从流而不是文件加载配置文件

不。 Configuration 类来加载配置,而这个类实际上需要一个物理路径。

对。 如果允许应用程序更改应用程序文件夹中的文件-更新 *.config update / save / refresh

示例:假设您存储了wcf部分的组( <bindings> , <behaviors> .. 等)在文件中 wcfsections.test.config

        Configuration config = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None);
        ConfigurationSectionCollection sections = ServiceModelSectionGroup.GetSectionGroup(config).Sections;
        sections.Clear();

        string fileName = ((GeneralSettings)ConfigurationManager.GetSection("generalSettings")).AppConfigServiceModelSectionFile;

        XDocument doc = XDocument.Load(fileName);
        var xmlGroup = (from x in doc.Descendants("system.serviceModel") select x).FirstOrDefault();

        string[] sectionsInUpdateOrder = { "bindings", "comContracts", "behaviors", "extensions", "services", "serviceHostingEnvironment", "client", "diagnostics" };
        foreach (string key in sectionsInUpdateOrder)
        {
            var e = (from x in xmlGroup.Elements(key) select x).FirstOrDefault();
            if (e != null)
            {
                ConfigurationSection currentSection = sections[e.Name.LocalName];
                string xml = e.ToString();
                currentSection.SectionInformation.SetRawXml(xml);
            }
        }
        config.Save();
        foreach (string key in sectionsInUpdateOrder)
            ConfigurationManager.RefreshSection("system.serviceModel/" + key);
