c＃ 控制台怎么调用Dll，如我的Dll里有命名空间a1，类名a2，公有的静态的无返回值的 方法a3

Answer 1

namespace a1
{
    public class a2
    {
        public static void a3()
        {
            Console.WriteLine("hello");
        }
    }
}

using a1;//先要引用dll再using
namespace ConsoleApplication12
{
    class Program
    {
        static void Main(string[] args)
        {
            a2.a3();
            Console.ReadLine();
        }
    }
}
