C#编程获取IP地址的方法示例

本文实例讲述了C#编程获取IP地址的方法。分享给大家供大家参考，具体如下：

1、获取客户端IP

/// <summary>
/// 获取客户端Ip
/// </summary>
/// <returns></returns>
public String GetClientIp()
{
 String clientIP = "";
 if (System.Web.HttpContext.Current != null)
 {
   clientIP = System.Web.HttpContext.Current.Request.ServerVariables["HTTP_X_FORWARDED_FOR"];
   if (string.IsNullOrEmpty(clientIP) || (clientIP.ToLower() == "unknown"))
   {
     clientIP = System.Web.HttpContext.Current.Request.ServerVariables["HTTP_X_REAL_IP"];
     if (string.IsNullOrEmpty(clientIP))
     {
       clientIP = System.Web.HttpContext.Current.Request.ServerVariables["REMOTE_ADDR"];
     }
   }
   else
   {
     clientIP = clientIP.Split(',')[0];
   }
 }
 return clientIP;
}

2、服务器端获取客户端请求IP和客户端机器名称

/// <summary>
/// 服务器端获取客户端请求IP和客户端机器名称
/// </summary>
public static void GetClientInfo()
{
 OperationContext context = OperationContext.Current;
 MessageProperties messageProperties = context.IncomingMessageProperties;
 RemoteEndpointMessageProperty endpointProperty = messageProperties[RemoteEndpointMessageProperty.Name] as RemoteEndpointMessageProperty;
 HttpRequestMessageProperty requestProperty = messageProperties[HttpRequestMessageProperty.Name] as HttpRequestMessageProperty;
 string clientIp = !string.IsNullOrEmpty(requestProperty.Headers["X-Real-IP"]) ? requestProperty.Headers["X-Real-IP"] : endpointProperty.Address;
 string clientName = Environment.MachineName;
 Console.WriteLine("ClientIp: " + clientIp + "clientName:" + clientName);
}
