DotNet 控制台应用程序崩溃并显示消息“FileNotFoundException”。虽然 dll 存在并且正在加载

Question

我有一个简单的控制台应用程序，它使用第三方 dll（32 位）（它依赖于另外两个 dll，复制到同一路径）和 dotnet 框架 4.5。此应用程序适用于本地 Windows 7 机器。但是在 windows server 2012 R2 中运行时同样会崩溃并显示以下消息。

System.IO.FileNotFoundException: Could not load file or assembly 'dcasdk.dll' or one of its dependencies. The specified module could not be found.
File name: 'dcasdk.dll'

来自事件查看器：

Faulting application name: ConsoleApplication2.exe, version: 1.0.0.0, time stamp: 0x590c51de
Faulting module name: KERNELBASE.dll, version: 6.3.9600.18340, time stamp: 0x5736541b
Exception code: 0xe0434352
Fault offset: 0x00014878
Faulting process id: 0x9a4
Faulting application start time: 0x01d2c5898c929ee7
Faulting application path: C:\Debug\ConsoleApplication2.exe
Faulting module path: C:\Windows\SYSTEM32\KERNELBASE.dll
Report Id: ca4bbc88-317c-11e7-818e-0ac916d6c5ab
Faulting package full name: 
Faulting package-relative application ID: 

错误消息日志会记录以下消息，尽管所有三个 dll 都在同一个位置。

System.IO.FileNotFoundException: Could not load file or assembly 'dcasdk.dll' or one of its dependencies. The specified module could not be found.
File name: 'dcasdk.dll'

我尝试使用 x86 编译应用程序，这很有帮助。

任何有关如何找到根本原因\是什么导致 dcasdk dll 加载失败的帮助......都会有所帮助。

融合日志

Fusion 日志显示加载成功。尽管应用程序崩溃，但与任何其他 dll 相关的融合日志中没有错误。

Answer 1

安装 MIcrosoft Visual C++ redistributable package(x86) 解决了这个问题。 依赖步行者具有误导性。我能够使用 Process Monitor 工具找到根本原因。

谢谢。

Answer 2

我没有足够的代表来发布 cmets，但这可能与 BadImageFormatException Could not load file or assembly or one of its dependencies. An attempt was made to load a program with an incorrect format 重复

在仅定位x86 之前，您的平台目标是AnyCPU 吗？另外，dcasdk.dll 你确定它也针对AnyCPU 并且不是针对特定平台的吗？
