在C#中获取用户的IP地址主要有两种方法:
string userIP = HttpContext.Current.Request.UserHostAddress;
OperationContext context = OperationContext.Current;
MessageProperties messageProperties = context.IncomingMessageProperties;
RemoteEndpointMessageProperty endpointProperty = messageProperties[RemoteEndpointMessageProperty.Name] as RemoteEndpointMessageProperty;
string userIP = endpointProperty.Address;
这些方法可以用来获取当前用户的IP地址,以便进行相关的操作。
