.NET - 具有相同命名空间的多个库 - 引用 [英] .NET - Multiple libraries with the same namespace - referencing

问题描述

今天我面临着一个奇怪的挑战......

这个挑战涉及我需要从我的应用程序中引用的两个 .NET 库.两者我都无法控制，并且在它们中具有相同的命名空间.

所以...

我的 foo.dll 包含一个 Widget 类，该类位于 Blue.Red.Orange 命名空间中.

我的 bar.dll 还包含一个 Widget 类，该类也位于 Blue.Red.Orange 命名空间中.p>

最后，我的应用程序需要同时引用 foo.dll 和 bar.dll.这是需要的，因为在我的应用程序中，我需要使用 foo 中的 Widget 类以及 bar 中的 Widget 类>

那么，问题是如何管理这些引用，以便确定我使用的是正确的 Widget 类?

如前所述，我无法控制 foo 或 bar 库，它们就是它们的本来面目，无法更改.但是，我可以完全控制我的应用程序.

解决方案

您需要使用 extern alias - 在 C# 2 中引入.

Anson Horton 在他的博客上有一个演练，您可以觉得有用.

Today I am faced with a curious challenge...

This challenge involves two .NET libraries that I need to reference from my application. Both of which I have no control over and have the same namespace within them.

So...

I have foo.dll that contains a Widget class that is located on the Blue.Red.Orange namespace.

I have bar.dll that also contains a Widget class that is also located on the Blue.Red.Orange namespace.

Finally I have my application that needs to reference both foo.dll and bar.dll. This is needed as within my application I need to use the Widget class from foo and also the Widget class from bar

So, the question is how can I manage these references so that I can be certain I am using the correct Widget class?

As mentioned, I have no control over the foo or bar libraries, they are what they are and cannot be changed. I do however have full control over my application.

解决方案

You need to use an extern alias - introduced in C# 2.
