调用方式:
#region 测试获取远程网页
GetPageCode gpc = new GetPageCode();
gpc.Url="http://ppcode.com/";
gpc.ProxyState=1;//使用代理服务器,0为不使用,设置为1后下面的代理设置才起作用
gpc.ProxyAddress="http://proxyName.com";//代理服务器地址
gpc.ProxyPort="80";//代理服务器的端口
gpc.ProxyAccount="proxy";//代理服务器账号
gpc.ProxyPassword="password";//代理服务器密码
gpc.ProxyDomain="bqc";//代理服务器域
gpc.OutFilePath=filePath;//设置输出文件路径的地方,如果不设置,则返回字符串
gpc.GetSource();//处理
string tempErr=gpc.NoteMessage;//如果出错,这里会提示
string tempCode=gpc.OutString;//返回的字符串
#endregion
