[英]How to add VB.NET Class to GAC, and use it in Code-Behind
I created a VB.NET Class, and created a strong key, and added it to the GAC using the GacUtil. 我创建了VB.NET类,并创建了一个强键,然后使用GacUtil将其添加到GAC中 。 That part has gone smoothly.
那部分进展顺利。 The Assembly is installed in the GAC and seems to be installed/configured correctly.
程序集已安装在GAC中,并且似乎已正确安装/配置。
FYI, the assembly is a Class called Tester, that exposes one public static method called HelloWorld, which returns a string, "Hello World". 仅供参考,程序集是一个称为Tester的类,它公开一个名为HelloWorld的公共静态方法,该方法返回字符串“ Hello World”。
The next step was to create a test web application (VB.NET and ASP.NET 2.0), using Visual Studio 2005, Windows XP SP3. 下一步是使用Visual Studio 2005,Windows XP SP3创建一个测试Web应用程序(VB.NET和ASP.NET 2.0)。 I created the test web application and added the following to the web.config file's configuration section.
我创建了测试Web应用程序,并将以下内容添加到了web.config文件的配置部分。
<assemblies>
<add assembly="BenGACTest, Version=1.0.0.0, Culture=neutral, PublicKeyToken=3e5b6cecb56999ca" />
</assemblies>
I then added some inline code to my aspx page as follows: 然后,我向aspx页面添加了一些内联代码,如下所示:
<div><%=BenGACTest.Tester.HelloWorld()%></div>
When I run the page in the web browser, indeed everything works as expected. 当我在网络浏览器中运行该页面时,实际上一切正常。 The page outputs "Hello World" and all seems good.
页面输出“ Hello World”,一切似乎都很好。
However, I don't know how to use this code in the code-behind page. 但是,我不知道如何在代码隐藏页面中使用此代码。 I try to import the assembly, just like "imports system" and it doesn't appear in the IntelliSense.
我尝试导入程序集,就像“导入系统”一样,它没有出现在IntelliSense中。
Also, when I try to add the assembly as a reference to the project, the assembly is not found in the list of installed assemblies. 另外,当我尝试将程序集添加为对项目的引用时,在已安装的程序集列表中找不到该程序集。 I believe this is because the list is pulled from the registry, not from a dynamic list of installed assemblies.
我相信这是因为该列表是从注册表中提取的,而不是从已安装程序集的动态列表中提取的。
My goal is to add the assembly via the web.config file, not by adding it as a project reference, and to use the assembly in the code-behind page. 我的目标是通过web.config文件而不是通过将其添加为项目引用来添加程序集,并在代码隐藏页中使用该程序集。
Any ideas? 有任何想法吗?
You can just reference a local version to use the DLL in Visual Studio, .NET will favour the GAC version when running the application. 您可以引用本地版本以在Visual Studio中使用DLL,.NET在运行应用程序时将优先使用GAC版本。 Furthermore, I don't believe you have to ship the DLL when it's available in GAC, yet you have to reference it through menu Project->Add Reference.
此外,我认为当GAC中提供DLL时,您不必交付DLL,而必须通过菜单Project-> Add Reference来引用它。
