Compiling assembly with CodeDomProvider --> FindAll Method with predicate

Question

Hi, I'm trying to compile a dynamic assembly from code with the CodeDomProvider which contains a FindAll method on a list with Predicates. example: using System; using System.Linq; using System.Collections; using System.Collections.Generic; using ET.Common; using ET.Deap.Common; using ET.Deap.Common.Model; public static class SearchAssembly { public static IList RunFilter(IList list) { return list.Cast().ToList().FindAll(x => (x.Id == 30) && (x.TestDataItems.ToList().Exists(y => y.Status == Status.CheckedTrue))); } } this will always give me a compiler error "CS1525" "Invalid expression term '>'" why isnt it able to recognize my predicate? what would be the easiest solution?
