protected void Page_Load(object sender, EventArgs e)
{
WebInfo info = new WebInfo();
string infoOut = string.Format("站点：{0}<br>域名：{1}",info.WebName,info.WebUrl);
Response.Write(infoOut);
}

public class WebInfo
{

public WebInfo():this("搜索吧","http://www.sosuo8.com/")
{
}

public WebInfo(string webUrl):this("搜索吧",webUrl)
{
}

public WebInfo(string webName, string webUrl)
{
_webName = webName;
_webUrl = webUrl;
}

private string _webName;
private string _webUrl;
