Hi All,
I have two or more classes called Dashboard, Order, Shipment and etc. I have a function to get list of all modules where i will be use same classes.
For example,

C#

public class Dashboard
    {
        public string Key { get; set; }
        public string Name { get; set; }
    }
    public class Order
    {
        public string OrderNo { get; set; }
        public string Buyer { get; set; }
    }
    public class Shipment
    {
        public string ShipmentNo { get; set; }
        public string Location { get; set; }
    }

 public List<object> GetList()
        {
<!-- Get List Code Here-->return lstobject;
        }

Is there possible to call GetList() method and return the wanted list object. For example, if i want dashboard list then return List<Dashboard> If i want order list then return List<Order>.

Please anyone help me to use this type of method.

The below code will verify if the object in list is dashboard, it will create the object of Dashboard class. The same can be applied on other classes too.

public static List<object> GetList()
{
   // Get List Code Here-->
   List<object> lstobject = new List<object>();
   lstobject.Add(new Dashboard());

   return lstobject;
}

To get the object use the following block

List<object> lstObject = GetList();
Dashboard ds=null;
for (int i = 0; < lstObject.Count; i++)
{
    if (lstObject[i] is Dashboard)
    {
        ds = (Dashboard)lstObject[i];
        Console.WriteLine(ds.Key);
    }
}

Hope this answer your question

Hi,

You can Use Like this.

public class getListClass
    {
        public static IList   getList()
        {
            List<Shipment> _lst = new List<Shipment>();
            Shipment _sh = new Shipment();
            _lst.Add(_sh);
            return _lst;             

        }
    }

List<Shipment> _ss = (List<Shipment>)getListClass.getList();

I have declare static only for test. You can use IEnumerable also instead of IList.
