MVP 模式是否应该这样修改2？

最后，当然是界面实现。

这时业务操作对象及客户资料数据接口已定义好后，你可使用WebForm 、WinForm 或者WPF 等实现界面编辑，我这里使用的是WinForm 实现。

客户资料编辑界面

下面编辑界面的后台代码

using System.Text;
using System.Windows.Forms;

namespace HenXiao.WinUI

    public partial class FrmCustomerEdit : Form,ICustomer

        HxCustomerHelper helper = null;

        public FrmCustomerEdit()
        {
            InitializeComponent();
            helper = new HxCustomerHelper(this);
        }

        #region ICustomer 成员

        }

        public string CstNo

                    return DateTime.MinValue;
                else
                    return Convert.ToDateTime(this.dtpCstBirthday.Text);
            }
            set
            {
                this.dtpCstBirthday.Text = value.ToString();
            }
        }

        public string CstTele
        {
            get
            {
                return this.txtCstTele.Text;
            }
            set

                this.txtCstTele.Text = value;
            }
        }

        public string CstZip
        {
            get
            {
                return this.txtCstZip.Text;
            }
            set
            {
                this.txtCstZip.Text = value;
            }
        }

        public string CstAddr
        {
            get
            {
               return this.txtAddr.Text;
            }
            set
            {
                this.txtAddr.Text = value;
            }
        }

        public string CstExp
        {
            get
            {
                return this.txtCstExp.Text;
            }
            set
            {
                this.txtCstExp.Text = value;
            }
        }

        public string CstSex
        {
            get
            {
                return this.cmbCstSex.Text;
            }
            set
            {
                this.cmbCstSex.Text = value;
            }
        }

        public string CstCertType
        {
            get
            {
                return this.cmbCstCertType.Text;
            }
            set
            {
                this.cmbCstCertType.Text = value;
            }
        }

        public string CstCertNo
        {
            get
            {
                return this.txtCstCertNo.Text;
            }
            set
            {
                this.txtCstCertNo.Text = value;
            }
        }

        public string CstEmail
        {
            get
            {
                return this.txtCstEmail.Text;
            }
            set
            {
                this.txtCstEmail.Text = value;
            }
        }

        public string CstCompany
        {
            get
            {
                return this.txtCstCompany.Text;
            }
            set
            {
                this.txtCstCompany.Text = value;
            }
        }

        #endregion

        private void FrmCustomer_Load(object sender, EventArgs e)
        {
            this.cmbCstCertType.Items.Add("身份证");
            this.cmbCstCertType.Items.Add("护照");
            this.cmbCstCertType.Items.Add("军官证");

            this.cmbCstSex.Items.Add("男");
            this.cmbCstSex.Items.Add("女");

            this.helper.DataLoad();
        }

        private void btnOK_Click(object sender, EventArgs e)
        {
            if (this.helper.Save())
            {
                MessageBox.Show("保存成功。", "保存成功", MessageBoxButtons.OK, MessageBoxIcon.Information);
                this.Close();
            }
            else
                MessageBox.Show(this.helper.ErrorMessage,"保存出错",MessageBoxButtons.OK,MessageBoxIcon.Error);
        }

        private void btnCancel_Click(object sender, EventArgs e)
        {
            this.Close();
        }
    }
}

这样，这个事例基本完成，编辑界面后台基本无任何业务逻辑。

有更好方法实现业务逻辑与界面分隔，欢迎指教。
