 public class Product
    {
        public IList<string> parts = new List<string>();
        public void Add(string part)
        {
            parts.Add(part);
        }
        public IList<string>  Show()
        {
            return parts;
            
        }
    }

abstract class Builder
    {
      public abstract void CreatStyle();

        public override void CreatStyle()
        {
            car.Add("F1样式");
        }

        public override void CreatWheel()
        {
            car.Add("沙漠车轮");
        }

        public override void CreatEngine()
        {
            car.Add("顶级发动机");
        }

        public override void CreatColor()
        {
            car.Add("红白相间");
        }

        public override Product Getresult()
        {
            return car;
        }
    }
 class Director
    {
        public void Construct(Builder c)
        {
            c.CreatColor();
            c.CreatEngine();
            c.CreatStyle();
            c.CreatWheel();
        }
    }
public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        private void button1_Click(object sender, EventArgs e)
        {
            Director director = new Director();
            Cbuilder racing = new Cbuilder();
            director.Construct(racing);
            Product p1 = racing.Getresult();
            
            p1.Show();
            foreach (string part in p1.parts)
            {
                textbox1.Text = part;

            }
        }
    }

我想在textbox里显示结果，该怎么弄呢. 上面写的foreach 不行.. 求教。

大牛都吃饭去了吗...

[phil999]

textbox1.Text += part;

[Quote=引用 2 楼 phil999 的回复:]
textbox1.Text += part;

还是不行 .. show()方法应该不对 不知道怎么改啊...

用个for循环试试
