设计数据库表T_OperationLog。如下：

在MOdel中建一个T_OperationLog类，代码如下;

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace HRMSys.Model
{
    public class T_OperationLog
    {
        public System.Guid Id { get; set; }
        public System.Guid OperatorId { get; set; }
        public System.DateTime MakeDate { get; set; }
        public System.String ActionDesc { get; set; }
    }

}

 第二步：在DAL中新建一个T_OperationLogDAL类，代码如下：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using HRMSys.Model;
using System.Data.SqlClient;
using System.Data;

namespace HRMSys.DAL
{
    public class T_OperationLogDAL
    {
        private T_OperationLog ToModel(DataRow row)
        {
            T_OperationLog model = new T_OperationLog();
            model.Id = (System.Guid)SqlHelper.FromDbValue(row["Id"]);
            model.OperatorId = (System.Guid)SqlHelper.FromDbValue(row["OperatorId"]);
            model.MakeDate = (System.DateTime)SqlHelper.FromDbValue(row["MakeDate"]);
            model.ActionDesc = (string)SqlHelper.FromDbValue(row["ActionDesc"]);
            return model;
        }

        public void Insert(Guid operatorId, string actionDesc)
        {
            SqlHelper.ExecuteNonQuery(@"insert into T_OperationLog(
            Id,OperatorId,MakeDate,ActionDesc)
            values(newid(),@OperatorId,getdate(),@ActionDesc)", new SqlParameter("@OperatorId", operatorId)
                 , new SqlParameter("@ActionDesc", actionDesc));
        }

        public T_OperationLog[] Search(string sql, SqlParameter[] parameters)
        {
            DataTable table = SqlHelper.ExecuteDataTable(sql, parameters);
            T_OperationLog[] logs = new T_OperationLog[table.Rows.Count];
            for (int i = 0; i < table.Rows.Count; i++)
            {
                logs[i] = ToModel(table.Rows[i]);
            }
            return logs;
        }
    }
}

第三步：因为在登录时候要记录登陆的相关信息，所以在LoginWindown的login_Click事件中if语句和else中添加代码

new T_OperationLogDAL().Insert(op.Id,"登陆成功！");

new T_OperationLogDAL().Insert(op.Id,"登陆不成功！");

在管理者的UI页面即OperatorListUI.cs中删除操作代码内添加代码

 new T_OperationLogDAL().Insert(*****, "删除管理员"+op.UserName);//****是记录的是操作者的ID

因为要记录是谁进行删除的删除操作，使用亦需要在登陆界面中的LoginWindown的login_Click事件中添加代码如下：

    //把登录操作者的Id保存到全局的“Session”
    //存到Application.Current.Properties里面的在程序其他地方也可以取
     Application.Current.Properties["OperatorId"] = op.Id;

在在管理者的UI页面即OperatorListUI.cs中删除操作代码内添加代码如下：取得操作者的ID

   //因为每次都在进行操作时候这样写比较麻烦。所以封装成方法，存在commonHelper.cs中
               // Guid operatorId = (Guid)Application.Current.Properties["OperatorId"];
                Guid operatorId = CommonHelper.GetOperatorId();
                new T_OperationLogDAL().Insert(operatorId, "删除管理员成功"+op.UserName);

在CommonHelper.cs中添加代码如下：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Windows;

namespace HRMSys.UI
{
    public class CommonHelper
    {
        
        /// <summary>
        /// 获得登录用户的Id
        /// </summary>
        /// <returns></returns>
        public static Guid GetOperatorId()
        {
            Guid operatorId = (Guid)Application.Current.Properties["OperatorId"];
            return operatorId;
        }
    }
}

在EmployeeEditWindow新增员工界面页添加如下代码：

 Guid operatorId = CommonHelper.GetOperatorId();
                    new T_OperationLogDAL().Insert(operatorId, "新增职员" + employee.Name);

修改员工时候：

Guid operatorId = CommonHelper.GetOperatorId();
                new T_OperationLogDAL().Insert(operatorId, "修改职员" + employee.Name);
           

在操作员管理界面即OperatorEditorWindow中添加，删除，修改操作员中添加代码如下：

Guid operatorId = CommonHelper.GetOperatorId();
                new T_OperationLogDAL().Insert(operatorId, "新增操作员" + txtUserName.Text);

 Guid operatorId = CommonHelper.GetOperatorId();
                new T_OperationLogDAL().Insert(operatorId, "修改操作员" + txtUserName.Text);
