【机房重构】-C#注册
【前文】
机房做到这里也是遇到了很多问题的，但是也正是在这个过程中，当然学会了怎么去解决问题这是很关键的，在查的过程中发现C#版的还是很少的，所以也是走了不少弯路，都能成为经历把。

敲注册的时候也是按照“七层”走下来的，下面是我的代码：
IDAL
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
namespace jfIDAL
{
public interface ICard
{
bool IsCardIDExist(int cardID);
int RegisterCard(jfEntity.Student student);
int RechargeCard(int cardID, decimal cardCash);
}
}
DAL
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Data;
using System.Data.SqlClient;
using System.Configuration;
using System.Net;
using jfIDAL;
namespace jfDAL
{
public class DCard:jfIDAL .ICard
{
#region 判断卡号是否存在
/// BLL
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Data;
using System.Data.SqlClient;
using System.Configuration;
using System.Net;
using jfIDAL;
namespace jfDAL
{
public class DCard:jfIDAL .ICard
{
#region 判断卡号是否存在
/// Facade
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Configuration ;
using System.Reflection;
namespace jfFactory
{
public class FaLogin
{
private static readonly string StrDB = System.Configuration.ConfigurationManager.AppSettings["DB"];
public static jfIDAL.ILogin CreateUser()
{
//通过反射实例化数据库相关类
string ClassName = StrDB + "." + "DLogin";
return (jfIDAL.ILogin)Assembly.Load(StrDB).CreateInstance(ClassName);
}
}
}
UI
private void button10_Click(object sender, EventArgs e)
{
if (txtcard.Text == "")
{
MessageBox.Show("卡号为空", "温馨提示");
txtcard.Focus();
}
else
{
if (txtname1.Text == "")
{
MessageBox.Show("学号为空", "温馨提示");
txtname1.Focus();
}
else
{
jfEntity.Student student = new jfEntity.Student ();
student.CardID = Convert.ToInt32(txtcard.Text);
student.StudentID = Convert.ToInt32(textBox32.Text);
student.StudentName = txtname1.Text.Trim();
student.StudentSex = cobStudentSex.SelectedIndex.ToString();
student.Grade = txtGrade1.Text.Trim();
student.Department = txtDepartment1.Text.Trim();
student.Class = txtClass1.Text.Trim();
student.Major = txtMajor.Text.Trim();
if (textBox30.Text == "")
{
student.Cash = 0;
}
else
{
student.Type = comboBox19.SelectedIndex.ToString();
student.Status = comboBox17.SelectedIndex.ToString();
jfFacade.FCard fcard = new FCard();
int result = fcard.RegisterCard(student);
if (result == 0)
{
MessageBox.Show("卡号已存在！", "温馨提示");
}
else
{
if (result == 1)
{
MessageBox.Show("注册成功！", "请继续");
}
else
{
MessageBox.Show("用户失败！", "请继续");
}
}【小结】
每每完成一个窗体，都是一次巨大的成长。
