本文实例讲述了C#编程获取IP地址的方法。，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);
}
希望本文所述对大家C#程序设计有所帮助。
