如何提供一个备用组件，而不是不能装入一个？ [英] How to provide a fallback assembly instead of the one that can't be loaded?

问题描述

在运行时，如果引用的程序集加载失败与如强名称验证失败（因为它的测试签名），有没有办法从另一个路径提供了一个替代组件，它是真正的签名？

At runtime, if a referenced assembly fails to load with e.g. "Strong name validation failed" (because it's test-signed), is there a way to provide a substitution assembly from another path that is real-signed?

我想订阅AppDomain.CurrentDomain.AssemblyResolve，但它并没有被解雇，因为坏组装技术上存在，它只是不能被加载。

I tried subscribing to AppDomain.CurrentDomain.AssemblyResolve, but it doesn't get fired, because the "bad" assembly technically exists, it just can't be loaded.

有没有一种通用的方法来提供一个备用组件当一个组件无法加载？

Is there a generic way to provide a fallback assembly when an assembly can't be loaded?

推荐答案

我觉得你可以叫assembly.LoadFrom加载您所选择的组件，几乎无任何安全检查。摆在我们这个有很多在我们的应用程序，以便我们能够更好地处理与其他组件的版本变化的开始。

I think you can just call assembly.LoadFrom to load the assembly of your choice with practically no security checks. We us this a lot at the start of our app so we can better deal with other assemblies version change.

另外，也要看看 Assembly.LoadFrom方法（字符串，证据，字节[]， AssemblyHashAlgorithm） 貌似可以控制传入散列以及散列算法。

Also look at Assembly.LoadFrom Method (String, Evidence, Byte[], AssemblyHashAlgorithm) looks like you can control passing in the hash as well as the hash algorithm.
