我应该如何将WPF MVVM应用于大规模应用程序 [英] How should I approach on applying WPF MVVM to a large scale application

问题描述

我们有一个包含100多个客户的大型winform应用程序。现在我们决定继续推进并使用WPF重新设计应用程序。我已经看了一些关于MVVM模式的例子和以下结构的想法：



服务器端：数据库 - > WCF服务

客户端：DataSource dll（纯数据类）

DataAccess dll（将引用数据源dll并执行数据库相关操作）

BusinessLogic DLL（将引用DataSource和DataAccess dll）

UI_Model dll（将引用DataSource dll和BusinessLogic dll）

UI（将引用UI_Model dll）



请注意我通过为viewModel创建一个单独的dll，从viewmoded（UI_Model）中分离了视图（UI），这是一种正确的方法吗？或者我的视图和viewModel都应该保留在一个项目中？如果有人能告诉我我是在正确的轨道上还是需要改变结构，我将不胜感激。



谢谢

Hi,
We have a large scale winform application with more than 100 clients. Now we have decided to move forward & redesign the app with WPF. I have looked at some examples on MVVM Pattern & thought of below structure:

Server Side: Database -> WCF Service
Client Side: DataSource dll (plain data classes)
DataAccess dll (will refer to data source dll & perform database related operations)
BusinessLogic dll(will refer to DataSource & DataAccess dll)
UI_Model dll (will refer to DataSource dll & BusinessLogic dll)
UI (will refer to UI_Model dll)

Please note I have separated view(UI) from viewmoded (UI_Model) by creating a separate dll for viewModel, is it a correct approach? Or my view & viewModel should both remain in one project? I would appreciate if anyone can suggest me whether I am on a right track or required to change the structure.

Thanks

推荐答案

我不确定你为什么在这里使用UI_Model？会有什么？



我通常在视图模型中使用POCO数据类 - 并将它们包装起来或以其他方式将信息呈现给视图



我还将View和ViewModel分离到解决方案中的不同项目中，View项目引用了ViewModel项目 - 这样我就可以避免意外地从ViewModel引用一些View信息。



所以我通常最终得到：



VIEW绑定到VIEWMODEL，它使用BUSINESSLOGIC提供的DATAOBJECTS通过来自SOMEDATASOURCES的数据库

I'm not sure why you are using a UI_Model here? What would be there?

I normally consume POCO data classes in my view model - and either wrap them or otherwise present the information to the Views

I also separate my View and ViewModel into different projects in the solution, with the View project having a reference to the ViewModel project - that way I avoid accidentally referring to some View information from my ViewModel.

So I normally end up with:

VIEW binds to VIEWMODEL which uses DATAOBJECTS provided by BUSINESSLOGIC via DATASERVICES from SOMEDATASOURCES
