如何允许两个具有相同namespace.class的DLL存在于同一个应用程序中？ [英] How do you allow two DLL's with same namespace.class to exist in the same application?

问题描述

具体来说，我们试图将我们的telerik控件升级到最新版本。不幸的是，旧的DLL是如此老，许多控制属性已经发生了巨大的变化，所以我们决定只升级给我们的问题（RadEditor控件）的telerik控件。

Specifically, we are trying to upgrade our telerik controls to the latest version. Unfortunately, the old DLL's are so old that many of the control properties have changed vastly so we've decided to upgrade only the telerik control that is giving us problems (the RadEditor control).

所以bin看起来像这样：

So the bin looks something like this:

RadChart.Net2.dll
RadEditor.Net2.dll (we want to get rid on only this one)
RadGrid.Net2.dll
RadInput.Net2.dll
RadPanelbar.Net2.d
RadSpell.NET2.dll
RadTabStrip.Net2.d
RadToolbar.Net2.dl
RadTreeView.Net2.d
RadUpload.Net2.dll
RadWindow.Net2.dll
Telerik.Web.UI.dll (this is the new DLL)

问题是所有的命名空间和类都是

The problem is that all the namespaces and classes are the same from the old DLLs to the new one (Telerik.Web.UI).

这是我遇到的具体错误：

Here is the specific error I am getting:

Compilation Error

Description: An error occurred during the compilation of a resource required to service this request. Please review the following specific error details and modify your source code appropriately. 

Compiler Error Message: CS0433: The type 'Telerik.Charting.ChartSeries' exists in both 'c:\Windows\Microsoft.NET\Framework64\v2.0.50727\Temporary ASP.NET Files\root\c6516654\63e1c826\assembly\dl3\9aa96a66\00ba04b3_fd85c701\RadChart.Net2.DLL' and 'c:\Windows\Microsoft.NET\Framework64\v2.0.50727\Temporary ASP.NET Files\root\c6516654\63e1c826\assembly\dl3\8fdb0e6c\001aa55c_c4f9c901\Telerik.Web.UI.DLL'

我考虑过GAC的新DLL，但我不确定这将有助于这种情况。

I've considered GAC-ing the new DLL but I am uncertain that this will help the situation. Any help would be greatly appreciated.

推荐答案

您可以使用extern别名（教程和参考），以区分它们。这是很讨厌的，必须，不可否认，显然避免在哪里，但至少C＃提供了一种方式：）

You can use extern aliases (tutorial and reference) to differentiate between them. It's pretty annoying to have to, admittedly - obviously avoid where you can, but at least C# provides a way round it :)
