proxy server domain gpc.outfilePath = filepath; // Setting the output file path, if not set, Return string gpc.getsource (); // Handling string temperr = gpc.noteMessage; // If an error, here will prompt string tempcode = gpc.outString; // Returns #ENDREGION Class code: use system; using System.collections; using system.data; using system.drawing; using system.io; using system.net; using system.text; using system.Web;
