如何设置ClientCredentials？

Question

我正在尝试使用WCF服务：

服务的配置是：

<?xml version="1.0" encoding="utf-8"?>
<configuration>
    <system.serviceModel>
        <bindings>
            <netNamedPipeBinding>

                    <reliableSession ordered="true" inactivityTimeout="00:10:00"

                </binding>
            </wsHttpBinding>
        </bindings>
        <client>
            <endpoint address="net.tcp://webapppro-v11/FlightInfoWebService/FlightInfoService.svc"
                binding="netTcpBinding" bindingConfiguration="netTcpEndpoint"
                contract="FlightInfoService" name="netTcpEndpoint" />
            <endpoint address="net.pipe://webapppro-v11/FlightInfoWebService/FlightInfoService.svc"
                binding="netNamedPipeBinding" bindingConfiguration="netNamedPipeEndpoint"

            <endpoint address="http://webapppro-v11/FlightInfoWebService/FlightInfoService.svc"
                binding="wsHttpBinding" bindingConfiguration="wsHttpBindingConfiguration"
                contract="FlightInfoService" name="wsHttpBindingConfiguration" />
        </client>
    </system.serviceModel>
</configuration>

当我尝试拨打该服务时：

public async void LoadCities()
{
    _client = new FlightInfoServiceClient(Maquette_MyAirport_Win8.FlightService.FlightInfoServiceClient.EndpointConfiguration.wsHttpBindingConfiguration, "http://servuucs.fr/FlightInfoWebService/FlightInfoService.svc");

    var citiesResponse = await _client.GetAllCitiesAsync(new BaseRequest());
    var  myCities = citiesResponse.Cities;
}

我抓住了这个例外：

  

错误：UnAuthorizedAccess说明：您无权访问此服务
