【问题描述】:
我花了一个小时调试这个,我终于消除了 PEBCAK 问题。
我有一个国际化的应用程序。应用程序的一个关键部分使用反射从配置的源加载类型。所以在配置中,有这样一个入口:
<component type="Application.Component" assembly="Application, Version=2.0.0.0, Culture=neutral, PublicKeyToken=0123456789abcdef"/>
应用程序使用以下代码加载组件:
var assembly = Assembly.Load(assemblyName);
var rawComponent = assembly.CreateInstance(typeName, false, BindingFlags.CreateInstance, null, instanceParams, CultureInfo.CurrentUICulture, null);
当我签署代码时失败了。这是融合日志查看器的输出:
*** Assembly Binder Log Entry (2010-10-21 @ 11:10:52) ***
The operation failed.
Bind result: hr = 0x80070002. The system cannot find the file specified.

PEBCAK 是我花了一个小时试图弄清楚多种文化中的附属程序集是否是问题所在。
不,问题是,如果您指定 2.0.0.0 作为版本(请参阅上面的配置 sn-p),并且您的程序集获得了 2.0.3946.17829 的调试版本,那么它是一个不同的版本号。解决方案是将配置更改为:
<component type="Application.Component" assembly="Application, Version=2.0, Culture=neutral, PublicKeyToken=0123456789abcdef"/>
所以我的问题是:我认为您可以指定要加载的版本,CLR 会加载任何更高版本。为什么不是这样?我错过了什么?

“CLR 会加载任何更高版本” - 为什么?
