我是靠谱客的博主勤奋书包，最近开发中收集的这篇文章主要介绍Microsoft.Practices.Unit在Web应用程序中的使用，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

直接上代码

Web.config

Global.asax

public class Global : System.Web.HttpApplication
    {
        private const string AppContainerKey = "application container";
        private const string SessionContainerKey = "session container";

        protected void Application_Start(object sender, EventArgs e)
        {
            IUnityContainer applicationContainer = new UnityContainer();
            applicationContainer.LoadConfiguration("application");

            ApplicationContainer = applicationContainer;
        }

        protected void Application_End(object sender, EventArgs e)
        {
            IUnityContainer applicationContainer = this.ApplicationContainer;

            if (applicationContainer != null)
            {
                applicationContainer.Dispose();

                this.ApplicationContainer = null;
            }
        }

        protected void Application_PreRequestHandlerExecute(object sender, EventArgs e)
        {
            Page handler = HttpContext.Current.Handler as Page;

            if (handler != null)
            {
                IUnityContainer container = SessionContainer;

                if (container != null)
                {
                    container.BuildUp(handler.GetType(), handler);
                }
            }
        }

        protected void Session_Start(object sender, EventArgs e)
        {
            IUnityContainer applicationContainer = this.ApplicationContainer;

            if (applicationContainer != null)
            {
                IUnityContainer sessionContainer
                    = applicationContainer.CreateChildContainer();
                sessionContainer.LoadConfiguration("session");

                this.SessionContainer = sessionContainer;
            }
        }

        protected void Session_End(object sender, EventArgs e)
        {
            IUnityContainer sessionContainer = this.SessionContainer;
            if (sessionContainer != null)
            {
                sessionContainer.Dispose();

                this.SessionContainer = null;
            }
        }

        private IUnityContainer ApplicationContainer
        {
            get
            {
                return (IUnityContainer)this.Application[AppContainerKey];
            }
            set
            {
                this.Application[AppContainerKey] = value;
            }
        }

        private IUnityContainer SessionContainer
        {
            get
            {
                return (IUnityContainer)this.Session[SessionContainerKey];
            }
            set
            {
                this.Session[SessionContainerKey] = value;
            }
        }
    }
