如下:

using System;

namespace ConsoleApplication2
{
    public static class ClassSameAssembly
    {
        public static dynamic GetValues()
        {
            return new
            {
                Name = "Michael", Age = 20
            };
        }
    }

    internal class Program
    {
        private static void Main(string[] args)
        {
            var d = ClassSameAssembly.GetValues();
            Console.WriteLine("{0} is {1} years old", d.Name, d.Age);
        }
    }
}

返回:

Microsoft.CSharp.RuntimeBinder.RuntimeBinderException: 'object' does not contain a definition for 'Name'

使用 ExpandoObject:

public static dynamic GetValues()
{
    dynamic expando = new ExpandoObject();
    expando.Name = "Michael";
    expando.Age = 20;
    return expando;
}

如下:

 dynamic expando = new ExpandoObject()
 {
     { "Name", "Michael" },
     { "Age", 20 }
 };
 return expando;

可以使用[assembly: InternalsVisibleTo("YourAssemblyName")]
