c# - 错误 'Emgu.CV.CvInvoke' 的类型初始值设定项引发了 C#、Opencv 和 EmguCv 的异常

Question

我已经使用 EmguCV 在 C# 中编写了一个简单的程序来面对检测到的 VS 2010，但我收到以下异常:

The type initializer for 'Emgu.CV.CvInvoke' threw an exception.

我正在尝试修复此链接:http://www.emgu.com/wiki/index.php/Download_And_Installation#The_type_initializer_for_.27Emgu.CV.CvInvoke.27_threw_an_exception

我复制了所有的dll，但仍然出错。

我使用 window 7 pro x86、VS 2010、EmguCV2.4.2 并遵循本教程:http://www.youtube.com/watch?v=vdjoutNR2DQ

帮帮我!

@Marc Gravell:这是我的问题

just-in-time (JIT) debugging instead of this dialog box.

************** JIT Debugging **************
To enable just-in-time (JIT) debugging, the .config file for this
application or computer (machine.config) must have the
jitDebugging value set in the system.windows.forms section.
The application must also be compiled with debugging
enabled.

For example:

    <configuration>
    <system.windows.forms jitDebugging="true" />
    </configuration>

    When JIT debugging is enabled, any unhandled exception
    will be sent to the JIT debugger registered on the computer
    rather than be handled by this dialog box.
