关于c＃：使用ConfigurationManager加载System.ServiceModel配置部分

2023-04-12 17:27:00

Loading System.ServiceModel configuration section using ConfigurationManager

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。

public static string GetServerName()
{
string serverName ="Unknown";

Configuration appConfig = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None);
ServiceModelSectionGroup serviceModel = ServiceModelSectionGroup.GetSectionGroup(appConfig);
BindingsSection bindings = serviceModel.Bindings;

ChannelEndpointElementCollection endpoints = serviceModel.Client.Endpoints;

for(int i=0; i<endpoints.Count; i++)
{
ChannelEndpointElement endpointElement = endpoints[i];
if (endpointElement.Contract =="MyContractName")
{
serverName = endpointElement.Address.Host;
}
}

return serverName;
}

GetSectionGroup()不支持任何参数(在框架3.5下)。

而是使用：

1 2	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：
