装载系统。ServiceModel构成部分使用ConfigurationManager

Question

使用。净3.5和周我试着写出一些WCF构在客户应用程序(姓名的客户服务器连接)。

显而易见的方法是使用 ConfigurationManager 载的构成部分，并写出来的数据需要。

var serviceModelSection = ConfigurationManager.GetSection("system.serviceModel");

似乎总是返回null。

var serviceModelSection = ConfigurationManager.GetSection("appSettings");

完美的作品。

该构成部分是存在的应用程序。config但由于某些原因 ConfigurationManager 拒绝装载 system.ServiceModel 部分。

我想要避免手动装xxx.exe。配置文件和使用XPath但是，如果我们要，我会的。似乎只是一点的一个黑客。

任何建议？

Answer 1

的 <system.serviceModel> 元是用于一个构成部分 小组, 不一部分。你需要用到 System.ServiceModel.Configuration.ServiceModelSectionGroup.GetSectionGroup() 得到整个集团。

// 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。

这是我一直在寻找什么感谢@marxidad为指针。

    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;
    }

Answer 4

GetSectionGroup()不支持没有参数(下框架3.5).

而不是使用：

Configuration config = System.Configuration.ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None);
ServiceModelSectionGroup group = System.ServiceModel.Configuration.ServiceModelSectionGroup.GetSectionGroup(config);

感谢其他的海报，这是我的开发，以获得URI的一个名为终点。它还创建了一系列的终点使用和实际配置文件被使用时调试：

Private Function GetEndpointAddress(name As String) As String
    Debug.Print("--- GetEndpointAddress ---")
    Dim address As String = "Unknown"
    Dim appConfig As Configuration = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None)
    Debug.Print("app.config: " & appConfig.FilePath)
    Dim serviceModel As ServiceModelSectionGroup = ServiceModelSectionGroup.GetSectionGroup(appConfig)
    Dim bindings As BindingsSection = serviceModel.Bindings
    Dim endpoints As ChannelEndpointElementCollection = serviceModel.Client.Endpoints
    For i As Integer = 0 To endpoints.Count - 1
        Dim endpoint As ChannelEndpointElement = endpoints(i)
        Debug.Print("Endpoint: " & endpoint.Name & " - " & endpoint.Address.ToString)
        If endpoint.Name = name Then
            address = endpoint.Address.ToString
        End If
    Next
    Debug.Print("--- GetEndpointAddress ---")
    Return address
End Function
