获取本地ip

string localIp = string.Empty;
    string hostName = Dns.GetHostName();
    
    //使用Dns获取ip地址可能会有多个
    Console.WriteLine("--------DNS获取--------");
    IPAddress[] addres = Dns.GetHostAddresses(hostName);
    foreach (var item in addres)
    {
    	Console.WriteLine(item.ToString());
    }
    
    IPAddress[] addressList = Dns.GetHostEntry(hostName).AddressList;
    foreach (IPAddress ipAddress in addressList)
    {
    	if (ipAddress.AddressFamily == AddressFamily.InterNetwork)
    	{
    		localIp = ipAddress.ToString();
    	}
    }
    
    Ping p1 = new Ping();
    PingReply reply = p1.Send(localIp); //发送主机名或Ip地址
    if (reply.Status == IPStatus.Success)
    {
    	Console.WriteLine(string.Format("Address: {0} ", reply.Address.ToString()));
    }
    
    Console.WriteLine("本地ip:{0}", localIp);

//转换编码
     Encoding gb = System.Text.Encoding.GetEncoding("utf-8");
     //获取字节数组
     byte[] bytes = gb.GetBytes(html);
     totalLength += bytes.Length;

//判断一个字符串只包含数字或者字母
    string uid = "58682b66c46bc7bd49f84b427fb71932";
    System.Text.RegularExpressions.Regex.IsMatch(uid, @"^[a-zA-Z0-9]*$")
    
    string src = "http://www.baidu.com";
    string reSrc = src.Substring(src.IndexOf("http:", StringComparison.Ordinal), src.IndexOf("png", StringComparison.Ordinal) + 3);
    
    //常用转化url方法
    Uri uri = new Uri(new Uri(httpsItem.Url), node.Attributes["href"].Value);
    
    //Json列表形式情况的转化
    JArray ja = JArray.Parse(html);
