次のメソッドを呼び出すコントローラーにアクションがあります。
public IQueryable<AaaUserContactInfo> getcontactinfo(long[] id)
{
var organizationsiteids = from accountsitemapping in entities.AccountSiteMappings
where id.Any(accountid => accountsitemapping.ACCOUNTID == accountid)
select accountsitemapping.SITEID;
var usersdepts = from userdept in entities.UserDepartments
join deptdefinition in entities.DepartmentDefinitions on userdept.DEPTID equals deptdefinition.DEPTID
where organizationsiteids.Any(accountid => deptdefinition.SITEID == accountid)
select userdept;
var contactsinfos = from userdept in usersdepts
join contactinfo in entities.AaaUserContactInfoes on userdept.USERID equals contactinfo.USER_ID
select contactinfo;
return contactsinfos;
}
しかし、アプリケーションを実行してアクション メソッドに移動すると、ビュー レベルで次のエラーが発生します。
