AssemblyCollection 类
定义
重要
一些信息与预发行产品相关，相应产品在发行之前可能会进行重大修改。 对于此处提供的信息，Microsoft 不作任何明示或暗示的担保。
表示 AssemblyInfo 对象集合。 此类不能被继承。
public ref class AssemblyCollection sealed : System::Configuration::ConfigurationElementCollection[System.Configuration.ConfigurationCollection(typeof(System.Web.Configuration.AssemblyInfo))]
public sealed class AssemblyCollection : System.Configuration.ConfigurationElementCollection[<System.Configuration.ConfigurationCollection(typeof(System.Web.Configuration.AssemblyInfo))>]

示例
本部分提供两个代码示例。 第一个演示如何以声明方式指定类的 AssemblyCollection 多个属性的值。 第二个演示了如何使用类的成员 AssemblyCollection 。
以下配置文件示例演示如何以声明方式指定类的 AssemblyCollection 多个属性的值。
