Interface

public interface InterfaceBase
{
    public string Name { get; set; }
    public void DoSomething();
}

Class1

public class Student : InterfaceBase
{
    string name;

    public string Name { get { return name; } set => this.name = value; }

    public void DoSomething()
    {
        int i = 88;
        Console.WriteLine("Write homework.");
    }
}
class Worker : InterfaceBase
{
    public string Name { get => throw new NotImplementedException(); set => throw new NotImplementedException(); }

    public void DoSomething()
    {
        Console.WriteLine("Working.");
    }
}
class Cat
{
    string name;
}

Class2

public class Teacher : InterfaceBase
{
    string name;

    public string Name { get { return name; } set => this.name = value; }

    public void DoSomething()
    {
        Console.WriteLine("Teaching Math.");
    }
}

TestClass

string dllPath = System.Environment.CurrentDirectory;
//加载路径下的文件
string[] files = Directory.GetFiles(dllPath);
foreach(string file in files)
{
    if (!file.Contains(".dll"))//过滤
        continue;
    Assembly ass = Assembly.LoadFile(file);
    Type[] types = ass.GetTypes();
    object obj = null;
    foreach (Type t in types)
    {
        // 判断类是否实现接口
        if(typeof(InterfaceBase).IsAssignableFrom(t))
        {
            obj = ass.CreateInstance(t.FullName, true);
        }
        if (obj is InterfaceBase)//判断的另一种形式
        {
            InterfaceBase ib = obj as InterfaceBase;
            ib.DoSomething();
        }
    }
}
