ASP.Net MVC Error: The model item passed into the dictionary is of type System.Collections.Generic.List

Hello,

i have method to pass the data from Data access method to controller

when i load the page with parameter value 1 it gives following error

The model item passed into the dictionary is of type 'System.Collections.Generic.List`1[BussinessObject.UserBO]', but this dictionary requires a model item of type 'BussinessObject.UserBO'.

public ActionResult Edit()
{
            
    var id = HttpContext.Request.RequestContext.RouteData.Values["id"];
    if (id == null)
    {
        return new HttpStatusCodeResult(HttpStatusCode.BadRequest);
    }
    //UserBO userBO = userbl.fetchbl();
    IList<UserBO> objAddressDetails = new List<UserBO>();
    objAddressDetails = userbl.fetchbl(int.Parse(id.ToString()));
    if (objAddressDetails == null)
    {
        return HttpNotFound();
    }
    return View(objAddressDetails);
}

 Edit html page which has strongly type model with Userbo class

@model BussinessObject.UserBO
@{
    ViewBag.Title = "Edit";
}

<h2>Edit</h2>

@using (Html.BeginForm())
{
   ......
}

<div>
    @Html.ActionLink("Back to List", "Index")
</div>
