dll Matlab实例在c#中运行release时抛出异常

Question

我的 c# 程序使用 Matlab dll，只要我在调试模式下运行它就可以找到它。 但是当我尝试在发布模式下运行它时，它会在创建实例时立即崩溃。

它引发 TypeInitializationException。

感谢您的帮助

它说：

The type initializer for 'MatlabANNComp.MatlabANN' threw an exception.

异常消息：

Exception.Message = 
"The type initializer for 'MatlabANNComp.MatlabANN' threw an exception."

InnerException.Message =
{"Could not load file or assembly 'MWArray, Version=2.10.1.0, 
Culture=neutral, PublicKeyToken=e1d84a0da19db86f' 
or one of its dependencies. An attempt was made

InnerException.InnerException = null

Answer 1

An attempt was made to load a program with an incorrect format

这是关键，这意味着您正在混合平台。 32 位进程无法加载 64 位 dll，反之亦然。如果一个进程无论如何都试图这样做，它会抛出上述异常。 你说你只是从 Debug->Release 改变的，所以它很可能与平台改变有关。比较配置管理器中所有项目的设置。它们都应该是 x86 或 x64（不是 AnyCPU）。哪一个取决于您的 matlab dll 的平台（在构建时设置）。
