没有配置文件的WCF配置

Question

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服务的一个很好的例子？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.

Answer 1

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,我已经发布了一个如何在此处执行此操作的示例(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.祝好运.

在服务器端并不容易..

对于客户端,您可以使用ChannelFactory
