如何取得本机在局域网内的IP 我的电脑在局域网内的IP是192.168.0.90请问C#如何能取得这个IP地址呢??? 解决方案 » 免费领取超大流量手机卡,每月29元包185G流量+100分钟通话, 中国电信官方发货 可以1、你访问web,web可以request到2、c#程序本地运行,调用句柄,也可以public class getIP { [DllImport("Iphlpapi.dll")] private static extern int SendARP(Int32 dest, Int32 host, ref Int64 mac, ref Int32 length); [DllImport("Ws2_32.dll")] private static extern Int32 inet_addr(string ip); //获取本机的IP public string getLocalIP() { string strHostName = Dns.GetHostName(); //得到本机的主机名 IPHostEntry ipEntry = Dns.GetHostByName(strHostName); //取得本机IP string strAddr = ipEntry.AddressList[0].ToString(); return (strAddr); } //获取本机的MAC public string getLocalMac() { string mac = null; ManagementObjectSearcher query = new ManagementObjectSearcher("SELECT * FROM Win32_NetworkAdapterConfiguration"); ManagementObjectCollection queryCollection = query.Get(); foreach (ManagementObject mo in queryCollection) { if (mo["IPEnabled"].ToString() == "True") mac = mo["MacAddress"].ToString(); } return (mac); } //获取远程主机IP public string[] getRemoteIP(string RemoteHostName) { IPHostEntry ipEntry = Dns.GetHostByName(RemoteHostName); IPAddress[] IpAddr = ipEntry.AddressList; string[] strAddr = new string[IpAddr.Length]; for (int i = 0; i < IpAddr.Length; i++) { strAddr[i] = IpAddr[i].ToString(); } return (strAddr); } //获取远程主机MAC public string getRemoteMac(string localIP, string remoteIP) { Int32 ldest = inet_addr(remoteIP); //目的ip Int32 lhost = inet_addr(localIP); //本地ip try { Int64 macinfo = new Int64(); Int32 len = 6; int res = SendARP(ldest, 0, ref macinfo, ref len); return Convert.ToString(macinfo, 16); } catch (Exception err) { Console.WriteLine("Error:{0}", err.Message); } return 0.ToString(); } } 楼上的这个方法可以public string getLocalIP(){ string strHostName = Dns.GetHostName(); //得到本机的主机名 IPHostEntry ipEntry = Dns.GetHostByName(strHostName); //取得本机IP string strAddr = ipEntry.AddressList[0].ToString(); return (strAddr);}但要注意的是,当你的机器存在多个网卡/连接方式时,就需要再具体判断一下了,因为这个时候AddressList会有多个项,即使只有单网卡,其中还是会包含IPv6的IP(开启了IPv6后) Dns.GetHostName(); IPHostEntry ipEntry = Dns.GetHostByName(strHostName); vs2008 自定义快捷键不能用 接口和类一样么?

1、你访问web,web可以request到
2、c#程序本地运行,调用句柄,也可以
public class getIP
{
[DllImport("Iphlpapi.dll")]
private static extern int SendARP(Int32 dest, Int32 host, ref Int64 mac, ref Int32 length);
[DllImport("Ws2_32.dll")]
private static extern Int32 inet_addr(string ip); //获取本机的IP
public string getLocalIP()
{
string strHostName = Dns.GetHostName(); //得到本机的主机名
IPHostEntry ipEntry = Dns.GetHostByName(strHostName); //取得本机IP
string strAddr = ipEntry.AddressList[0].ToString();
return (strAddr);
}
//获取本机的MAC
public string getLocalMac()
{
string mac = null;
ManagementObjectSearcher query = new ManagementObjectSearcher("SELECT * FROM Win32_NetworkAdapterConfiguration");
ManagementObjectCollection queryCollection = query.Get();
foreach (ManagementObject mo in queryCollection)
{
if (mo["IPEnabled"].ToString() == "True")
mac = mo["MacAddress"].ToString();
}
return (mac);
} //获取远程主机IP
public string[] getRemoteIP(string RemoteHostName)
{
IPHostEntry ipEntry = Dns.GetHostByName(RemoteHostName);
IPAddress[] IpAddr = ipEntry.AddressList;
string[] strAddr = new string[IpAddr.Length];
for (int i = 0; i < IpAddr.Length; i++)
{
strAddr[i] = IpAddr[i].ToString();
}
return (strAddr);
}
//获取远程主机MAC
public string getRemoteMac(string localIP, string remoteIP)
{
Int32 ldest = inet_addr(remoteIP); //目的ip
Int32 lhost = inet_addr(localIP); //本地ip try
{
Int64 macinfo = new Int64();
Int32 len = 6;
int res = SendARP(ldest, 0, ref macinfo, ref len);
return Convert.ToString(macinfo, 16);
}
catch (Exception err)
{
Console.WriteLine("Error:{0}", err.Message);
}
return 0.ToString();
}
}
public string getLocalIP()
{
string strHostName = Dns.GetHostName(); //得到本机的主机名
IPHostEntry ipEntry = Dns.GetHostByName(strHostName); //取得本机IP
string strAddr = ipEntry.AddressList[0].ToString();
return (strAddr);
}
但要注意的是,当你的机器存在多个网卡/连接方式时,就需要再具体判断一下了,
因为这个时候AddressList会有多个项,即使只有单网卡,其中还是会包含IPv6的IP(开启了IPv6后)
IPHostEntry ipEntry = Dns.GetHostByName(strHostName);
