先来了解下各项的引用关系

FytCms.DALMSSQL=》Domain.Entity、EntityFramework

BusinessLogic.Server=》FytCms.DALMSSQL

FytCms.Web=》FytCms.Helper、Domain.Entity，BusinessLogic.Server，FytCms.Common

ok 简单吧，哇咔咔

 

1、在Core.Repository文件夹下，建FytCms.DALMSSQL类库

这个类库主要的意思就是操作sql server的，当然你可以建FytCms.DALMySql类库，在类库增加方法

主要使用EF操作数据

/// <summary>/// 实现接口基类/// <remarks>创建：2015.05.04 FUYU/// </remarks>/// </summary>/// <typeparam name="T">类型</typeparam>public class BaseRepository<T> where T : class ,new(){/// <summary>/// 获得数据上下文/// </summary>protected FytSysDbContext FytContext = new FytSysDbContext();#region 1、添加/// <summary>/// 添加/// </summary>/// <param name="entity">数据实体</param>/// <param name="isSave">是否保存</param>/// <returns>添加后的数据实体</returns>public T Add(T entity, bool isSave = true){FytContext.Set<T>().Add(entity);if (isSave) FytContext.SaveChanges();return entity;}/// <summary>/// 同时增加多条数据到一张表（事务处理）/// </summary>/// <param name="entitys"></param>/// <returns></returns>public bool AddEntity(List<T> entitys){foreach (var entity in entitys){FytContext.Entry<T>(entity).State = System.Data.Entity.EntityState.Added;}return FytContext.SaveChanges() > 0;}#endregion#region 2、修改/// <summary>/// 更新/// </summary>/// <param name="entity">数据实体</param>/// <param name="isSave">是否保存</param>/// <returns>是否成功</returns>public bool Update(T entity, bool isSave = true){FytContext.Set<T>().Attach(entity);FytContext.Entry<T>(entity).State = System.Data.Entity.EntityState.Modified;return !isSave || FytContext.SaveChanges() > 0;}/// <summary>/// 同时更新多条数据（事务处理）/// </summary>/// <param name="entitys">数据实体</param>/// <returns>是否成功</returns>public bool Update(List<T> entitys){entitys.ForEach(entity =>{FytContext.Set<T>().Attach(entity);FytContext.Entry<T>(entity).State = System.Data.Entity.EntityState.Modified;//将所有属性标记为修改状态

数据操作做好，下一步就是业务调用数据操作，

 

2、建立业务类

在BusinessLogic.Server文件夹下增加BusinessLogic.Server类库，

在该类库引用FytMsys.DALMSSQL

新建类BaseServer   具体代码如下

/// <summary>/// BLL层抽象类/// <remarks>创建：2015.05.04 FUYU/// </remarks>/// </summary>/// <typeparam name="T">类型</typeparam>public class BaseServer<T> where T : class,new(){/// <summary>/// 实例化数据层方法/// </summary>protected BaseRepository<T> Repository=new BaseRepository<T>();#region 1、添加/// <summary>/// 添加/// </summary>/// <param name="entity">数据实体</param>/// <param name="isSave">是否保存</param>/// <returns>添加后的数据实体</returns>public T Add(T entity, bool isSave = true){return Repository.Add(entity,isSave);}/// <summary>/// 同时增加多条数据到一张表（事务处理）/// </summary>/// <param name="entitys"></param>/// <returns></returns>public bool AddEntity(List<T> entitys){return Repository.AddEntity(entitys);}#endregion#region 2、修改/// <summary>/// 更新/// </summary>/// <param name="entity">数据实体</param>/// <param name="isSave">是否保存</param>/// <returns>是否成功</returns>public bool Update(T entity, bool isSave = true){return Repository.Update(entity,isSave);}/// <summary>/// 同时更新多条数据（事务处理）/// </summary>/// <param name="entitys">数据实体</param>/// <returns>是否成功</returns>public bool Update(List<T> entitys){return Repository.Update(entitys);}/// <summary>/// 修改一条数据,会修改指定列的值/// </summary>/// <returns>是否成功</returns>public bool Update(T entity, params string[] proNames){return Repository.Update(entity,proNames);}#endregion#region 3、删除/// <summary>/// 删除/// </summary>/// <param name="entity">数据实体</param>/// <param name="isSave">是否保存</param>/// <returns>是否成功</returns>public bool Delete(T entity, bool isSave = true){return Repository.Delete(entity,isSave);}/// <summary>/// 根据条件删除/// </summary>/// <param name="delWhere">删除表达式</param>/// <param name="isSave">是否保存</param>/// <returns>是否成功</returns>public bool DeleteBy(Expression<Func<T, bool>> delWhere, bool isSave = true){return Repository.DeleteBy(delWhere,isSave);}/// <summary>/// 批量物理删除数据,也可以用作单个物理删除--此方法适用于id为int类型的表--性能会比先查询后删除快/// </summary>/// <param name="ids">ID集合1,2,3</param>/// <returns>是否成功</returns>public bool DeletePhysics(string ids){return Repository.DeletePhysics(ids);}#endregion#region 4、查询/// <summary>/// 是否存在/// </summary>/// <param name="anyLambda">查询表达式</param>/// <returns>布尔值</returns>public bool Exist(Expression<Func<T, bool>> anyLambda){return Repository.Exist(anyLambda);}/// <summary>/// 查询记录数/// </summary>/// <param name="predicate">条件表达式</param>/// <returns>记录数</returns>public int Count(Expression<Func<T, bool>> predicate){return Repository.Count(predicate);}/// <summary>/// 查询数据根据ID主键(优先)/// </summary>/// <param name="id">主键</param>/// <returns>实体</returns>public T GetModel(int id){return Repository.GetModel(id);}/// <summary>/// 查询数据/// </summary>/// <param name="whereLambda">查询表达式</param>/// <returns>实体</returns>public T GetModel(Expression<Func<T, bool>> whereLambda){return Repository.GetModel(whereLambda);}/// <summary>/// 查找数据列表/// </summary>/// <typeparam name="TKey"></typeparam>/// <param name="whereLamdba">查询表达式</param>/// <param name="orderLambda">排序表达式</param>/// <param name="isAsc">是否升序</param>/// <returns></returns>public IQueryable<T> GetList<TKey>(Expression<Func<T, bool>> whereLamdba, Expression<Func<T, TKey>> orderLambda, bool isAsc){return Repository.GetList(whereLamdba,orderLambda,isAsc);}#endregion#region 5、分页/// <summary>/// 查找分页数据列表/// </summary>/// <typeparam name="TKey">排序</typeparam>/// <param name="pageIndex">当前页</param>/// <param name="pageSize">每页记录数</param>/// <param name="rows">总行数</param>/// <param name="totalPage">分页总数</param>/// <param name="whereLambda">查询表达式</param>/// <param name="isAsc">是否升序</param>/// <param name="orderBy">排序表达式</param>/// <returns></returns>public IQueryable<T> GetPageList<TKey>(int pageIndex, int pageSize, out int rows, out int totalPage,Expression<Func<T, bool>> whereLambda, bool isAsc, Expression<Func<T, TKey>> orderBy){return Repository.GetPageList(pageIndex,pageSize,out rows,out totalPage,whereLambda,isAsc,orderBy);}#endregion}

 

可以在次扩展业务方法，也可以新建一个自定义类库引用BusinessLogic.Server  在自定义类库新建自定义类扩展方法

要一步要做的就是WebUi层、
