使用C＃.NET 3.5和WCF，我试图在客户端应用程序(客户端连接到的服务器的名称)中写出一些WCF配置。
显而易见的方法是使用ConfigurationManager加载配置节并写出我需要的数据。
1
| var serviceModelSection = ConfigurationManager.GetSection("system.serviceModel"); |
似乎总是返回null。
1
| var serviceModelSection = ConfigurationManager.GetSection("appSettings"); |
完美运作。
App.config中存在配置节，但由于某些原因ConfigurationManager拒绝加载system.ServiceModel节。
我想避免手动加载xxx.exe.config文件并使用XPath，但是如果需要的话，我会这样做。 似乎有点hack。
有什么建议么？

| // Automagically find all client endpoints defined in app.config
ClientSection clientSection =
ConfigurationManager.GetSection("system.serviceModel/client") as ClientSection;
ChannelEndpointElementCollection endpointCollection =
clientSection.ElementInformation.Properties[string.Empty].Value as ChannelEndpointElementCollection;
List<string> endpointNames = new List<string>();
foreach (ChannelEndpointElement endpointElement in endpointCollection)
{
endpointNames.Add(endpointElement.Name);
}
// use endpointNames somehow ... |
似乎运作良好。
元素用于配置节组，而不是节。 您需要使用System.ServiceModel.Configuration.ServiceModelSectionGroup.GetSectionGroup()来获取整个组。
这就是我一直在寻找的东西，感谢@marxidad提供的指针。

GetSectionGroup()不支持任何参数(在框架3.5下)。
而是使用：

| Configuration config = System.Configuration.ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None);
ServiceModelSectionGroup group = System.ServiceModel.Configuration.ServiceModelSectionGroup.GetSectionGroup(config); |
感谢其他张贴者，这是我开发的用于获取命名端点的URI的功能。 它还会创建正在使用的端点的列表，以及调试时正在使用的实际配置文件：
