ViewModel In MVC 4

Question

I have a simple website build in MVC4 I do not know how to use multiple models in a single view so Now I have two models used on one view so i made a ViewModel 

public class viewModelVm

{

public List<slider> slider { get; set; }

public List<Service> Service { get; set; }

}

my service class and slider class is also shown below

public class Service

{

public int ID { get; set; }

public string Name { get; set; }

public string Description { get; set; }

public string Image { get; set; }

public List<Service> Getdata()

{

String connectionString = "Data Source=ASPKCO-DANISH\\SQLEXPRESS1;Initial Catalog=PakeezaSodagran;Integrated Security=True;";

String sql = "SELECT * FROM Service";

using (SqlConnection conn = new SqlConnection(connectionString))

{

SqlCommand cmd = new SqlCommand(sql, conn);

conn.Open();

SqlDataReader rdr = cmd.ExecuteReader();

var model = new List<Service>();

while (rdr.Read())

{

var service = new Service();

service.ID = Convert.ToInt32(rdr["ID"]);

service.Name = rdr["Name"].ToString();

service.Description = rdr["Description"].ToString();

service.Image = rdr["Image"].ToString();

model.Add(service);

}

return model;

}

}

}

my slider class is as below

public class slider

{

public string src { get; set; }

public string title { get; set; }

}

Now I have a main page in which i have a link for service page and my service controller code is given below

public ActionResult Index()

{

Service sr=new Service();

viewModelVm vm = new viewModelVm();

vm.Service = sr.Getdata();

return View(vm);

}

 

My Service Index View is below 

@model List<BusinessApplicationTemplate.ViewModel.viewModelVm>

<table>

<tr>

<th>ID</th>

<th>Name</th>

<th>Description</th>

<th>Image</th>

</tr>

@foreach (var Service in Model.Service)

{

<tr>

<td>@Service.ID</td>

<td>@Service.Name</td>

<td>@Service.Description</td>

<td>@Service.Image</td>

</tr>

}

</table>

when i click the service link i am getting that error

"'System.Collections.Generic.List<BusinessApplicationTemplate.ViewModel.viewModelVm>' does not contain a definition for 'Service' and no extension method 'Service' accepting a first argument of type 'System.Collections.Generic.List<BusinessApplicationTemplate.ViewModel.viewModelVm>' could be found (are you missing a using directive or an assembly reference?)"
