1、基础框架准备工作
1.1 UI层建立wpf应用程序EmployeeListUI.xaml与EmployeeListEdit.xaml；Model层建立Employee类, DAL层建立EmployeeDAL类。
1.2 创建数据库表
USE [HRMSYSDB] GO /****** Object: Table [dbo].[T_Employee] Script Date: 05/15/2013 11:22:50 ******/ SET ANSI_NULLS ON GO SET QUOTED_IDENTIFIER ON GO CREATE TABLE [dbo].[T_Employee]( [Id] [uniqueidentifier] NOT NULL, [Number] [nvarchar](50) NOT NULL, [Name] [nvarchar](50) NOT NULL, [BirthDay] [datetime] NOT NULL, [InDate] [datetime] NOT NULL, [MarriageId] [uniqueidentifier] NOT NULL, [PartyStatusId] [uniqueidentifier] NOT NULL, [Nationality] [nvarchar](50) NOT NULL, [NativeAddr] [nvarchar](250) NOT NULL, [EducationId] [uniqueidentifier] NOT NULL, [Major] [nvarchar](50) NULL, [School] [nvarchar](50) NULL, [Address] [nvarchar](250) NOT NULL, [BaseSalary] [int] NOT NULL, [Email] [nvarchar](50) NULL, [IdNum] [nvarchar](50) NOT NULL, [TelNum] [nvarchar](50) NOT NULL, [EmergencyContact] [nvarchar](max) NULL, [DepartmentId] [uniqueidentifier] NOT NULL, [Position] [nvarchar](50) NOT NULL, [ContractStartDay] [datetime] NOT NULL, [ContractEndDay] [datetime] NOT NULL, [Resume] [nvarchar](max) NULL, [Remarks] [nvarchar](max) NULL, [IsStopped] [bit] NOT NULL, [GenderId] [uniqueidentifier] NOT NULL, [Photo] [image] NULL, CONSTRAINT [PK_T_Employee] PRIMARY KEY CLUSTERED ( [Id] ASC )WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY] ) ON [PRIMARY] TEXTIMAGE_ON [PRIMARY] GO EXEC sys.sp_addextendedproperty @name=N'MS_Description', @value=N'工号' , @level0type=N'SCHEMA',@level0name=N'dbo', @level1type=N'TABLE',@level1name=N'T_Employee', @level2type=N'COLUMN',@level2name=N'Number' GO EXEC sys.sp_addextendedproperty @name=N'MS_Description', @value=N'入职时间' , @level0type=N'SCHEMA',@level0name=N'dbo', @level1type=N'TABLE',@level1name=N'T_Employee', @level2type=N'COLUMN',@level2name=N'InDate' GO EXEC sys.sp_addextendedproperty @name=N'MS_Description', @value=N'婚姻状况' , @level0type=N'SCHEMA',@level0name=N'dbo', @level1type=N'TABLE',@level1name=N'T_Employee', @level2type=N'COLUMN',@level2name=N'MarriageId' GO EXEC sys.sp_addextendedproperty @name=N'MS_Description', @value=N'政治面貌' , @level0type=N'SCHEMA',@level0name=N'dbo', @level1type=N'TABLE',@level1name=N'T_Employee', @level2type=N'COLUMN',@level2name=N'PartyStatusId' GO EXEC sys.sp_addextendedproperty @name=N'MS_Description', @value=N'民族' , @level0type=N'SCHEMA',@level0name=N'dbo', @level1type=N'TABLE',@level1name=N'T_Employee', @level2type=N'COLUMN',@level2name=N'Nationality' GO EXEC sys.sp_addextendedproperty @name=N'MS_Description', @value=N'籍贯' , @level0type=N'SCHEMA',@level0name=N'dbo', @level1type=N'TABLE',@level1name=N'T_Employee', @level2type=N'COLUMN',@level2name=N'NativeAddr' GO EXEC sys.sp_addextendedproperty @name=N'MS_Description', @value=N'学历' , @level0type=N'SCHEMA',@level0name=N'dbo', @level1type=N'TABLE',@level1name=N'T_Employee', @level2type=N'COLUMN',@level2name=N'EducationId' GO EXEC sys.sp_addextendedproperty @name=N'MS_Description', @value=N'专业' , @level0type=N'SCHEMA',@level0name=N'dbo', @level1type=N'TABLE',@level1name=N'T_Employee', @level2type=N'COLUMN',@level2name=N'Major' GO EXEC sys.sp_addextendedproperty @name=N'MS_Description', @value=N'毕业院校' , @level0type=N'SCHEMA',@level0name=N'dbo', @level1type=N'TABLE',@level1name=N'T_Employee', @level2type=N'COLUMN',@level2name=N'School' GO