how to return each foreach -loop element through return statement

public Circle3D GetSphereCircle(BaseLibrary.VIEWCODE viewCode)
{
          
    List<vec3> VectorList = new List<vec3>();
    Vec3 vec = new Vec3(0, 0, 0);

     -----
   

    foreach (Vec3 vector in VectorList)
    {
        refPlane = new Plane3D(new Plane3(centPt, vector), false);
        circle = new Circle3D(new Circle3(centPt, _local_data._radius), refPlane, false);
    }
    return circle;
}
