如何在不使用WCF的情况下将表示层连接到DataEntity层

本文介绍了如何在不使用WCF的情况下将表示层连接到DataEntity层的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

我要按照以下步骤进行操作: msdn.microsoft/en-us/library/bb384570.aspx [ ^ ] 但是客户端告诉我不要在数据实体层和表示层之间使用WCF服务.也不提供Web服务或任何形式的任何服务.所以我改为放入类库. 还是应该在表单上以某种方式直接链接到DataEntityTier的DataGridView放下? 我已经尝试过将一个类库放在一起作为中间对象，并将其用作对象数据源. BindingNavigator可以正常运行，但不会填充gridview. Brian

解决方案

看看如何:将对象绑定到Windows窗体控件 [ ^ ]-无需在两者之间放任何东西.如果您想使用DataSet，DataTable和适配器，我认为最好坚持使用旧的" Fill方式. 另一种方法是使用类似以下内容的方法:数据库助手v 2.0.0 [ ^ ] 最好的问候 Espen Harlinn

在这种情况下， MVP [ ^ ]模式非常好.

I want to follow the procedure at: msdn.microsoft/en-us/library/bb384570.aspx[^] but the client has told me not to use a WCF service in between the Data Entity Layer and the Presentation Tier. Nor a web service or any service of any kind. So I put in a Class Library instead. Or should I plop down a DataGridView on my form that''s linked directly to the DataEntityTier somehow? I''ve already tried putting together a class library to serve as the go-between and using it as an Object Data Source. The BindingNavigator works OK but the gridview won''t populate. Brian

解决方案

Take a look at How to: Bind Objects to Windows Form Controls[^] - no need to put anything between. If you want to use DataSet, DataTable and adapters, I think it''s better to just stick with the "old" Fill way of doing things. An aternative is to use something like:Database Helper v 2.0.0[^] Best regards Espen Harlinn

For such case an MVP[^] pattern is quite good.
