deepload的递归指的是什么, 何时用deepload的递归?
让我举个例子来说明这些问题吧
以下我们以node来举例
数据结构
id是主键, pid是外键
生成后并使用deepload, deepload的参数说明可以看第一篇文章
Node node = DeepLoadById(1, false, DeepLoadType.IncludeChildren, typeof(Node), typeof(TList<Node>));
此时我们可以使用
node.PidSource 类型为Node
node.NodeCollection 类型为TList<Node>
node.NodeCollection[0] 类型为Node
分别表示父节点,和子节点集合
那么我们要取父节点的父节点该如何取呢?
聪明的宁一定想到了 node.PidSource.PidSource
可为什么取出来是null呢?
因为我们没有使用递归
我们将代码改为
Node node = DeepLoadById(1, true, DeepLoadType.IncludeChildren, typeof(Node), typeof(TList<Node>));
好了, 这样便完成了 对id==1 的node 的读取, 并且读取出所有的父节点(递归)及子节点(递归)
关于日志:
nettiers使用了 Microsoft.Practices.EnterpriseLibrary.Logging
使用起来很方便
Logger.Write(obj);
就可以写入日志了, 关于Logging Application Block 的配置, 大家可以搜一下cnblogs以前的文章, 有很多介绍
关于异常:
nettiers使用了Microsoft.Practices.EnterpriseLibrary.ExceptionHandling
使用起来同样很方便...
ExceptionPolicy.HandleException(exceptionToHandle, policyName)
配置都在entlib.config中
发一个entlib.config
Code

摘要: NetTiers 生成完毕后,默认会在Service层使用logging
但是在默认情况下,被捕获的异常没有被抛出,

摘要: 扩展1个属性 ContractPersonName , 这个属性需要Deepload Users表 才能得到
所以加了判断,如果没有DeepLoad则会抛出异常
建一个实体数据源和一个GridView,允许DeepLoad但不允许递归,不允许事务,允许分页和排序,使用GetPaged方法进行查询
DeepLoad Users对象,再添加5个参数,4个输入,1个输出,PageIndex,OrderBy和PageSize都取GridView的属性
最后再添加一个过滤的参数...
到底是网页绑定好还是后台绑定好,也要看具体的情况而定~
如果太复杂...还是后台吧...

摘要: 1. 设置自定义存储过程的前缀 {0}==表名, {1}==存储过程前缀(可有可无),
我这里是ups_{0}_ == usp_表名_方法名
2.建立存储过程,名称为usp_tblUsers_GetByUserName
3.GetByUserName方法将出现在UsersProvider下
到这一步就完成了,值得注意的是,存储过程的写法有一定讲究
关键是那个as, 一定要顶格...前面不能有东西...为了这个...我白白浪费了1个小时....
btw, 如果存储过程的返回类型,不是预期的类型(如:表,int等),则返回模板中选择的类型 DataSet 或iDataReader
也可以通过以下方法访问
DataRepository.Provider.ExecuteDataSet();
DataRepository.Provider.ExecuteNonQuery();
DataRepository.Provider.ExecuteReader();
