有没有人知道如何在不使用配置文件的情况下以编程方式公开WCF服务的好例子?我知道服务对象模型现在使用WCF更丰富,所以我知道它是可能的。我只是没有看到如何这样做的例子。相反,我希望看到没有配置文件的消费也是如此。
在有人要求之前,我有一个非常具体的需要,没有配置文件。我通常不会推荐这样的做法,但正如我所说,在这种情况下有一个非常具体的需要。

正如我所发现的那样,使用没有配置文件的Web服务非常简单。您只需创建一个绑定对象和地址对象,并将它们传递给客户端代理的构造函数或通用的ChannelFactory实例。您可以查看默认的app.config以查看要使用的设置,然后在实例化代理的地方创建一个静态帮助器方法:
internal static MyServiceSoapClient CreateWebServiceInstance() {
BasicHttpBinding binding = new BasicHttpBinding();
// I think most (or all) of these are defaults--I just copied them from app.config:
binding.SendTimeout = TimeSpan.FromMinutes( 1 );
binding.OpenTimeout = TimeSpan.FromMinutes( 1 );
binding.CloseTimeout = TimeSpan.FromMinutes( 1 );
binding.ReceiveTimeout = TimeSpan.FromMinutes( 10 );
binding.AllowCookies = false;
binding.BypassProxyOnLocal = false;
binding.HostNameComparisonMode = HostNameComparisonMode.StrongWildcard;
binding.MessageEncoding = WSMessageEncoding.Text;
binding.TextEncoding = System.Text.Encoding.UTF8;
binding.TransferMode = TransferMode.Buffered;
binding.UseDefaultWebProxy = true;
return new MyServiceSoapClient( binding, new EndpointAddress( "http://www.mysite.com/MyService.asmx" ) );
}

如果您有兴趣消除IIS主机的web.config中System.ServiceModel部分的使用,我已在此处发布了一个示例(http://bejabbers2.blogspot.com/2010/02/wcf-zero-config-in-net-35-part-ii.html)。我将展示如何自定义ServiceHost以创建元数据和wshttpbinding端点。我是以通用的方式进行的,不需要额外的编码。对于那些没有立即升级到.NET 4.0的人来说,这可能非常方便。

在这里,这是完整且有效的代码。我认为它会对你有很大帮助。我正在搜索,从来没有找到完整的代码,这就是为什么我试图提供完整和有效的代码。祝你好运。

服务器上side ..
并不容易对于客户端,您可以使用ChannelFactory
答案 4 :(得分:3)
所有WCF配置都可以以编程方式完成。因此,可以在没有配置文件的情况下创建服务器和客户端。
我推荐Juval Lowy的“Programming WCF Services”一书,其中包含许多程序化配置的例子。
答案 5 :(得分:2)
我在下面的链接中找到了关于此主题的博文非常有趣。
我喜欢的一个想法是能够将绑定或行为或地址XML部分从配置传递到适当的WCF对象,并让它处理属性的分配 - 目前你不能这样做。
与网络上的其他人一样,我遇到的问题是需要我的WCF实现使用与我的托管应用程序(.NET 2.0 Windows服务)不同的配置文件。

答案 6 :(得分:2)
在客户端和服务器端都很容易。 Juval Lowy的书中有很好的例子。
至于你对配置文件的评论,我会说配置文件是穷人在代码中做的第二个。当您控制将连接到您的服务器的每个客户端并确保它们已更新,并且用户无法找到它们并进行任何更改时,配置文件非常有用。我发现WCF配置文件模型是限制性的,设计起来有点困难,而且是维护的噩梦。总而言之,我认为MS决定将配置文件作为默认的处理方式是一个非常糟糕的决定。
编辑:配置文件无法做的一件事是使用非默认构造函数创建服务。这导致WCF中的静态/全局变量和单例以及其他类型的无意义。
