如何获得程序集的命名空间？

using System;
using System.Reflection;

public class Program
{
    public static void Main()
    {
        Assembly assembly = Assembly.LoadFrom("path_to_assembly.dll");
        Type[] types = assembly.GetTypes();

        foreach (Type type in types)
        {
            Console.WriteLine("命名空间：" + type.Namespace);
        }
    }
}
