我有一个dll。 该 dll 上传到服务器上。 我希望每次应用程序开始从服务器获取“最新”dll，因此我在 app.config 中使用了以下代码。 为什么它不起作用？
这是 app.config 文件：
<configuration>
<runtime>
<assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
<dependentAssembly>
<assemblyIdentity name="ReflectionTest"
publicKeyToken="f94c9b9f0707ee96"
culture="neutral" />
<codeBase version="1.0.0.0"
href="http://127.0.0.1/ReflectionTest.dll"/>
</dependentAssembly>
</assemblyBinding>
</runtime>
</configuration>
I have a dll. That dll is uploaded on a server. I want that each time the application starts to get the "latest" dll from the server, so I've used the following code in my app.config. Why isn't it working?
here is the app.config file:
<configuration>
<runtime>
<assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
<dependentAssembly>
<assemblyIdentity name="ReflectionTest"
publicKeyToken="f94c9b9f0707ee96"
culture="neutral" />
<codeBase version="1.0.0.0"
href="http://127.0.0.1/ReflectionTest.dll"/>
</dependentAssembly>
</assemblyBinding>
</runtime>
</configuration>

首先，你可能走错了路。 即使您没有更改版本，您的应用程序最终也可能会使用程序集的旧副本。
假设
考虑使用反射，而不是使用()。
Assembly.LoadFrom(assembleUri)，从应用程序设置中获取 URI。 从那里，您可以使用 Reflection API 创建对象，特别是使用 Activator.CreateInstance至于从服务器获取该程序集，请确保 DLL 位于正确的位置，并且 Web 服务器正在运行且配置正确。
First, you may be on the wrong track. Even if you didn't change the version, your application may end up using an older copy of the assembly.
Assuming a valid URI in your
<codebase>element, when your application runs for the first time, the runtime will not find the assembly in until it probes your codebase. Then, it will download the assembly to the GAC. When your application runs again, the runtime will find that assembly in the GAC, so it will not need to probe for it.Instead of using
<codebase>, consider using Reflection. Specifically, you might want to useAssembly.LoadFrom(assemblyUri)in your application, getting the URI from an application setting. From there, you'd create objects using the Reflection API, particularly usingActivator.CreateInstance<T>().As for getting that assembly from your server is concerned, make sure that your DLL is in the right location and that your web server is running and properly configured.
您的 .dll 实际上在该位置可用吗？ 您是否通过某些网络应用程序提供服务？
如果您将该 URL 键入网络浏览器，它是否允许您下载或打开该文件？
Is your .dll actually available at that location? Are you serving it up through some web application?
If you type that URL into a web browser, does it let you download or open that file?
