Question

我正在开发一个项目，它使用naudio和naudio.lame捕获扬声器音频并将其写入MP3文件。我从nugget enter link description here向我的项目添加了两个DLL并且它工作正常，但问题是当我转到bin＆gt;发布或调试文件夹然后单击exe然后它显示错误。我将所有DLL复制到该文件夹，并尝试创建新项目，然后添加引用，但没有任何工作仍然显示单击exe时相同的错误。任何帮助感谢

这是错误信息： -

To enable assembly bind failure logging, set the registry value [HKLM\Software\Microsoft\Fusion!EnableLog] (DWORD) to 1.
Note: There is some performance penalty associated with assembly bind failure logging.
To turn this feature off, remove the registry value [HKLM\Software\Microsoft\Fusion!EnableLog].

Answer 1

LameDLLWrap是作为naudio.lame.dll程序集中的资源存储的内部程序集对。根据您运行的位深度，将解压缩并加载32位或64位版本，然后加载相应的libmp3lame dll。因此，必须同时将libmp3lame.32.dll和libmp3lame.64.dll文件与naudio.lame.dll程序集一起部署在您的应用程序中，否则将失败

NuGet包应该将项目配置为包含两个文件，并应设置文件的属性以确保它们被复制到输出。

在项目资源管理器中，确保包含两个本机DLL libmp3lame.32.dll和libmp3lame.64.dll。单击每个属性并检查属性以确保这两个文件的Copy To Output Directory属性都设置为Copy always。

如果没有，请自行设置或使用NuGet删除并重新添加NAudio.Lame包。

如果这不能解决问题，请告诉我，我会看看能否找出问题所在。

我使用Visual Studio 2012和2013测试了NuGet包，最新的NuGet包管理器（v2.7.41101.371）以及所有三个编译目标（x86，x64和{{1 }}）。在所有组合中，它按预期运行。如果您使用的是其他配置，请告知我们您的回复。

** 更新

经过一些游戏后，似乎在IDE外部运行时，某些配置中的Loader未正确初始化存在问题。这是因为没有调用其中一个静态初始化器。

问题已修复，现在NuGet上的v1.0.2正在运行。请更新软件包，然后重试。

Answer 2

确保将所有 dll从库复制到输出文件夹，而不仅仅是您要引用的文件夹。这些只是托管的包装库，需要它们的本地对应物才能工作。与直觉相反，如果找不到依赖库（或者，使用不同的单词，指示的dll不一定是缺少的那个），也会发生此错误。
