BadImageFormatException 故障排除 [英] Troubleshooting BadImageFormatException

问题描述

我有一个使用 Visual Studio 2010 用 C# 编写的 Windows 服务，目标是完整的 .NET Framework 4.当我从调试版本运行时，服务按预期运行.但是，当我从 Release 版本运行它时，我得到一个 System.BadImageFormatException(详细信息如下).我一直在互联网上寻找解决方案，但到目前为止我发现的每件事都没有帮助我找到解决方案.

该问题存在于 Windows 7 64 位(开发)和 Windows XP SP3 32 位(目标)系统上.

这是我迄今为止尝试过的:

• 经过验证的构建设置(例如 Platform Target)都相同 (x86).
• 将 peverify 与/verbose 选项一起使用以确保程序集二进制文件有效.
• 使用 fuslogvw 查找任何加载问题.
• 使用 CheckAsm 查找丢失的文件或程序集.

所有这些检查都没有改变任何东西.我在下面包含了例外信息的全文，其中一些名称已更改以保护我公司主人的秘密.

解决方案

经过验证的构建设置(例如平台目标)都相同 (x86).

那不是崩溃日志所说的:

<块引用>

程序集管理器加载自:C:WindowsMicrosoft.NETFramework64

注意名称中的 64，这是 64 位版本框架的所在地.在您的 EXE 项目上设置目标平台设置，而不是您的类库项目.XxxDevicesService EXE 项目决定了进程的位数.

I have a Windows service written in C# using Visual Studio 2010 and targeting the full .NET Framework 4. When I run from a Debug build the service runs as expected. However, when I run it from a Release build I get a System.BadImageFormatException (details below). I've been searching the internet for a solution but so far every thing I've found hasn't helped me find a solution.

The problem exists on both Windows 7 64-bit (dev) and Windows XP SP3 32-bit (target) systems.

Here is what I've tried so far:

• Verified build settings such as Platform Target are all the same (x86).
• Used peverify with the /verbose option to ensure the assembly binaries were valid.
• Uses fuslogvw to look for any loading issues.
• Used CheckAsm to look for missing files or assembiles.

All of these checks didn't change anything. I've included the full text of the exception information below, with some of the names changed to protect the secrets of my corporate masters.

解决方案

Verified build settings such as Platform Target are all the same (x86).

That's not what the crash log says:

Assembly manager loaded from: C:WindowsMicrosoft.NETFramework64

Note the 64 in the name, that's the home of the 64-bit version of the framework. Set the Target platform setting on your EXE project, not your class library project. The XxxDevicesService EXE project determines the bitness of the process.
