I need to connect to some public wcf service, but there is some proxy between me and service. If i use default proxy settings such as
<system.net>
<defaultProxy useDefaultCredentials="true" />
</system.net>
or
HttpWebRequest.DefaultWebProxy
it works perfectly fine but i don't need to set proxy settings for entire application, i need to set it for specific connection. So how I can do that?
I saw ProxyAddress property
(client.Endpoint.Binding as BasicHttpBinding).ProxyAddress
but there is no any properties for credentials... I was thinking to somehow modify HttpWebRequest, but I do not know how to get it...
Solved
Thank you all for your answers.
Answer of AntonK suitable for solving my problem.
At the time when this question was actual, I solved it in the same way, but without the use of web.config and wrote this method
void SetProxySettings<TChannel>(ClientBase<TChannel> client,
bool useProxy, string address, int port, string login, string password)
where TChannel : class
{
if (!useProxy) return;
var b = client.Endpoint.Binding as BasicHttpBinding;
if (b == null)
{
System.Diagnostics.Debug.WriteLine("Binding of this endpoint is not BasicHttpBinding");
return;
}
b.ProxyAddress = new Uri(string.Format("http://{0}:{1}", address, port));
b.UseDefaultWebProxy = false; // !!!
b.Security.Mode = BasicHttpSecurityMode.Transport;
b.Security.Transport.ClientCredentialType = HttpClientCredentialType.None; // !!!
b.Security.Transport.ProxyCredentialType = HttpProxyCredentialType.Basic; // !!!
if (client.ClientCredentials == null) return;
client.ClientCredentials.UserName.UserName = login;
client.ClientCredentials.UserName.Password = password;
}
Here's an article dealing with this issue.

In summary, this is how to set a proxy for a specific service in the web.config. In the binding config, set proxyAddress="http://myproxy:8080" and set useDefaultWebProxy="false"
<bindings>
<basicHttpBinding>
<binding name="SubscriberFulfilmentServiceSOAP12Binding" closeTimeout="00:01:00"
openTimeout="00:01:00" receiveTimeout="00:01:00" sendTimeout="00:01:00"
allowCookies="false" bypassProxyOnLocal="false" hostNameComparisonMode="StrongWildcard"
maxBufferPoolSize="2147483647" maxBufferSize="2147483647" maxReceivedMessageSize="2147483647"
textEncoding="utf-8" transferMode="Buffered" useDefaultWebProxy="false"
proxyAddress="http://myproxy:8080"
messageEncoding="Text">
<readerQuotas maxDepth="32" maxStringContentLength="2147483647"
maxArrayLength="16384" maxBytesPerRead="4096" maxNameTableCharCount="16384" />
<security mode="None">
<transport clientCredentialType="None" proxyCredentialType="None"
realm="" />
<message clientCredentialType="UserName" algorithmSuite="Default" />
</security>
</binding>
</basicHttpBinding>
</bindings>
