GetProperty and GetValue - Reflection [duplicate]

This question already has an answer here:

• PropertyInfo GetValue() Object does not match target type 4 answers

I'm getting error during GetValue

"Object does not match target type."

My aim is to pass some strings like:

• interface names, class names, property names

for ViewComponent that could use different repositories in many views.

ViewComponent - my test code for reflection

I'm getting error here --> test1

public class DataFilterAutocompleteViewComponent : ViewComponent
    {
        public Assembly Assembly
        {
            get
            {
                return Assembly.GetExecutingAssembly();
            }
        }

        public IViewComponentResult Invoke(string blablabla)
        {
            Type interfaceType = AssemblyHelper.GetTypeByClassName(Assembly, Interfaces.Repo.EFProductRepository).GetInterface(Interfaces.IProductRepository);
            Type repoType = AssemblyHelper.GetTypeByClassName(Assembly, Interfaces.Repo.EFProductRepository);
            var test = interfaceType.GetProperty("testProducts"); //.GetValue(new List<Product>())
            var test1 = test.GetValue(new List<Product>());
            return View(blablabla);
        }
    }

AssemblyHelper

public static class AssemblyHelper
{
    public static IEnumerable<Type> GetLoadableTypes(Assembly assembly)
    {
        if (assembly == null) throw new ArgumentNullException(nameof(assembly));

        try
        {
            return assembly.GetTypes();
        }
        catch (ReflectionTypeLoadException e)
        {
            return e.Types.Where(t => t != null);
        }
    }

    public static Type GetTypeByClassName(Assembly assembly, string className)
    {
        if (assembly == null) throw new ArgumentNullException(nameof(assembly));

        return AssemblyHelper.GetLoadableTypes(assembly).Where(a => a.Name == className).FirstOrDefault();
    }

    public static string GetAssemblyName()
    {
        return Assembly.GetExecutingAssembly().GetName().Name;
    }

    public static Object GetConstructorByClassName(Assembly assembly, string className)
    {
        if (assembly == null) throw new ArgumentNullException(nameof(assembly));
        if (className == null) throw new ArgumentNullException("Cant find class: " + className);

        Type type = Type.GetType(AssemblyHelper.GetTypeByClassName(assembly, className) + ", " + AssemblyHelper.GetAssemblyName());
        return Activator.CreateInstance(type);
    }
}

Interface

public interface IProductRepository
{
    IQueryable<Product> Products { get; }
    List<Product> testProducts { get; }
}

Question: I don't understand why I'm getting such an error. I'm passing a correct type for this property.
