使用动态生成的Lambda作为Linq order的输入

我想以编程方式创建Linq order子句。因此，我尝试动态创建Lambdas并将它们用作OrderBy子句的输入，但它不起作用。不确定order的实际输入是什么

我在这里错过了什么?

    static void Main(string[] args)
    {
        List<Person> people = new List<Person>();
        people.Add(new Person { Age = 10, Name = "D" });
        people.Add(new Person { Age = 20, Name = "C" });
        people.Add(new Person { Age = 30, Name = "B" });
        people.Add(new Person { Age = 40, Name = "A" });
        var paramExpr = Expression.Parameter(typeof(Person), "p");
        var prop = Expression.Property(paramExpr, "Name");
        var lambdaExpr = Expression.Lambda(prop, new List<ParameterExpression>() { paramExpr });
        Console.WriteLine(lambdaExpr); //Outputs p => p.Name

        var sortedPeople = people.OrderBy(lambdaExpr.Compile()); //This doesn't work.
        //var sortedPeople = people.OrderBy(p => p.Name); //This works
        foreach (var person in sortedPeople)
        {
            Console.WriteLine(String.Format("{0} - {1}", person.Name, person.Age));
        }
        Console.ReadKey();
    }

var lambdaExpr = Expression.Lambda<Func<Person, object>>(prop, new List<ParameterExpression>() { paramExpr });
