一、运行效果

二、实现过程

①、房间管理

新增房间

string sql = string.Format(@"insert into RoomTable(RoomID, Floor, TypeID, StateID)values('{0}','{1}','{2}','{3}')", tbFangHao.Text, tbLouCeng.Text, cbLeiXing.SelectedValue.ToString(), cbZhuangTai.SelectedValue.ToString());
if (db.ExecuteSQLCommand(sql) > 0)
{string aac = string.Format("{0}房间新增成功！", tbFangHao.Text);MessageBox.Show(aac);
}

激活房卡

string sql = string.Format(@"insert into RoomIDCard(RoomID, RoomCard)values('{0}','{1}')", FangHao, tbFangKa.Text);
int a = db.ExecuteSQLCommand(sql);
if (a > 0)
{string aaac = string.Format("激活成功！房号为：{0}，房卡为：{1}", FangHao, tbFangKa.Text);MessageBox.Show(aaac);
}
else
{string aaac = string.Format("{0}房卡激活失败！", FangHao);MessageBox.Show(aaac);
}

②、房客管理

新增房客

string gender = "男";
if (rbNv.Checked)
{gender = "女";
}
//向顾客表中插入数据
string sql = string.Format(@"insert into CustomerTable( Name, CarID, Phone, Balance, Type, Sex, Age)values('{0}','{1}','{2}','{3}','{4}','{5}','{6}')", tbXingMing.Text, tbShenFenZheng.Text, tbDianHua.Text, tbJinE.Text, cbLeiXing.SelectedValue, gender, tbNianLing.Text);
if (db.ExecuteSQLCommand(sql) > 0)
{string sj = DateTime.Now.ToString();//新增到充值记录表try{sql = string.Format(@"insert into  CustomerRecharge(RechargeTime, RechargeAmount, RechargeIDCardNumber, Gifts)values('{0}','{1}','{2}','{3}')", sj, tbJinE.Text, tbShenFenZheng.Text, "新开会员");if (db.ExecuteSQLCommand(sql) == 0){MessageBox.Show("新增到充值记录表中失败！");}}catch (Exception er){MessageBox.Show(er.Message);}finally{db.CloseConnection();}string aacc = string.Format("{0}恭喜您成为{1}", tbXingMing.Text, cbLeiXing.Text);MessageBox.Show(aacc);this.Close();
}
else
{MessageBox.Show("添加失败！");
}

新增房客折扣类型

string sql = string.Format(@"insert into CustomerTypeTable(Grade, Discount)values('{0}','{1}')", tbLeiXing.Text, tbZheKou.Text);
if (db.ExecuteSQLCommand(sql) > 0)
{MessageBox.Show("添加成功！");
}

③、开房管理

预定房间

int zhi = 0;
for (int i = 0; i < lvYiXuang.Items.Count; i++)
{try{string sql = string.Format(@"insert into PredeterminedTable(reservationNumber, Name, Phone, RoomID, RoomType, PreconditioningTime, PreDepartureTime, Operator, Price, Type)values('{0}','{1}','{2}','{3}','{4}','{5}','{6}','{7}','{8}','{9}')", tbDingDanHao.Text, txtXingMing.Text, txtDianHua.Text, lvYiXuang.Items[i].SubItems[0].Text, lvYiXuang.Items[i].SubItems[1].Text, tpRuZhu.Text, tpYuLi.Text, "1", lvYiXuang.Items[i].SubItems[2].Text, "预定中");if (db.ExecuteSQLCommand(sql) > 0){zhi++;}}catch (Exception ee){MessageBox.Show(ee.Message);}finally{db.CloseConnection();}
}MessageBox.Show("成功预定" + zhi + "房！");
this.Close();

④、员工管理

新增员工

ring sql = string.Format(@"insert into UserTable(UserName, PassWord, CarID, EmployeeName, Jurisdiction)values('{0}','{1}','{2}','{3}','{4}')", txtZhangHao.Text, txtMiMa2.Text, txtShengFenZheng.Text, txtXingMing.Text, cbQuanXian.Text);

