如何在代码中使用 wsDualHttpBinding 设置 WCF 客户端? [英] How to set up a WCF client using wsDualHttpBinding in code?

问题描述

我需要连接到我编写的 WCF 服务，而不必为我正在编写的客户端应用程序部署 app.config.但是，我一直在尝试弄清楚如何在代码中从客户端进行设置时遇到了非常困难的时间.这就是我所得到的......有没有人知道我需要做什么才能让它发挥作用?我真的很感激.

I have a need to connect to a WCF service I wrote without having to deploy an app.config for the client application I'm writing. However, I've been having a very difficult time trying to figure out how to set up things from the client side in code. This is as far as I've gotten... does anyone have any ideas what I need to do to get this to work? I'd really appreciate it.

这是我目前得到的代码:

This is the code I've got so far:

    String baseAddress = "http://localhost/CommService";

    WSDualHttpBinding binding = new WSDualHttpBinding();
    binding.Name = "WSDualHttpBinding_ICommService";
    binding.ClientBaseAddress = new Uri(baseAddress);
    binding.ReliableSession.Ordered = true;
    binding.ReliableSession.InactivityTimeout = new TimeSpan(0, 10, 0);
    binding.ReceiveTimeout = new TimeSpan(0, 10, 0);
    binding.SendTimeout = new TimeSpan(0, 0, 5);

    InstanceContext context = new InstanceContext(this);
    client = new CommServiceClient(context, "WSDualHttpBinding_ICommService");
    client.Endpoint.Binding = binding;

这是我的客户端应用的 app.config:

And this is my client app's app.config:

<system.serviceModel>
    <bindings>
        <wsDualHttpBinding>
            <binding name="WSDualHttpBinding_ICommService" closeTimeout="00:01:00"
                openTimeout="00:01:00" receiveTimeout="00:10:00" sendTimeout="00:00:05"
                bypassProxyOnLocal="false" transactionFlow="false" hostNameComparisonMode="StrongWildcard"
                maxBufferPoolSize="524288" maxReceivedMessageSize="65536"
                messageEncoding="Text" textEncoding="utf-8" useDefaultWebProxy="true">
                <readerQuotas maxDepth="32" maxStringContentLength="8192" maxArrayLength="16384"
                    maxBytesPerRead="4096" maxNameTableCharCount="16384" />
                <reliableSession ordered="true" inactivityTimeout="00:10:00" />
                <security mode="Message">
                    <message clientCredentialType="Windows" negotiateServiceCredential="true"
                        algorithmSuite="Default" />
                </security>
            </binding>
        </wsDualHttpBinding>
    </bindings>
    <client>
        <endpoint address="http://localhost/CommService/"
            binding="wsDualHttpBinding" bindingConfiguration="WSDualHttpBinding_ICommService"
            contract="Services.ICommService" name="WSDualHttpBinding_ICommService">
            <identity>
                <dns value="localhost" />
            </identity>
        </endpoint>
    </client>
</system.serviceModel>

推荐答案

您可以轻松实现您想要的.见下面的代码:

You can easily achieve what you want. See code below :

 Uri baseAddress = new Uri("http://localhost/CommService");
 WSDualHttpBinding wsd = new WSDualHttpBinding();
 EndpointAddress ea = new EndpointAddress(baseAddress, EndpointIdentity.CreateDnsIdentity("localhost"));
 client  = new CommServiceClient(new InstanceContext(this), wsd, ea);

让我解释一下:

• 首先，我们使用默认设置创建一个 WSDualHttpBinding 实例(这些是生成的 app.config 所具有的确切设置).如果要修改任何设置，可以通过公开的属性进行修改.
• 然后我们创建一个具有所需 URL 和身份的 EndPointAddress.无需使用绑定链接它，因为我们将在服务客户端构造函数中链接所有这些.
• 最后我们创建了服务客户端.构造函数重载之一允许我们指定绑定和端点地址.
• 一般来说，app.config 文件中的每个可用元素在 .NET 代码中都有一个关联的类，并且每个属性或子元素在指定的类中都有一个关联的属性.
