public interface ILinkGeneratedString
{
    string LinkGeneratedString { get; }
}

//an extension method used to convert property value to a string
public static class UrlValuesExtensions
{
    public static object ToUrlValues(this object o)
    {
        if (o == null || o is RouteValueDictionary) return o;
        var values = new Dictionary<string, string>();
        //only public readable properties are read
        //this excludes the indexers (a special type of property) as well
        foreach(var prop in o.GetType().GetProperties()
                                       .Where(p => p.CanRead && p.GetIndexParameters().Length == 0))
        {
            var pv = prop.GetValue(o);
            var value = pv == null ? "" :
                        pv is ILinkGeneratedString ls ? ls.LinkGeneratedString : pv.ToString();
            values[prop.Name] = value;
        }
        return values;
    }
}

//the custom UrlHelper
public class CustomUrlHelper : UrlHelper
{
    public CustomUrlHelper(ActionContext actionContext) : base(actionContext)
    {
    }
    public override string Action(UrlActionContext actionContext)
    {            
        //apply the conversion here
        actionContext.Values = actionContext?.Values?.ToUrlValues();
        return base.Action(actionContext);
    }
}

//we need a custom IUrlHelperFactory as well
public class CustomUrlHelperFactory : IUrlHelperFactory
{
    public IUrlHelper GetUrlHelper(ActionContext context)
    {
        return new CustomUrlHelper(context);
    }
}
