的MissingMethodException抛出GetExportedTypes [英] MissingMethodException thrown by GetExportedTypes

问题描述

我收到抛出的MissingMethodException当我打电话GetExportedTypes，在code：

I'm getting a MissingMethodException thrown when I call GetExportedTypes, the code:

Assembly.LoadFrom(assemblyPath).GetExportedTypes();

例外（名称混淆）：

The exception (names obfuscated):

System.MissingMethodException was unhandled
  Message="Method not found: 'Void Namespace.IMyMethod.MyMethod(UInt32, Namespace.IMyOtherMethod ByRef, UInt32 ByRef)'."
  Source="mscorlib"
  StackTrace:

       at System.Threading.ThreadHelper.ThreadStart()
  InnerException:

的异常没有内部异常或其它细节值得一提。

The exception has no inner exception or other details worth mentioning.

是什么原因造成的？我该如何解决这个问题？

What causes this? How can I fix it?

反射器没有问题，加载这个组件：

Reflector has no problems loading this assembly:

• 这是注册在GAC
• 只引用mscorlib中。
• 在我没有建立组装 - 只有1我的机器上版本的程序集

更新：

在问题的组件，似乎是一个组件内置使用的 Tlbexp.exe - 这很可能是这个正在某种差异

The assembly in question appears to be an assembly built using Tlbexp.exe - it seems likely that this is making some sort of difference.

推荐答案

据我可以看到它只是预计某些组件抛出此异常 - 的 GetTypes 方法抛出了类似的例外 - ReflectionTypeLoadException ，但此异常也有一个<一个href="http://msdn.microsoft.com/en-us/library/system.reflection.reflectiontypeloadexception.types.aspx"相对=nofollow>类型中这似乎是被成功加载类型的列表属性。

As far as I can see it is simply expected that certain assemblies throw this exception - the GetTypes method throws a similar exception - ReflectionTypeLoadException, however this exception also has a Types property which appears to be the list of types that were successfully loaded.

现在我已经适应我的code，使其调用此方法，而不是和捕捉由此导致的异常：

For now I have adapted my code so that it calls this method instead and catches the resulting exception:

try
(
    return assembly.GetTypes();
)
catch (ReflectionTypeLoadException ex)
{
    return ex.Types;
}

它不是pretty的，但它似乎工作。

Its not pretty, however it does appear to work.
