Highlight current page link on asp.net

How to highlight current page or link in asp.net.

Let's see it.

I have a site.master page like below.
-------------------------

<head runat="server">

    <title></title>
    <asp:ContentPlaceHolder ID="ContentPlaceHolder1" runat="server">
    </asp:ContentPlaceHolder>
</head>

<body>
    <form id="form1" runat="server">
    <table><tr>
            <td><asp:LinkButton ID="LinkButton2" runat="server" PostBackUrl="~/WebForm1.aspx">Page2</asp:LinkButton></td>
           <td><asp:LinkButton ID="LinkButton3" runat="server" PostBackUrl="~/WebForm2.aspx">Page3</asp:LinkButton></td>
        </tr></table>
    <div>
        <asp:ContentPlaceHolder ID="ContentPlaceHolder2" runat="server">
        </asp:ContentPlaceHolder>
     
       
    </div>
    </form>
</body>
------------------------------------------------------------
Now on site.master.cs file write following code.


  public partial class Site1 : System.Web.UI.MasterPage
    {
        protected void Page_Load(object sender, EventArgs e)
        {

        }
        public void changecolor(Page obj)
        {
            if (obj is WebForm1)
            {
                LinkButton2.ForeColor = Color.Green;
                LinkButton3.ForeColor = Color.Empty;

            }
            if (obj is WebForm2)
            {
                LinkButton2.ForeColor = Color.Empty;
                LinkButton3.ForeColor = Color.Green;

            }
        }
    }
---------------------------------------------------------
Now on each page load event write just following code.


 protected void Page_Load(object sender, EventArgs e)
        {
            if (!IsPostBack)
            {
                Site1 myMasterPage = (Site1)Page.Master;
                myMasterPage.changecolor(this.Page);
            }
        }
--------

Create sharepoint list programmatically

I have written a sample code showing how to create custom sharepoint list programmatically .

-------------------------------------
            SPSite site = new SPSite("URL");
            SPWeb web = site.OpenWeb();
            SPListCollection lists = web.Lists;
            lists.Add("Programmatically List", "Here the list is being created programmatically", SPListTemplateType.GenericList);
            SPList newList = web.Lists["Programmatically List"];
            newList.Fields.Add("My Column", SPFieldType.Text, true);
            newList.Fields.Add("DOB", SPFieldType.DateTime, true);
           
           // Lookup from another list and adding that column along with the fileds present
            SPList targetList = web.Lists["InfoValidation"];
            newList.Fields.AddLookup("Message", targetList.ID, false);
            SPFieldLookup lkp = (SPFieldLookup)newList.Fields["Message"];
            lkp.LookupField = targetList.Fields["Message"].InternalName;
            lkp.Update();

            SPView view = newList.DefaultView;
            view.ViewFields.Add("My Column");
            view.ViewFields.Add("DOB");
            view.ViewFields.Add("Message");
            view.Update();
            Console.WriteLine("List Created Successfully");
