{
IPAddress localIp = null;
try
{
IPAddress[] ipArray;
ipArray = Dns.GetHostAddresses(Dns.GetHostName());
localIp = ipArray.First(ip => ip.AddressFamily == AddressFamily.InterNetwork);
}
catch (Exception ex)
{
MessageBox.Show(ex.StackTrace + "\r\n" + ex.Message, "错误", MessageBoxButtons.OKCancel, MessageBoxIcon.Error);
Log.WriteLog(ex);
}
if (localIp == null)
{
localIp = IPAddress.Parse("127.0.0.1");
}
return localIp.ToString();
}
ipArray = Dns.GetHostAddresses(Dns.GetHostName());会返回一个IP数组,里面会有多个IP地址
localIp = ipArray.First(ip => ip.AddressFamily == AddressFamily.InterNetwork);会返回符合IP格式的第一个数据,想获取多个可以往后获取。
