在C＃单元测试中使用64位本机.DLL

Question

我有一个由CMake自动生成的vcxproj文件构建的64位本机库。部分CMake构建脚本自动生成csharp中的Swig文件。我使用下面标记为.csproj的.csproj生成.cs文件，该文件标记为Articaft 1。然后，我有一个C＃单元测试项目神器2低于它引用从Articaft 1产生的.dll文件。 Articafct 2也复制由64位原生库生成的dll。

如果我编译为32位库一切工作正常，但如果我去使用64位本机库中的C＃单元测试项目，测试失败，本机库：

C:\Users\mehoggan\Devel\QuadKeys\UnitTestCSharp\TestBingSystem.cs:line 13 
Result Message: 
Test method QuadKeyTests.TestBingSystem.TestCtor threw exception: 
System.TypeInitializationException: The type initializer for 'QuadKeyNS.SwigQuadKeyPINVOKE' threw an exception. ---> System.TypeInitializationException: The type initializer for 'SWIGExceptionHelper' threw an exception. ---> System.BadImageFormatException: An attempt was made to load a program with an incorrect format. (Exception from HRESULT: 0x8007000B) 

如何如何让我的C＃单元测试使用库的64位版本？

Answer 1

您正在运行VSTest作为32位进程。在Visual Studio的测试菜单中，您会发现一个设置，告诉VSTest以32位或64位进程运行。只需将其更改为64位，并将您的单元测试程序集作为AnyCPU。

Answer 2

你公顷已经指定C＃项目应该只能作为64位程序运行。将“AnyCPU”目标更改为“x64”（我想;我要离开内存）。这将告诉托管编译器生成64位代码而不是32位。
