WCF：如何從配置中獲取綁定對象

我想從 web.config 或 app.config 中獲取 Binding 對象。

所以，這段程式碼有效：

wcfTestClient = new TestServiceClient("my_endpoint", Url + "/TestService.svc");

但我想做以下事情：

Binding binding = DoSomething();
wcfTestClient = new TestServiceClient(binding, Url + "/TestService.svc");

當然，我對 DoSomething() 方法很感興趣。

這個答案滿足了 OP 的要求，並且 100% 來自 Pablo M. Cibraro 的這篇精彩的文章。

此方法為您提供配置的綁定部分。

private BindingsSection GetBindingsSection(string path)
{
 System.Configuration.Configuration config = 
 System.Configuration.ConfigurationManager.OpenMappedExeConfiguration(
   new System.Configuration.ExeConfigurationFileMap() { ExeConfigFilename = path },
     System.Configuration.ConfigurationUserLevel.None);

 var serviceModel = ServiceModelSectionGroup.GetSectionGroup(config);
 return serviceModel.Bindings;
}

此方法為您提供了您Binding迫切需要的實際對象。

public Binding ResolveBinding(string name)
{
 BindingsSection section = GetBindingsSection(path);

 foreach (var bindingCollection in section.BindingCollections)
 {
   if (bindingCollection.ConfiguredBindings.Count > 0 
       && bindingCollection.ConfiguredBindings[0].Name == name)
   {
     var bindingElement = bindingCollection.ConfiguredBindings[0];
     var binding = (Binding)Activator.CreateInstance(bindingCollection.BindingType);
     binding.Name = bindingElement.Name;
     bindingElement.ApplyConfiguration(binding);

     return binding;
   }
 }

 return null;
}
