C# 在 64 位计算机上 buildint 后出现“'System.BadImageFormatException' 类型的第一次机会异常”

"A first chance exception of type 'System.BadImageFormatException' " after buildint on a 64-bit computer

提问by Doug Null

My Visual Studio 2010 solution has C DLL and C# project, which calls C DLL. Solution works ok when built on 32-bit Windows-7 Pro computer. On 64-bit Windows-7 Pro, builds okay, but when ran, C# calls function in the DLL and gets error:

我的 Visual Studio 2010 解决方案有 C DLL 和 C# 项目，它们调用 C DLL。解决方案在 32 位 Windows-7 Pro 计算机上构建时运行正常。在 64 位 Windows-7 Pro 上，构建没问题，但是当运行时，C# 调用 DLL 中的函数并得到错误：

A first chance exception of type 'System.BadImageFormatException'

Solution Configuration Manager settings are:

解决方案配置管理器设置为：

<DLL project>   Platform = Win32       (<<< no option to change to "Any CPU")
<C# project>    Platform = "Any CPU"

The output below is:

加载 'C:\Windows\Microsoft.Net\assembly\GAC_64\mscorlib...

Your program is running as a 64-bit process. Your DLL contains 32-bit unmanaged code. Kaboom.

您的程序作为 64 位进程运行。您的 DLL 包含 32 位非托管代码。卡布姆。

You'll need to force your EXE to run as a 32-bit process so that DLL can be loaded. Right-click your EXE project in the Solution Explorer window. Properties, Build tab, change the Platform target setting from AnyCPU to x86. On VS2012 and up tick the "Prefer 32-bit" option. Repeat for the Release configuration.

您需要强制您的 EXE 作为 32 位进程运行，以便可以加载 DLL。在解决方案资源管理器窗口中右键单击您的 EXE 项目。属性，构建选项卡，将平台目标设置从 AnyCPU 更改为 x86。在 VS2012 及更高版本上，勾选“首选 32 位”选项。对发布配置重复此操作。
