How to get the Value in [Display(Name="")] attribute in Controller for any property using EF6

This should work:

MemberInfo property = typeof(ABC).GetProperty(s); 
var dd = property.GetCustomAttribute(typeof(DisplayAttribute)) as DisplayAttribute;
if(dd != null)
{
  var name = dd.Name;
}

You can use it:

MemberInfo property = typeof(ABC).GetProperty(s); 
var name = property.GetCustomAttribute<DisplayAttribute>()?.Name;
