SOAP客户端代码中的BadImageFormatException [英] BadImageFormatException from SOAP client code

问题描述

许多在OS(例如32位Windows XP)上运行.NET 4 SOAP客户端的站点都报告了以下示例.

A number of sites running a .NET 4 SOAP client, on OS's such as Windows XP 32-bit, are reporting exeptions like the one below.

我们无法始终如一地复制它.它仅在数千个站点中的3个或4个站点上发生过.有人知道与此相关的任何已知问题吗?有没有解决方法?我们尝试过多次重新安装.NET.

We can't reproduce it consistently. It has only happened on 3 or 4 sites out of thousands. Does anyone know of any known issue that might relate to this? Is there a workaround? We've tried reinstalling .NET a number of times.

推荐答案

这似乎与处理器体系结构有关.我的意思是，我认为您已经在任何CPU"(模式将在32位系统中以32位模式运行，在64位计算机中以64位模式运行.但是，我猜您的应用程序使用了一些dll 是为特定的CPU体系结构(x86或x64但不是AnyCPU)构建的.对于实例，如果您的任何dll是针对x86模式构建的(这意味着它包含32位指令)，则该dll无法在64位计算机.

It looks to be an issue with the processor architecture. I mean, I think you have built your code in "Any CPU" mode which will run in 32 bit mode in 32 bit systems and in 64 bit mode in 64 bit machines. But, I guess, your application uses some dll which is built for specific CPU architecture (either x86 or x64 but not AnyCPU). For instance, if any of your dll is built against x86 mode (which means it contains 32 bit instructions) then, the dll cannot be executed in 64 bit machines.

因此，检查是否有任何dll(尤其是COM dll)具有特定于32位计算机的指令.如果是，则需要在x86模式下编译应用程序.这样，当您启动应用程序时，默认情况下会启动32位进程.而你的32位 dll可以正常运行.

So, Check whether any dll (especially a COM dll) has instructions specific to 32 bit machines. If yes, then you need to compile your application in x86 mode. By this, when you start your application, by default 32 bit process is started. And your 32 bit dll will run without any issues.

我希望这会有所帮助.
