How can pass a column name as a parameter for dynamic search in entity-framework

Question

My requirement is to pass column name along with search data for dynamically searchning from db using linq query in entityframework.

[HttpGet]
public ActionResult Index(string Search, string Column)
{
    if (!String.IsNullOrEmpty(Search))
    {
        List<Employee> result = new List<Employee>();
        result = db.Employees.ToList();
        result = result.Where(x => x.Column.ToLower().Contains(Search.ToLower())).ToList();
        return View(result);      
    }
    else
    {
       return View(db.Employees.ToList());  
    }          

}

I think you are looking something like DLinq . Use the DLinq nuget package

var result=  db.Employees.Where(Column+".Contains"+ "(\""+ Search.ToLower() + "\")").ToList();

The Column parameter must match with the name of one string property in your Employee entity. I suggest use a try-catch in case you pass a wrong name.
