1：新建一个Net.cs类
/// <summary> /// 网络操作 /// </summary> public class Net { #region Ip(获取Ip) /// <summary> /// 获取Ip /// </summary> public static string Ip { get { var result = string.Empty; if (HttpContext.Current != null) result = GetWebClientIp(); if (string.IsNullOrEmpty(result)) result = GetLanIp(); return result; } } /// <summary> /// ===调用方法=== /// 直接调用此方法可获取IP /// </summary> public static string GetIP { get { string Ip = Net.Ip; string Location = Net.GetLocation(Net.Ip); return string.Format("IP:{0}; {1};", Ip, Location); } } /// <summary> /// 获取Web客户端的Ip /// </summary> private static string GetWebClientIp() { var ip = GetWebRemoteIp(); foreach (var hostAddress in Dns.GetHostAddresses(ip)) { if (hostAddress.AddressFamily == AddressFamily.InterNetwork) return hostAddress.ToString(); } return string.Empty; } /// <summary> /// 获取Web远程Ip /// </summary> private static string GetWebRemoteIp() { return HttpContext.Current.Request.ServerVariables["HTTP_X_FORWARDED_FOR"] ??

3：调用
在需要用到的地方直接调用此方法即可
var Ip=Net.GetIP;
