设计模式之C#实现(二)---Builder[8]

              public string showselfparts(){

                     string strresult = string.empty;

                     int i = 1;

                     foreach(string strtmp in this.m_parts.values){

                            strresult +="part"+i.tostring()+":\t"+strtmp+"\n";

                            i++;

                     }

                     return strresult;

              }

       }

}

客户端的代码片断如下：

director director = new director();
