备注

从此方法返回的配置实例才有效，直至下一个 ConfigurationChanged 事件生成。

示例

下面的代码示例演示如何使用 LoadConfiguration 方法修改配置文件。

/// Make sure that our custom WSDL importer extension is registered in /// the Metadata section of the configuration file for the current 
/// project hierarchy and serviceProvider that gives access to required 
/// services.
private static void EnsureCustomWsdlImporterRegistered
 (IVsHierarchy hierarchy, IServiceProvider serviceProvider)
{
    /// The IVsApplicationConfigurationManager service returns a 
    /// System.Configuration.Configuration object corresponding to 
    /// the given project's app.config or web.config file.
    IVsApplicationConfigurationManager cfgMgr = 
 serviceProvider.GetService(typeof(IVsApplicationConfigurationManager))
 as IVsApplicationConfigurationManager;
    // Return the current application's configuration file by using 
    // the IVsApplicationConfiguration APIs. Make sure that the 
    // instance that is returned is disposed of correctly in order 
    // to clean up any event hooks or docdatas.
    using (IVsApplicationConfiguration appCfg = 
 cfgMgr.GetApplicationConfiguration(hierarchy, 
 Microsoft.VisualStudio.VSConstants.VSITEMID_ROOT))
    {
        System.Configuration.Configuration cfg = 
 appCfg.LoadConfiguration();

        // Check the file out from Source Code Control if it 
        // exists.
        appCfg.QueryEditConfiguration();

        /// After a System.Configuration.Configuration object
        /// exists, use the"normal" .NET Framework configuration
        /// APIs to return the sections that you want to modify.
        ServiceModelSectionGroup sg = 
 ServiceModelSectionGroup.GetSectionGroup(cfg);
        Type importerType = typeof(BindingPickerWsdlImportExtension);
        if (!IsWsdlImporterRegistered(sg, importerType))
        {
            // If our custom WSDL importer is not registered, add 
            // it to the application's configuration file.
            sg.Client.Metadata.WsdlImporters.Add(new 
 WsdlImporterElement(importerType));
            cfg.Save();
        }
    }
}