EXEC sys.sp_addextendedproperty @name=N'MS_Description', @value=N'联系地址' , @level0type=N'SCHEMA',@level0name=N'dbo', @level1type=N'TABLE',@level1name=N'T_Employee', @level2type=N'COLUMN',@level2name=N'Address' GO EXEC sys.sp_addextendedproperty @name=N'MS_Description', @value=N'基本工资' , @level0type=N'SCHEMA',@level0name=N'dbo', @level1type=N'TABLE',@level1name=N'T_Employee', @level2type=N'COLUMN',@level2name=N'BaseSalary' GO EXEC sys.sp_addextendedproperty @name=N'MS_Description', @value=N'身份证号' , @level0type=N'SCHEMA',@level0name=N'dbo', @level1type=N'TABLE',@level1name=N'T_Employee', @level2type=N'COLUMN',@level2name=N'IdNum' GO EXEC sys.sp_addextendedproperty @name=N'MS_Description', @value=N'电话号码' , @level0type=N'SCHEMA',@level0name=N'dbo', @level1type=N'TABLE',@level1name=N'T_Employee', @level2type=N'COLUMN',@level2name=N'TelNum' GO EXEC sys.sp_addextendedproperty @name=N'MS_Description', @value=N'紧急联系人' , @level0type=N'SCHEMA',@level0name=N'dbo', @level1type=N'TABLE',@level1name=N'T_Employee', @level2type=N'COLUMN',@level2name=N'EmergencyContact' GO
2、Model层建立Employee类
与数据库表的字段对应，包括名称、类型，如数据字段为空者需要在类型后加?，因需要跨项目需要加public。
namespace HRMSys.Model { public class T_Employee { public System.Guid Id { get; set; } public System.String Number { get; set; } public System.String Name { get; set; } public System.DateTime BirthDay { get; set; } public System.DateTime InDate { get; set; } public System.Guid MarriageId { get; set; } public System.Guid PartyStatusId { get; set; } public System.String Nationality { get; set; } public System.String NativeAddr { get; set; } public System.Guid EducationId { get; set; } public System.String? Major { get; set; } public System.String? School { get; set; } public System.String Address { get; set; } public System.Int32 BaseSalary { get; set; } public System.String? Email { get; set; } public System.String IdNum { get; set; } public System.String TelNum { get; set; } public System.String? EmergencyContact { get; set; } public System.Guid DepartmentId { get; set; } public System.String Position { get; set; } public System.DateTime ContractStartDay { get; set; } public System.DateTime ContractEndDay { get; set; } public System.String? Resume { get; set; } public System.String? Remarks { get; set; } public System.Boolean IsStopped { get; set; } public System.Guid GenderId { get; set; } public System.Byte[] Photo { get; set; } } }
3、DAL层建立EmployeeDAL类
namespace HRMSys.DAL { public class EmployeeDAL { private Employee ToEmployee(DataRow row) { Employee employee = new Employee(); employee.Address = (string)row["Address"]; employee.BaseSalary = (int)row["BaseSalary"]; employee.BirthDay = (DateTime)row["BirthDay"]; employee.ContractEndDay = (DateTime)row["ContractEndDay"]; employee.ContractStartDay = (DateTime)row["ContractStartDay"]; employee.DepartmentId = (Guid)row["DepartmentId"]; employee.EducationId = (Guid)row["EducationId"]; employee.Email = (string)row["Email"]; employee.EmergencyContact = (string)SqlHelper.FromDbValue(row["EmergencyContact"]); employee.GenderId = (Guid)row["GenderId"]; employee.Id = (Guid)row["Id"]; employee.IdNum = (string)row["IdNum"]; employee.InDate = (DateTime)row["InDate"]; employee.Major = (string)row["Major"]; employee.MarriageId = (Guid)row["MarriageId"]; employee.Name = (string)row["Name"]; employee.Nationality = (string)row["Nationality"]; employee.NativeAddr = (string)row["NativeAddr"]; employee.Number = (string)row["Number"]; employee.PartyStatusId = (Guid)row["PartyStatusId"]; employee.Position = (string)row["Position"]; employee.Remarks = (string)SqlHelper.FromDbValue(row["Remarks"]); employee.Resume = (string)SqlHelper.FromDbValue(row["Resume"]); employee.School = (string)SqlHelper.FromDbValue(row["School"]); employee.TelNum = (string)row["TelNum"]; //todo:如果员工非常多，那么Photo会增加内存占用 employee.Photo = (byte[])SqlHelper.FromDbValue(row["Photo"]); return employee; } public Employee[] ListAll() { DataTable dt = SqlHelper.ExecuteDataTable("SELECT * FROM T_Employee where IsStopped = 0"); Employee[] empl = new Employee[dt.Rows.Count]; for (int i = 0; i < dt.Rows.Count; i++) { empl[i] = ToEmployee(dt.Rows[i]); //DataRow row = dt.Rows[i]; //Employee emp = new Employee(); //emp.Id =(Guid) row["Id"]; //empl[i] = emp; } return empl; } public void Insert(Employee employee) { SqlHelper.ExecuteNonQuery(@"INSERT INTO [T_Employee] ([Id],[Number],[Name],[BirthDay],[InDate],[MarriageId],[PartyStatusId],[Nationality] ,[NativeAddr],[EducationId],[Major],[School],[Address],[BaseSalary],[Email] ,[IdNum],[TelNum],[EmergencyContact],[DepartmentId],[Position],[ContractStartDay] ,[ContractEndDay],[Resume],[Remarks],[IsStopped],[GenderId],[Photo]) VALUES(newid(),@Number,@Name,@BirthDay,@InDate,@MarriageId,@PartyStatusId,@Nationality ,@NativeAddr,@EducationId,@Major,@School,@Address,@BaseSalary,@Email ,@IdNum,@TelNum,@EmergencyContact,@DepartmentId,@Position,@ContractStartDay ,@ContractEndDay,@Resume,@Remarks,0,@GenderId,@Photo)", new SqlParameter("@Number", employee.Number) , new SqlParameter("@Name", employee.Name) , new SqlParameter("@BirthDay", employee.BirthDay) , new SqlParameter("@InDate", employee.InDate) , new SqlParameter("@MarriageId", employee.MarriageId) , new SqlParameter("@PartyStatusId", employee.PartyStatusId) , new SqlParameter("@Nationality", employee.Nationality) , new SqlParameter("@NativeAddr", employee.NativeAddr) , new SqlParameter("@EducationId", employee.EducationId) , new SqlParameter("@Major", SqlHelper.ToDbValue(employee.Major)) , new SqlParameter("@School", SqlHelper.ToDbValue(employee.School)) , new SqlParameter("@Address", employee.Address) , new SqlParameter("@BaseSalary", employee.BaseSalary) , new SqlParameter("@Email", SqlHelper.ToDbValue(employee.Email)) , new SqlParameter("@IdNum", employee.IdNum) , new SqlParameter("@TelNum", employee.TelNum) , new SqlParameter("@EmergencyContact", SqlHelper.ToDbValue(employee.EmergencyContact)) , new SqlParameter("@DepartmentId", employee.DepartmentId) , new SqlParameter("@Position", employee.Position) , new SqlParameter("@ContractStartDay", employee.ContractStartDay) , new SqlParameter("@ContractEndDay", employee.ContractEndDay) , new SqlParameter("@Resume", SqlHelper.ToDbValue(employee.Resume)) , new SqlParameter("@Remarks", SqlHelper.ToDbValue(employee.Remarks)) , new SqlParameter("@GenderId", employee.GenderId) , new SqlParameter("@Photo",SqlHelper.ToDbValue(employee.Photo)));

for (int i = 0; i < table.Rows.Count; i++) { items[i] = ToEmployee(table.Rows[i]); } return items; } } }
4、EmployeeListUI界面与交换
