The model item passed into the dictionary is of type 'system.collections.generic.list`1[dempproject.models.user]', but this dictionary requires a model item of type 'dempproject.models.admin'.

I have Error:

System.InvalidOperationException: The model item passed into the dictionary is of type 'System.Collections.Generic.List`1[Dempproject.Models.user]', but this dictionary requires a model item of type 'Dempproject.Models.admin'.

What I have tried:

controller codeing:

public ActionResult view()
     {

         List<user> lmd = new List<user>();  // creating list of model.

         DataSet ds = new DataSet();



         Connection con = new Connection();

         ds = con.mydata(); // fill dataset

         foreach (DataRow dr in ds.Tables[0].Rows) // loop for adding add from dataset to list<modeldata>
         {
             lmd.Add(new user
             {
                 username = dr["Username"].ToString(),// adding data from dataset row in to list<modeldata>
                 Userid = dr["Userid"].ToString(),
                 email = dr["Email"].ToString(),
                 Groupname = dr["groupName"].ToString(),
                 customerno = dr["CustomerNo"].ToString(),
                 Password_1 = dr["Password1"].ToString(),
                 phoneno = dr["Phoneno"].ToString(),
                 Faxno = dr["Faxno"].ToString()


             });
         }
         return View(lmd.AsEnumerable());

     }

view codeing:

@model  IEnumerable<Dempproject.Models.user>
