using SPContext.Current.List

Scenario:
Someone asked me an interesting question , he said he knows about SPContext.Current.Site and SPContext.Current.Web objects and how to use them.

but he is confused where can we use SPContext.Currect.List or SPContext.Current.ListId etc.

Solution:
Its was pretty simple to quickly show him how to use it in a Custom Application List Setting page. Code below.

Note : In layout pages you need to pass the List=<ListGUID> as Query parameter
( Thanks for Chaitu for pointing it out )

Also you can use the list context in any webpart which is sitting on any list pages ( EditForm.aspx , DisplayForm.aspx or AllItems.aspx ) , here you need not to have anything Query parameter for the list guid

ASPX:

<%@ Assembly Name="SPCustomField, Version=1.0.0.0, Culture=neutral, PublicKeyToken=7668d5f62402984f"%> 
<%@ Page Language="C#"  Inherits="TestContext.ListSettingTest" MasterPageFile="~/_layouts/application.master"  %>

<asp:Content ID="Content1" ContentPlaceHolderId="PlaceHolderMain" runat="server">
<asp:Label ID="lblListName" runat="server" Text=""></asp:Label>
</asp:Content>

Codebehind:

using System;
using Microsoft.SharePoint;
using System.Web.UI.WebControls;

namespace TestContext
{
    public partial class ListSettingTest : System.Web.UI.Page
    {
        protected Label lblListName;
        protected void Page_Load(object sender, EventArgs e)
        {
            lblListName.Text = "List Name : " + SPContext.Current.List.Title;
        }
    }
}

Result:
