在CommonServiceLocator的评论中，ambient是什么意思？ [英] What is the meaning of the word ambient in this comment from CommonServiceLocator?

问题描述

我想猜测环境容器与它是一个静态类的事实有关，但这只是一个猜测。

到标准模式？ （即我真的需要阅读GoF的封面来覆盖）

 命名空间Microsoft.Practices.ServiceLocation 
 {
 ///< summary> 
 ///此类为此应用程序提供了环境容器。如果你的
 ///框架定义了这样一个环境容器，使用ServiceLocator.Current 
 ///得到它。 
 ///< / summary> 
 public static class ServiceLocator 
 {
 private static ServiceLocatorProvider currentProvider; 
 
 ///< summary> 
 ///当前环境容器。 
 ///< / summary> 
 public static IServiceLocator当前
 {
 get {return currentProvider（）; } 
} 
 
 ///< summary> 
 ///设置用于检索当前容器的代理。 
 ///< / summary> 
 ///< param name =newProvider>委托，调用时将返回
 ///当前环境容器。< / param> 
 public static void SetLocatorProvider（ServiceLocatorProvider newProvider）
 {
 currentProvider = newProvider; 
} 
} 
} 
  

解决方案>

是的，环境应该是指共享，可供所有人。

如果您需要来自DI周围的引用，请搜索环境上下文模式，例如Mark Seemann的Dependency Injection in .NET

I want to guess that "ambient container" has something to do with the fact that it's a static class, but that's just a guess.

Or is this referring to a standard pattern? (i.e. I really need to read that GoF book cover to cover)

namespace Microsoft.Practices.ServiceLocation
{
    /// <summary>
    /// This class provides the ambient container for this application. If your
    /// framework defines such an ambient container, use ServiceLocator.Current
    /// to get it.
    /// </summary>
    public static class ServiceLocator
    {
        private static ServiceLocatorProvider currentProvider;

        /// <summary>
        /// The current ambient container.
        /// </summary>
        public static IServiceLocator Current
        {
            get { return currentProvider(); }
        }

        /// <summary>
        /// Set the delegate that is used to retrieve the current container.
        /// </summary>
        /// <param name="newProvider">Delegate that, when called, will return
        /// the current ambient container.</param>
        public static void SetLocatorProvider(ServiceLocatorProvider newProvider)
        {
            currentProvider = newProvider;
        }
    }
}

解决方案

Yep, "ambient" is supposed to mean "shared, available to everyone".

If you need a reference from somewhere around the DI, search for the "Ambient Context" pattern, described for example in Mark Seemann's "Dependency Injection in .NET" book.
