I'm attempting to filter results from a database using Entity Framework CTP5. Here is my current method.

IQueryable<Form> Forms = DataContext.CreateFormContext().Forms;
foreach(string header in Headers) {
    Forms = Forms.Where(f => f.GetType()
                              .GetProperty(header)
                              .GetValue(f, null)
                              .ToString()
                              .IndexOf(filter,
                                  StringComparison.InvariantCultureIgnoreCase) >= 0);
}

However, I found that GetValue doesn't work using Entity Framework. It does when the type if IEnumerable<> but not IQueryable<>

Is there an alternative I can use to produce the same effect?
