c# - reflection on List and printing values

Question

I wrote a method that accepts a generic parameter and then it prints its properties. I use it to test my web service. It's working but I want to add some features that I don't know how to implement. I want to print values of lists, because now it just writes System.Collection.Generic.List1 which is expected.

Here is my code so far, this is working for basic types (int, double etc.):

static void printReturnedProperties<T>(T Object)
{ 
   PropertyInfo[] propertyInfos = null;
   propertyInfos = Object.GetType().GetProperties();

   foreach (var item in propertyInfos)
      Console.WriteLine(item.Name + ": " + item.GetValue(Object).ToString());
}

You could do something like this:

    static void printReturnedProperties(Object o)
    {
        PropertyInfo[] propertyInfos = null;
        propertyInfos = o.GetType().GetProperties();



        foreach (var item in propertyInfos)
        {
            var prop = item.GetValue(o);

            if(prop == null)
            {
                Console.WriteLine(item.Name + ": NULL");
            }
            else
            {
                Console.WriteLine(item.Name + ": " + prop.ToString());
            }


            if (prop is IEnumerable)
            {
                foreach (var listitem in prop as IEnumerable)
                {
                    Console.WriteLine("Item: " + listitem.ToString());
                }
            }
        }


    }

It will then enumerate through any IEnumerable and print out the individual values (I'm printing them one per line, but obviously, you can do different.)
