Answer 1

I found another nice code snippet here, and I have slightly modified it for 'DisplayName' purpose

    public static string GetDisplayName(Expression> expression)
    {
        var attribute = Attribute.GetCustomAttribute(((MemberExpression)expression.Body).Member, typeof(DisplayNameAttribute)) as DisplayNameAttribute;

        if (attribute == null)
        {
            throw new ArgumentException($"Expression '{expression}' doesn't have DisplayAttribute");
        }

        return attribute.DisplayName;
    }

And usages

GetDisplayName(i => i.PropertyName)
