How to define an Anonymous type lambda parameter in Linq Expression

  public static Type CreateNewType(List<PropertyInfo> props)
        {
            AssemblyName asmName =  typeof(Program).Assembly.GetName();
            AssemblyBuilder dynamicAssembly = AssemblyBuilder
                .DefineDynamicAssembly(asmName, AssemblyBuilderAccess.Run);
            ModuleBuilder dynamicModule = dynamicAssembly.DefineDynamicModule("MyAsm");
            TypeBuilder dynamicAnonymousType = dynamicModule
                .DefineType("MyType", TypeAttributes.Public);

            foreach (var p in props)
            {
                dynamicAnonymousType.DefineField(p.Name, p.PropertyType, FieldAttributes.Public);
            }
            return dynamicAnonymousType.CreateType();
        }
