Build string method using complex type Entity Framework ASP.NET C#

Question

I had to use Entity Framework to equip an advanced search to my website application.

The model is generated from the database and has own entities but has some complex s

Answer 1

This is your problem, read up on c# anonymous types

q => new
    {
        q.cFName,
        q.cLName,
        q.cSex,
        q.aId,
        q.cId,
        q.stars
   });

Remove new, and if needed create a new type to hold this, adding back in new with

new MyNewType {.. };

THen use this type in your method

Answer 2

To do this you need to build an external model with an IQueryable public method to returning data as IQueryable as following:

 public class customerComplex
{
    public string cFName { get; set; }
    public string cLName { get; set; }
    public int cSex { get; set; }
    public string aId { get; set; }
    public string cId { get; set; }
    public int stars { get; set; }

    public IQueryable<customerComplex> GetValues()
    {
        return new List<customerComplex>().AsQueryable();
    }
}

Indeed, I don't know what the data-types are exactly of your data model, but we assume I guess right. know you can use the custom model customerComplex to get select data from your linq query as following
:

var queryFinal = query.Select(q => new customerComplex
            {
                cId = q.cId,
                cFName = q.cFName,
                cLName = q.cLName,
                cSex = q.cSex,
                aId = q.aId,
                stars = q.stars
            }).ToList();

At last, you need to send the queryFinal to a function that you mentioned it. we assume you function is Customer_List(?). I defined this function in another class as following:

public string Customer_List(IEnumerable<customerComplex> query)
{
    string post = "";
    if(query.Count() > 0)
    {
        foreach (var item in query)
        {
            string name = item.cFName + " " + item.cLName;
            post += "<p>" + name + "</p>";
        }
    }
    return post;
}

Now, You can call Customer_List() and sent the queryFinal as folloing code:

string post = cls.Customer_List(queryFinal.AsEnumerable());
