具體介紹C#程式取得IP位址的方法

這篇文章主要介紹了C程式設計取得IP地址的方法,結合實例形式分析了C#獲取客戶端IP地址的具體實現技巧,需要的朋友可以參考下

本文實例講述了C#編程獲取IP地址的方法。 ，具體如下：

1、取得客戶端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(&#39;,&#39;)[0];
    }
  }
  return clientIP;
}

2、伺服器端取得客戶端請求IP和客戶端機器名稱

/// <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);
}
