获取泛型抽象类的默认构造函数

using System;
using System.Reflection;

public abstract class MyGenericAbstractClass<T>

    public MyGenericAbstractClass()
    {
        Console.WriteLine("Default constructor of MyGenericAbstractClass");
    }
}

public class Program
{
    public static void Main()
    {
        Type genericType = typeof(MyGenericAbstractClass<>);
        Type[] typeArgs = { typeof(string) }; // 泛型参数类型
        Type constructedType = genericType.MakeGenericType(typeArgs); // 构造泛型类型

        ConstructorInfo constructor = constructedType.GetConstructor(Type.EmptyTypes);
        if (constructor != null)
        {
            object instance = constructor.Invoke(null);
            Console.WriteLine("Created instance of {0}", instance.GetType());
        }
        else
        {
