下面介绍如何将系统操作日志集成到你的业务系统中

添加操作：

EmployeeBllbll=newEmployeeBll();

EmployeeModelmodel=newEmployeeModel();

/*model实体经过漫长的赋值后…*/

bll.Add(model);//添加实体

//添加系统操作记录

//日志LogManager<EmployeeModel>log=newLogManager<EmployeeModel>();

log.Add(model);

更新操作：

EmployeeBllbll=newEmployeeBll();

EmployeeModelmodel=bll.GetModel(employeeID);

LogManager<EmployeeModel>log=newLogManager<EmployeeModel>();

EmployeeModelmodelOld=log.Clone(model);//克隆EmployeeModel实体对象，这个主要是在系统操作日志记录时使用的

/*model实体又经过漫长的赋值后…*/

bll.Update(model);//更新实体

//将更新的内容写入系统操作日志中

log.Compare(modelOld,model);//原来的实体和赋值后的实体对比，并将更新的内容写入系统操作日志中

删除操作：

在GridView的RowDeleting事件中获取要删除的实体

EmployeeBllbll=newEmployeeBll();

EmployeeModelmodel=bll.GetModel(employeeID);

bll.Delete(employeeID);

LogManager<EmployeeModel>log=newLogManager<EmployeeModel>();
log.Delete(model);//实体的内容记录到日志中
