Getting StackOverflowException when setting property

public List<Empleado> ListarEmpleados()
    {
        List<Empleado> returnList = new List<Empleado>();
        var lista = from u in DB.tabEmpleado
                    select new
                    {
                        u.idEmpleado,
                        u.idUsuario,
                        u.Nombre,
                        u.Apellidos,
                        u.Telefono1
                    };                           
        foreach (var e in lista)
        {
            Empleado empleado = new Empleado();
            empleado.idEmpleado = e.idEmpleado;
            empleado.idUsuario = e.idUsuario;
            empleado.nombre = e.Nombre;
            empleado.apellidos = e.Apellidos;
            empleado.telefono1 = e.Telefono1;
            returnList.Add(empleado);                
        }
        return returnList;
    }

This is a WCF service, when is called it returns StackOverflow error in the class definition, exactly in the Set property of idEmpleado.

Class definition is here.

[DataContract]
public class Empleado
{                
    private int _idEmpleado;
    [DataMember(IsRequired = false)]
    public int idEmpleado
    {
        get { return _idEmpleado; }
        set { idEmpleado = value; } ERROR
    }


    private int _idUsuario;
    [DataMember(IsRequired = false)]
    public int idUsuario
    {
        get { return _idUsuario; }
        set { idUsuario = value; }
    }

    private string _nombre;
    [DataMember(IsRequired = false)]
    public string nombre
    {
        get { return _nombre; }
        set { nombre = value; }
    }

    private string _apellidos;
    [DataMember(IsRequired = false)]
    public string apellidos
    {
        get { return _apellidos; }
        set { apellidos = value; }
    }

    private string _telefono1;
    [DataMember(IsRequired = false开发者_如何转开发)]
    public string telefono1
    {
        get { return _telefono1; }
        set { telefono1 = value; }
    }
}

}

Does anybody know where the error is?

Thanks in advance.

You are setting the value of the property by calling the property setter again, instead of directly setting its backing field. This causes an infinite recursion and a stack overflow as a result.

public int idEmpleado
{
    get { return _idEmpleado; }
    set { idEmpleado = value; } // SHOULD BE _idEmpleado = value
}
