Getting Error in List

I know this is basic question.Need help getting error in List using foreach storing data in List but in the end it give me error that _obj does not exist in the context

I have ActionResult Page

public ActionResult Index()
{
    var _objAdd = new C();
    var Get_ClientInfor = example();

    foreach (var item in Get_ClientInfor)
    {
        var _obj = new List<C>();

        _objAdd.FirstName = item.Clients.FirstName;
        _objAdd.LastName = item.Clients.LastName;
        if (item.Clients.DateBirth != null)
            _objAdd.Dob = item.Clients.DateBirth.Value;
        _objAdd.Gender = item.ClientDemographics.Gender;


        _obj.Add(_objAdd);
    }

    return View(_obj); //error ===>>>
}

Getting Error that _obj does not exist in the context.

You put the _obj variable on foreach, you will only be able to use it in the method. Your need to declare outside the iteration.

You need to swap _objAdd and _obj declarations because _objAdd is an item you want to add to collection in foreach loop and _obj is a collection you want to return:

public ActionResult Index()
{
    var _obj = new List<C>();
    var Get_ClientInfor = example();

    foreach (var item in Get_ClientInfor)
    {
        var _objAdd = new C();

        _objAdd.FirstName = item.Clients.FirstName;
        _objAdd.LastName = item.Clients.LastName;
        if (item.Clients.DateBirth != null)
            _objAdd.Dob = item.Clients.DateBirth.Value;
        _objAdd.Gender = item.ClientDemographics.Gender;


        _obj.Add(_objAdd);
    }


    return View(_obj);
}

Move the declaration of _obj outside the foreach loop.
The lexical scope of variable _obj is inside the scope defined by the braces {}. So, the variable _obj is not accessible outside the loop. Once you move the variable outside, it is accessible at the Index method level.

public ActionResult Index()
{

    var Get_ClientInfor = example();

    var _obj = new List<C>();
    foreach (var item in Get_ClientInfor)
    {
        var _objAdd = new C();
        _objAdd.FirstName = item.Clients.FirstName;
        _objAdd.LastName = item.Clients.LastName;
        if (item.Clients.DateBirth != null)
        {
            _objAdd.Dob = item.Clients.DateBirth.Value;
        }
        _objAdd.Gender = item.ClientDemographics.Gender;

        _obj.Add(_objAdd);
    }
    return View(_obj);//error ===>>
}
