Hi !
From what i can see, there are two types of materials in the shader library :
Predefined Materials
and
Predefined Surface Shaders

for an example of how to load a Predefined Surface Shader (a shader that uses a .fx file) follow this link to an example (there is also a download link to an example) : shader example

If you on the other hand want to assign a Predefined Material, then you only have to assign the corresponding EngVar. Here's an example :

Code:
using System;
using System.Collections.Generic;
using AcknexWrapper;

namespace ShaderTest
{
    class Program
    {
        static void Main(string[] args)
        {
            EngFun.engine_open(null, null);

            Scheduler.StartScheduler(MyMainMethod);
        }

        private static IEnumerable<ScheduleMethod> MyMainMethod()
        {
            // load an empty level
            EngFun.level_load(null);

            // create a cube (_CUBE.mdl is a predefined model - CUBE_MDL in lite-c)
            ENTITY cube =
                ENTITY.ent_create(
                    "_CUBE.mdl",
                    new Vector(60, -20, 0),
                    CubeMethod);

            yield break;
        }

        private static IEnumerable<ScheduleMethod> CubeMethod(IntPtr p)
        {
            ENTITY cube =
                ENTITY.createFromPointer(p);

            // now assign the standard metal material
            cube.material =
                EngVar.mtl_metal;

            // change the ambient vector of the standard metal material
            EngVar.mtl_metal.ambient_red = 255;

            while (true)
            {
                // rotate the cube
                cube.pan += 2 * EngVar.time_step;
                cube.tilt += 1.5 * EngVar.time_step;

                // wait one frame
                yield return 1;
            }
        }
    }
}
