C#获取具有特定属性参数的所有类的列表[重复]

我试图得到一个所有类的列表,其中包含一个特定的属性和该属性的枚举参数。

查看下面的示例。我实现了如何获取具有属性的所有类 GenericConfig ,但是,如何对参数进行过滤?

namespace ConsoleApp1
{
    internal class Program
    {
        private static void Main(string[] args)
        {
            // get me all classes with Attriubute GenericConfigAttribute and Parameter Type1
            var type1Types =
                    from type in Assembly.GetExecutingAssembly().GetTypes()
                    where type.IsDefined(typeof(GenericConfigAttribute), false)
                    select type;

            Console.WriteLine(type1Types);
        }
    }

    public enum GenericConfigType
    {
        Type1,
        Type2
    }

    // program should return this class
    [GenericConfig(GenericConfigType.Type1)]
    public class Type1Implementation
    {
    }

    // program should not return this class
    [GenericConfig(GenericConfigType.Type2)]
    public class Type2Implementation
    {
    }

    [AttributeUsage(AttributeTargets.Class, AllowMultiple = true)]
    public class GenericConfigAttribute : Attribute
    {
        public GenericConfigType MyEnum;

        public GenericConfigAttribute(GenericConfigType myEnum)
        {
            MyEnum = myEnum;
        }
    }
}
