如何将代理凭据设置为特定的wcf客户端？

Question

我需要连接到一些公共wcf服务,但我和服务之间有一些代理.如果我使用默认代理设置,如

<system.net>
  <defaultProxy useDefaultCredentials="true" />
</system.net>

要么

HttpWebRequest.DefaultWebProxy

它工作得很好,但我不需要为整个应用程序设置代理设置,我需要为特定连接设置它.那我该怎么做呢？

我看到了ProxyAddress属性

(client.Endpoint.Binding as BasicHttpBinding).ProxyAddress

但是凭证没有任何属性......我想以某种方式修改HttpWebRequest,但我不知道怎么弄它...

解决了

谢谢大家的答案.

AntonK的答案适合解决我的问题.

在这个问题是实际的时候,我以同样的方式解决了它,但没有使用web.config并编写了这个方法

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;
}

这是一篇关于这个问题的文章.

总之,这是如何在web.config中为特定服务设置代理.在绑定配置中,设置proxyAddress ="http:// myproxy:8080"并设置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>
