ASP.NET Routing(URL Rewriting ) with the help of Global.asax

Simply add a Global.asax page in our existing Asp.net project. Add System.Web.Routing namespace and write the following code on your global file. 

--------------------Start of Global.asax page-----------------------------------------------

<%@ Application Language="C#" %>

<%@ Import Namespace="System.Web.Routing" %>

<script runat="server">

    void Application_Start(object sender, EventArgs e)

    {

        // Code that runs on application startup

        RegisterRoutes(RouteTable.Routes);

    }

    public static void RegisterRoutes(RouteCollection routeCollection)

    {

        // Id is the parameter value that we can pass in url.

        routeCollection.MapPageRoute("RouteForArticle", "Reg/{Id}", "~/MemberReg.aspx");

    }

    void Application_End(object sender, EventArgs e)

    {

        //  Code that runs on application shutdown

    }

       

    void Application_Error(object sender, EventArgs e)

    {

        // Code that runs when an unhandled error occurs

    }

    void Session_Start(object sender, EventArgs e)

    {

        // Code that runs when a new session is started

    }

    void Session_End(object sender, EventArgs e)

    {

        // Code that runs when a session ends.

        // Note: The Session_End event is raised only when the sessionstate mode

        // is set to InProc in the Web.config file. If session mode is set to StateServer

        // or SQLServer, the event is not raised.

    }

      

</script>

---------------------------------End of Global.asax page-------------------------------------

The code of default.aspx.cs page

//We can get Id value by the following code.

if (this.Page.RouteData.Values["Id"] != null)

     {

         ViewState["Id"] = this.Page.RouteData.Values["Id"].ToString();

     }
