Obtaining client IP address in WCF 3.0

Question

Apparently you can easily obtain a client IP address in WCF 3.5 but not in WCF 3.0. Anyone know how?

Answer 1

Simply put you can't.

Answer 2

This doesn't help you in 3.0, but I can just see people finding this question and being frustrated because they are trying to get the client IP address in 3.5. So, here's some code which should work:

using System.ServiceModel;
using System.ServiceModel.Channels;

OperationContext context = OperationContext.Current;
MessageProperties prop = context.IncomingMessageProperties;
RemoteEndpointMessageProperty endpoint =
    prop[RemoteEndpointMessageProperty.Name] as RemoteEndpointMessageProperty;
string ip = endpoint.Address;

Answer 3

It turns out you can, so long as (a) your service is being hosted in a Web Service (obviously) and (b) you enable AspNetCompatibility mode, as follows:

    <system.serviceModel>
         !-- this enables WCF services to access ASP.Net http context -->
         <serviceHostingEnvironment aspNetCompatibilityEnabled="true"/>
...
    </system.serviceModel>

Answer 4

You can if you are targeting .NET 3.0 SP1.

OperationContext context = OperationContext.Current;
MessageProperties prop = context.IncomingMessageProperties;
RemoteEndpointMessageProperty endpoint = prop[RemoteEndpointMessageProperty.Name] as RemoteEndpointMessageProperty;
string ip = endpoint.Address;
