在C#类库中使用MATLAB MWArray.dll

导读：我正在尝试在C#类库中使用带有Matlab .net Complier的MATLAB构建的.dll,但是每次初始化MWArray.dll的对象时程序都会抛出异常,例如： MWNumericArray m = new MWNumericArra(10,10); 例外： System.TypeInitializationException was caught HResult=-21462330

我正在尝试在C#类库中使用带有Matlab .net Complier的MATLAB构建的.dll,但是每次初始化MWArray.dll的对象时程序都会抛出异常,例如：

MWNumericArray m = new MWNumericArra(10,10);

例外：

我尝试在Console App中执行此操作,并且工作正常,但我需要.dll使用matlab内置的.dll.

有任何想法吗？

解决方法

帮助我的是确保C#应用程序和matlab模块在相同的架构下 – 意思是32位或64位.

如果您的Matlab是64位 – 尝试将C#项目更改为64位
