Make reusable Method to access in any Controller in ASP.Net MVC

Hi Shubh4m,

You you need to make different class for this method and then call this method in any controller.

Sorry, but i think i was missing assembly 

using System.Data.Entity;

Base.cs 

using CRM.Models;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;
using System.Data.Entity;

namespace CRM.Controllers
{
public class Base : Controller
    {
        private ScriptEntities db = new ScriptEntities();

        public List<CustomerModel> getDetails()
        {
            var cust = (from c in db.Customers.Include(c => c.CUSTOMERTYPE)
                        join ch in db.CUSTOMERHEADs on c.Id equals ch.CustomerId into ps
                        from ch in ps.DefaultIfEmpty()
                        select new
                        {
                            id = c.Id,
                            name = c.Name,
                            company = c.Company,
                            mb1 = c.Mb1,
                            address = c.Address,
                            date_ = c.Date_,
                            origin = c.Origin,
                            type = c.CUSTOMERTYPE.Type_,
                            voucherno = ch.VoucherNo,
                        });

            var details = new List<CustomerModel>();
            foreach (var t in cust)
            {
                details.Add(new CustomerModel()
                {
                    Id = t.id,
                    Name = t.name,
                    Company = t.company,
                    Mb1 = t.mb1,
                    Address = t.address,
                    Date_ = t.date_,
                    Origin = t.origin,
                    Type_ = t.type,
                });
            }
            return details;
        }
    }

Now i can access my method in my controllers.

Controller Class:

using System;
using System.Collections.Generic;
using System.Data;
using System.Data.Entity;
using System.Linq;
using System.Net;
using System.Web;
using System.Web.Mvc;
using CRM.Models;

namespace CRM.Controllers
{
    public class MasterController : Base
    {
        private ScriptEntities db = new ScriptEntities();
        // GET: Customers
        public ActionResult Index()
        {
            var details = getDetails();
            var customers = db.Customers.Include(c => c.CUSTOMERTYPE);
            return View(details);
        }
}