}

⑤、商品操作

新增商品

string sql = string.Format(@"insert into Commodity(Name, Company, Number, BuyingPrice, RetailPrice, Type)
values('{0}','{1}','{2}','{3}','{4}','{5}')", tbMingCheng.Text, tbDanWei.Text, tbShuLiang.Text, tbJinHuoJia.Text, tbLingShouJia.Text, cbLeiXing.SelectedValue);
if (db.ExecuteSQLCommand(sql) > 0)
{MessageBox.Show("新增商品成功！");this.Close();
}

商品结账

if (lvGouWuChe.Items.Count > 0)
{string sql;for (int i = 0; i < lvGouWuChe.Items.Count; i++){try{sql = string.Format(@"update [dbo].[Commodity] set  Number-={0}where Name = '{1}'", Convert.ToInt32(lvGouWuChe.Items[i].SubItems[3].Text), lvGouWuChe.Items[i].SubItems[0].Text);if (db.ExecuteSQLCommand(sql) == 0){MessageBox.Show("商品数量修改失败！");}}catch (Exception ee){MessageBox.Show(ee.Message);}finally{db.CloseConnection();}}sql = string.Format(@"insert into MerchandiseOrderTable(OrderTable, CollectMoney, PaymentMethod)values('{0}','{1}','{2}')", DateTime.Now.ToString(), tbHeJi.Text, cbFuKuangFangShi.Text);if (db.ExecuteSQLCommand(sql) > 0){MessageBox.Show("购买成功！");tbHeJi.Text = "";tbShiShou.Text = "";tbZhaoLing.Text = "";lvGouWuChe.Items.Clear();}
}
else
{MessageBox.Show("请选择商品！");
}

⑥、数据库操作类

数据库操作类包括执行SQL语句，查询返回单个值/表格等操作。

using System;
using System.Data;
using System.Data.SqlClient;namespace S1Hotel
{class DBHelper{//创建数据库连接private static string str = @"Data Source=.;Initial Catalog=S1Hotel;Integrated Security=True";private SqlConnection con = new SqlConnection(str);/// <summary>/// 查询多个值的方法/// </summary>/// <param name="str"></param>/// <param name="sql"></param>/// <returns></returns>public SqlDataReader SelectDataReader(string sql){con.Open();SqlCommand com = new SqlCommand(sql, con);return com.ExecuteReader(CommandBehavior.CloseConnection);//返回SqlDataReader关闭SqlConnection对象连接}/// <summary>/// 备用关闭数据库/// </summary>public void CloseConnection(){con.Close();}/// <summary>/// 增删改/// </summary>/// <param name="sql">SQL语句</param>/// <returns></returns>public int ExecuteSQLCommand(string sql){con.Open();SqlCommand com = new SqlCommand(sql, con);int a = com.ExecuteNonQuery();con.Close();return a;}/// <summary>/// 查询一张表的数据/// </summary>/// <param name="sql">SQL语句</param>/// <param name="biaoMing"></param>/// <returns></returns>public DataSet GetDataSet(string sql, string biaoMing){SqlDataAdapter da = new SqlDataAdapter(sql, con);DataSet ds = new DataSet();da.Fill(ds, biaoMing);return ds;}/// <summary>/// 查询单个值并返回int类型/// </summary>/// <param name="sql"></param>/// <returns></returns>public int GetSingleIntValue(string sql){con.Open();SqlCommand com = new SqlCommand(sql, con);int a = 0;var t = com.ExecuteScalar();//当com.ExecuteScalar()等于空时就返回0；if (t == DBNull.Value || t == null){}else{a = (int)com.ExecuteScalar();}con.Close();return a;}/// <summary>/// 查询单个值并返回double类型/// </summary>/// <param name="sql"></param>/// <returns></returns>public double GetSingleDoubleValue(string sql){con.Open();SqlCommand com = new SqlCommand(sql, con);double a = 0;var t = com.ExecuteScalar();//当com.ExecuteScalar()等于空时就返回0；if (t == DBNull.Value || t == null){}else{a = Convert.ToDouble(com.ExecuteScalar());}con.Close();return a;&nbnbsp;      }/// <summary>/// 计算时间重叠/// </summary>/// <param name="a"></param>/// <param name="b"></param>/// <param name="x"></param>/// <param name="y"></param>/// <returns></returns>public bool CalcTimeOverlap(DateTime a, DateTime b, DateTime x, DateTime y){//时间无重叠             return b >= x && y >= a;/*if ((b < x) || (y < a))return false;return true;*/}}
