简易C#动态加载dll(实现插件化)

首页 / 正文

可以通过该方法来实现程序插件化。

假设A,B两个类，A类为宿主，B类为插件需要加载到A类中：

 class Program
{
    public interface IHellow
    {
        void Hellow();
    }

    static void Main(string[] args)
    {
        Assembly ass = Assembly.LoadFrom("D:/xx.dll");
        var wormMain = ass.GetTypes().FirstOrDefault(m => m.GetInterface(typeof(IHellow).Name) != null);
        var tmpObj = (IHellow)Activator.CreateInstance(wormMain);

        tmpObj.Hellow();

        Console.Read();
    }
}

namespace ClassLibrary1
{
    public class WormMain : IHellow
    {
        public void Hellow()
        {
            Console.WriteLine("Test Ok");
        }
    }
}

需要引用一下A类的项目文件，以得到接口。

如果是连同依赖项一起被载入，应该调用Assembly.LoadFrom

A类输出结果:

"Test Ok"
