Create a list of strongly typed variable names using Expression

I have a class:

public class Student
{
    [JsonProperty("name")]
    public string Name { get; set; }

    [JsonProperty("age")]
    public int Age { get; set; }

    [JsonProperty("country")]
    public string Country { get; set; }
}

And I have a method:

public static List<string> PrintPropertyNames<T>(params Expression<Func<T, object>>[] properties)
{
    var list = new List<string>();

    foreach (var p in properties)
    {
        if (p.Body is MemberExpression)
        {
            var e = (MemberExpression)p.Body;
            list.Add(((JsonPropertyAttribute)e.Member.GetCustomAttribute(typeof(JsonPropertyAttribute))).PropertyName);
        }
        else
        {
            var e = (MemberExpression)((UnaryExpression)p.Body).Operand;
            list.Add(((JsonPropertyAttribute)e.Member.GetCustomAttribute(typeof(JsonPropertyAttribute))).PropertyName);
        }
    }

    return list;
}

Which I call like this:

Console.WriteLine(string.Join(" ", PrintPropertyNames<Student>(x => x.Age, x => x.Country)));

Now, I want to modify my method definition to take only one parameter, but I can't figure out how to do it.

I tried doing something like this:

public static List<string> PrintPropertyNames2<T>(Expression<Func<T, object>>[] properties)

Which I call like this:

Console.WriteLine(string.Join(" ", PrintPropertyNames2<Student>(new Expression<Func<Student, object>>[] { x => x.Age, x => x.Country })));

I tried simplifying it to:

Console.WriteLine(string.Join(" ", PrintPropertyNames2<Student>(new [] { x => x.Age, x => x.Country })));

But the compiler couldn't find the best suitable type. So I have to explicitly write the type, which looks ugly and not what I really want anyways. I need it generic.

What I want to do in the final version is the following:

Console.WriteLine(string.Join(" ", PrintPropertyNames<Student>(x => x.Age && x.Country && x.Name))); (output should be - age country name)

I'm not sure if that's possible, but I want to put all my properties inside a single expression and obtain their json attribute value at once.
