I have the following view inside my asp.net mvc application:-
@model MvcApplication4.Models.ContactsDetails
<h3>Select Contacts Detials</h3>
<p class="dashboarder" style = "color:#5c87b2"><strong>@Model.Info.Count()</strong> Selected Customers Accounts.</p>
@using (Html.BeginForm("Export", null))
{
Int32 c = -1;
<table>
<tr>
<th>
Account Name @Html.CheckBox("IncludeAccountName", true)
</th>
<th>
Name @Html.CheckBox("IncludeName", true)
</th>
which is populated using the following action method:-
public ActionResult CustomersDetails(long[] SelectRight)
{
if (SelectRight == null)
{
return RedirectToAction("customer", new { isError = true });
}
else
{
var ContactsDetails2 = new ContactsDetails
{
Info = r.getcontactinfo(SelectRight)
};
return View(ContactsDetails2);
}
}
and then the following repository method:-
public IEnumerable<AaaUserContactInfo> getcontactinfo(long[] id)
{
var organizationNames = entities.SDOrganizations
.Where(org => id.Contains(org.ORG_ID))
.Select(org => org.NAME);
var result = from userContactInfo in entities.AaaUserContactInfoes
join contactInfo in entities.AaaContactInfoes on userContactInfo.CONTACTINFO_ID equals contactInfo.CONTACTINFO_ID
where organizationNames.Contains(contactInfo.EMAILID.ToString())
select userContactInfo;
return result;
but when i run mu application i got th folloiwng unclear error on the view :-
LINQ to Entities does not recognize the method 'System.String ToString()' method, and this method cannot be translated into a store expression.
on the following code:-
<strong>@Model.Info.Count()</strong>
Use SqlFunctions.StringConvert
method instead of ToString
(which cannot be converted into SQL):
where organizationNames.Contains(SqlFunctions.StringConvert(contactInfo.EMAILID))
If EMAILID
is not double or decimal, then just cast value to one of those types.
