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
- private void GetIP()
- {
- string hostName = Dns.GetHostName();
-
- System.Net.IPAddress[] addressList = Dns.GetHostAddresses(hostName);
- foreach (IPAddress ip in addressList)
- {
- listBox1.Items.Add(ip.ToString());
- }
- }
②使用IPHostEntry获取本机局域网地址
- static string GetLocalIp()
- {
- string hostname = Dns.GetHostName();
-
- <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
- 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;
-
- return ip;
-
④//由于用到了ManagementClass、ManagementObjectCollection；必须添加引用System.Management.dll及using System.Management;
- 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
- private void GetIP6()
- {
- Process cmd = new Process();
- cmd.StartInfo.FileName = "ipconfig.exe";
- cmd.StartInfo.Arguments = "/all";
- cmd.StartInfo.RedirectStandardOutput = true;
- cmd.StartInfo.RedirectStandardInput = true;
- cmd.StartInfo.UseShellExecute = false;
- cmd.StartInfo.CreateNoWindow = true;
-
- cmd.Start();
- string info = cmd.StandardOutput.ReadToEnd();
- cmd.WaitForExit();
- cmd.Close();
- textBox1.AppendText(info);
- }
⑦NetworkInformation
- private void GetIP5()
- {
-
-
-
- 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);
- }
