是否有可能在不同的组件再present同一类两个部分类？ [英] Is it possible to have two partial classes in different assemblies represent the same class?

问题描述

我有一个名为在一个名为MyProject.Data项目第级，它充当我的Web应用程序的数据层。

I have a class called 'Article' in a project called 'MyProject.Data', which acts as the data layer for my web application.

我有一个单独的项目叫做MyProject.Admin'，这是用于查看/编辑数据的基于Web的管理系统，并使用ASP.NET动态数据被构建。

I have a separate project called 'MyProject.Admin', which is a web-based admin system for viewing/editing the data, and was build using ASP.NET Dynamic Data.

基本上我要扩展Article类，使用部分类，这样我就可以增强其与UIHint扩展，这将让我有一个FCKEDIT控制取代普通的多行文本框的属性之一。

Basically I want to extend the Article class, using a partial class, so that I can augment one of its properties with a "UIHint" extender, which will allow me to replace the normal multi-line textbox with an FCKEdit control.

我的部分类和扩展是这样的：

My partial class and extender would look like this:

[MetadataType(typeof(ProjectMetaData))]
public partial class Project
{
}

public class ProjectMetaData
{
    [UIHint("FCKeditor")]
    public object ItemDetails { get; set; }
}

现在如果局部类是在同一个项目的原始部分类所有这一切工作正常 - 即MyProject.Data项目

Now this all works fine if the partial class is in the same project as the original partial class - i.e. the MyProject.Data project.

不过，UI的行为不应该坐在数据层，而是在管理层。所以我想这个类移动到MyProject.Admin。

But UI behavior shouldn't sit in the Data layer, but rather, in the Admin layer. So I want to move this class to MyProject.Admin.

但是，如果我这样做，功能丧失。

However, if I do that, the functionality is lost.

我的基本问题是：我可以在不同的项目2个部分类，但都指的是同一类

My fundamental question is: can I have 2 partial classes in separate projects, but both referring to the same "class"?

如果没有，有没有办法来完成我想要做的，没有数据层逻辑与UI逻辑混？

If not, is there a way to accomplish what I'm trying to do, without mixing data-layer logic with UI logic?

推荐答案

没有，你不能指的是同一类两种不同的组件（项目）两个部分类。一旦该程序集编译，元数据出炉，而且可以使用类不再分。部分类可以让你在同一类的定义分为两个文件。

No, you cannot have two partial classes referring to the same class in two different assemblies (projects). Once the assembly is compiled, the meta-data is baked in, and your classes are no longer partial. Partial classes allows you to split the definition of the same class into two files.
