How to pass anonymous types as parameters?

I think you should make a class for this anonymous type. That’d be the most sensible thing to do in my opinion. But if you really don’t want to, you could use dynamics:

public void LogEmployees (IEnumerable<dynamic> list)
{
    foreach (dynamic item in list)
    {
        string name = item.Name;
        int id = item.Id;
    }
}

Note that this is not strongly typed, so if, for example, Name changes to EmployeeName, you won’t know there’s a problem until runtime.
