This is my ActionResult
public ActionResult mytry()
{
Empoyee ee = new Empoyee();
ee.Address = "address1";
ee.Email = "email1";
ee.FirstName = "fname";
ee.Id = 23;
ee.LastName = "lname1";
ee.MiddleName = "";
ee.Salary = 20000;
db.Empoyees.Add(ee);
db.SaveChanges();
return View(ee);
}
View is
#model IEnumerable<trydbconnectMvc.Models.Empoyee>
#{
ViewBag.Title = "mytry";
}
<h2>mytry</h2>
<p>
#Html.ActionLink("Create New", "Create")
</p>
<table class="table">
<tr>
<th>
#Html.DisplayNameFor(model => model.FirstName)
</th>
<th>
#Html.DisplayNameFor(model => model.LastName)
</th>
<th>
#Html.DisplayNameFor(model => model.MiddleName)
</th>
<th>
#Html.DisplayNameFor(model => model.Address)
</th>
<th>
#Html.DisplayNameFor(model => model.Salary)
</th>
<th>
#Html.DisplayNameFor(model => model.Email)
</th>
<th></th>
</tr>
#foreach (var item in Model) {
<tr>
<td>
#Html.DisplayFor(modelItem => item.FirstName)
</td>
<td>
#Html.DisplayFor(modelItem => item.LastName)
</td>
<td>
#Html.DisplayFor(modelItem => item.MiddleName)
</td>
<td>
#Html.DisplayFor(modelItem => item.Address)
</td>
<td>
#Html.DisplayFor(modelItem => item.Salary)
</td>
<td>
#Html.DisplayFor(modelItem => item.Email)
</td>
<td>
#Html.ActionLink("Edit", "Edit", new { id=item.Id }) |
#Html.ActionLink("Details", "Details", new { id=item.Id }) |
#Html.ActionLink("Delete", "Delete", new { id=item.Id })
</td>
</tr>
}
</table>
I am getting error
" The model item passed into the dictionary is of type 'trydbconnectMvc.Models.Empoyee', but this dictionary requires a model item of type 'System.Collections.Generic.IEnumerable`1[trydbconnectMvc.Models.Empoyee]'."
I am new to mvc. How to solve this?

Answer 1

It seems you're returning only one entity, not a IEnumerable. Just change it in your view:
#model trydbconnectMvc.Models.Empoyee
#{
ViewBag.Title = "mytry";
}
<h2>mytry</h2>
<p>
#Html.ActionLink("Create New", "Create")
</p>
<table class="table">
<tr>
<th>
#Html.DisplayNameFor(model => model.FirstName)
</th>
<th>
#Html.DisplayNameFor(model => model.LastName)
</th>
<th>
#Html.DisplayNameFor(model => model.MiddleName)
</th>
<th>
#Html.DisplayNameFor(model => model.Address)
</th>
<th>
#Html.DisplayNameFor(model => model.Salary)
</th>
<th>
#Html.DisplayNameFor(model => model.Email)
</th>
<th></th>
</tr>
<tr>
<td>
#Html.DisplayFor(modelItem => #Model.FirstName)
</td>
<td>
#Html.DisplayFor(modelItem => #Model.LastName)
</td>
<td>
#Html.DisplayFor(modelItem => #Model.MiddleName)
</td>
<td>
#Html.DisplayFor(modelItem => #Model.Address)
</td>
<td>
#Html.DisplayFor(modelItem => #Model.Salary)
</td>
<td>
#Html.DisplayFor(modelItem => #Model.Email)
</td>
<td>
#Html.ActionLink("Edit", "Edit", new { id=#Model.Id }) |
#Html.ActionLink("Details", "Details", new { id=#Model.Id }) |
#Html.ActionLink("Delete", "Delete", new { id=#Model.Id })
</td>
</tr>
}
</table>
or if you want, just change in your Controller:
public ActionResult mytry()
{
Empoyee ee = new Empoyee();
ee.Address = "address1";
ee.Email = "email1";
ee.FirstName = "fname";
ee.Id = 23;
ee.LastName = "lname1";
ee.MiddleName = "";
ee.Salary = 20000;
db.Empoyees.Add(ee);
db.SaveChanges();
var list = new List<Empoyee>(){ ee };
return View(list );
}
and keep your current view.

If you must use an IEnumerable, you can make a List<> and pass it in
public ActionResult mytry()
{
Empoyee ee = new Empoyee();
ee.Address = "address1";
ee.Email = "email1";
ee.FirstName = "fname";
ee.Id = 23;
ee.LastName = "lname1";
ee.MiddleName = "";
ee.Salary = 20000;
db.Empoyees.Add(ee);
db.SaveChanges();
List<Employee> employees = new List<Employee>();
employees.add(ee);
return View(employees);
}
