今天打算试着写个小聊天程序,但是要用到获取本机IP,以前从没用过。摆渡百度了一会儿,出于贪心,想把各种获取本机IP的方法给找出来。摆渡+测试了几个小时,于是有了下面的成果,有点小累,但看到这些成果,也很高兴。不一定很全,但也不少了。
①
[csharp] view plaincopy
- private void GetIP()
- {
- string hostName = Dns.GetHostName();//本机名
- //System.Net.IPAddress[] addressList = Dns.GetHostByName(hostName).AddressList;//会警告GetHostByName()已过期,我运行时且只返回了一个IPv4的地址
- System.Net.IPAddress[] addressList = Dns.GetHostAddresses(hostName);//会返回所有地址,包括IPv4和IPv6
- foreach (IPAddress ip in addressList)
- {
- listBox1.Items.Add(ip.ToString());
- }
- }
②使用IPHostEntry获取本机局域网地址
[csharp] view plaincopy
- static string GetLocalIp()
- {
- string hostname = Dns.GetHostName();//得到本机名
- //IPHostEntry localhost = Dns.GetHostByName(hostname);//方法已过期,只得到IPv4的地址
- <span style="WHITE-SPACE: pre"> </span> IPHostEntry localhost = Dns.GetHostEntry(hostname);
- IPAddress localaddr = localhost.AddressList[0];
- return localaddr.ToString();
- }
③获取本机网络ip地址
方法时通过向网站向一些提供IP查询的网站发送webrequest,然后分析返回的数据流
[csharp] view plaincopy
- string strUrl = "提供IP查询的网站的链接";
- Uri uri = new Uri(strUrl);
- WebRequest webreq = WebRequest.Create(uri);
- Stream s = webreq .GetResponse().GetResponseStream();
- StreamReader sr = new StreamReader(s, Encoding.Default);
- string all = sr.ReadToEnd();
- int i = all.IndexOf("[") + 1;
- //分析字符串得到IP
- return ip;
- /*
- 我用的是http://www.ip.cn/getip.php?action=getip&ip_url=&from=web
- (这种链接很容易找的,百度“IP”得到一些网站,分析一下网站的链接就能得到)
- 返回的数据是:
- <div class="well"><p>当前 IP:<code>0.0.0.0</code> 来自:XX省XX市 电信</p><p>GeoIP: Beijing, China</p></div>
- 解析这段就行
- */
④//由于用到了ManagementClass、ManagementObjectCollection;必须添加引用System.Management.dll及using System.Management;
[csharp] view plaincopy
- private void GetIP2()
- {
- string stringMAC = "";
- string stringIP = "";
- ManagementClass managementClass = new ManagementClass("Win32_NetworkAdapterConfiguration");
- ManagementObjectCollection managementObjectCollection = managementClass.GetInstances();
- foreach(ManagementObject managementObject in managementObjectCollection)
- {
- if ((bool)managementObject["IPEnabled"] == true)
- {
- stringMAC += managementObject["MACAddress"].ToString();
- string[] IPAddresses = (string[])managementObject["IPAddress"];
- if (IPAddresses.Length > 0)
- {
- stringIP = IPAddresses[0];
- }
- }
- }
- txtMAC.Text = stringMAC.ToString();
- txtIP.Text = stringIP.ToString();
- }
⑤调用一个网站提供的Web服务来查询IP网址:http://www.webxml.com.cn/zh_cn/web_services.aspx服务:http://webservice.webxml.com.cn/WebServices/IpAddressSearchWebService.asmx
弄了好半天,但是没学会怎样调用Web Service,按照搜到的页面做也不行,遂先放弃吧.....毕竟还未接触到WebService,改天把WebService搞定再来一定就容易了(留待以后完善吧)
⑥通过获取CMD里ipconfig命令的结果来得到IP
[csharp] view plaincopy
- private void GetIP6()
- {
- Process cmd = new Process();
- cmd.StartInfo.FileName = "ipconfig.exe";//设置程序名
- cmd.StartInfo.Arguments = "/all"; //参数
- //重定向标准输出
- cmd.StartInfo.RedirectStandardOutput = true;
- cmd.StartInfo.RedirectStandardInput = true;
- cmd.StartInfo.UseShellExecute = false;
- cmd.StartInfo.CreateNoWindow = true;//不显示窗口(控制台程序是黑屏)
- //cmd.StartInfo.WindowStyle = ProcessWindowStyle.Hidden;//暂时不明白什么意思
- /*
- 收集一下 有备无患
- 关于:ProcessWindowStyle.Hidden隐藏后如何再显示?
- hwndWin32Host = Win32Native.FindWindow(null, win32Exinfo.windowsName);
- Win32Native.ShowWindow(hwndWin32Host, 1); //先FindWindow找到窗口后再ShowWindow
- */
- cmd.Start();
- string info = cmd.StandardOutput.ReadToEnd();
- cmd.WaitForExit();
- cmd.Close();
- textBox1.AppendText(info);
- }
⑦NetworkInformation
[csharp] view plaincopy
- private void GetIP5()
- {
- //需要的命名空间
- //using System.Net.NetworkInformation;
- //using System.Net.Sockets;
- string str = "";
- NetworkInterface[] adapters = NetworkInterface.GetAllNetworkInterfaces();
- int i = 0;
- foreach (NetworkInterface adapter in adapters)
- {
- IPInterfaceProperties adapterProperties = adapter.GetIPProperties();
- UnicastIPAddressInformationCollection allAddress =
- adapterProperties.UnicastAddresses;
- if (allAddress.Count > 0)
- {
- str += "interface " + i + "description:\n\t " + adapter.Description + "\n ";
- i++;
- foreach (UnicastIPAddressInformation addr in allAddress)
- {
- if (addr.Address.AddressFamily == AddressFamily.InterNetworkV6)
- {
- ipListComb.Items.Add(addr.Address);
- }
- if (addr.Address.AddressFamily == AddressFamily.InterNetwork)
- {
- comboBox1.Items.Add(addr.Address);
- }
- }
- }
- }
- MessageBox.Show(str);
- }
