.NET获取客户端的操作系统、IP地址、浏览器版本

获取客户端的操作系统:

#region 获取操作系统版本号

/// <summary>
/// 获取操作系统版本号
/// </summary>
/// <returns></returns> public static string GetOSVersion()
{
  //UserAgent
  var userAgent = HttpContext.Current.Request.ServerVariables["HTTP_USER_AGENT"];   var osVersion = "未知";
  if (userAgent.Contains("NT 10.0"))
  {
    osVersion = "Windows 10";
  }
  else if (userAgent.Contains("NT 6.3"))
  {
    osVersion = "Windows 8.1";
  }
  else if (userAgent.Contains("NT 6.2"))
  {
    osVersion = "Windows 8";
  }   else if (userAgent.Contains("NT 6.1"))
  {
    osVersion = "Windows 7";
  }
  else if (userAgent.Contains("NT 6.0"))
  {
    osVersion = "Windows Vista/Server 2008";
  }
  else if (userAgent.Contains("NT 5.2"))
  {
    osVersion = "Windows Server 2003";
  }
  else if (userAgent.Contains("NT 5.1"))
  {
    osVersion = "Windows XP";
  }
  else if (userAgent.Contains("NT 5"))
  {
    osVersion = "Windows 2000";
  }
  else if (userAgent.Contains("NT 4"))
  {
    osVersion = "Windows NT4";
  }
  else if (userAgent.Contains("Me"))
  {
    osVersion = "Windows Me";
  }
  else if (userAgent.Contains(""))
  {
    osVersion = "Windows 98";
  }
  else if (userAgent.Contains(""))
  {
    osVersion = "Windows 95";
  }
  else if (userAgent.Contains("Mac"))
  {
    osVersion = "Mac";
  }
  else if (userAgent.Contains("Unix"))
  {
    osVersion = "UNIX";
  }
  else if (userAgent.Contains("Linux"))
  {
    osVersion = "Linux";
  }
  else if (userAgent.Contains("SunOS"))
  {
    osVersion = "SunOS";
  }
  return osVersion;
}
#endregion

获取客户端的IP地址:

#region 获取IP地址

/// <summary>
/// 获取IP地址
/// </summary>
/// <returns></returns> public static string GetIPAddress()
{
  string ipv4 = String.Empty;
  foreach (IPAddress IPA in Dns.GetHostAddresses(HttpContext.Current.Request.UserHostAddress))
  {
    if (IPA.AddressFamily.ToString() == "InterNetwork")
    {
      ipv4 = IPA.ToString();
      break;
    }
  }
  if (ipv4 != String.Empty)
  {
    return ipv4;
  }
  foreach (IPAddress IPA in Dns.GetHostAddresses(Dns.GetHostName()))
  {
    if (IPA.AddressFamily.ToString() == "InterNetwork")
    {
      ipv4 = IPA.ToString();
      break;
    }
  }
  return ipv4;
} #endregion

获取客户端的浏览器版本:

#region 获取浏览器版本号

/// <summary>
/// 获取浏览器版本号
/// </summary>
/// <returns></returns>
public static string GetBrowser()
{
  HttpBrowserCapabilities bc = HttpContext.Current.Request.Browser;
  return bc.Browser + bc.Version;
} #endregion
