推荐答案

BadFormatImageException 是当您的程序针对 32 位架构编译并尝试加载 64 位库时收到的错误，反之亦然.从错误中，您可以参考 log4net(一个众所周知的日志库).
首先，检查您正在创建应用程序的 CPU 类型(x86、x64、AnyCPU)
第二，检查 log4net 的位数(您应该引用相同的应用位数)
第三，检查 IIS 运行的是什么 OS.(如果是 x64 并且您的应用程序是 32，请在应用程序池的高级设置部分将启用 32 位应用程序"设置为 true)

BadFormatImageException is the error that you receive when your program is compiled for a 32bit architecture and will try to load a 64bit library or viceversa. From the error, you have a reference to log4net (a well known log library).
First, check for what kind of CPU you are creating your application (x86, x64, AnyCPU)
Second, check the bitness of log4net (You should reference the same bitness of your apps)
Third, check on what OS IIS is running. (if is x64 and your app 32, set 'Enable 32-bit Applications' to true in the advanced settings section of the application pool)
