我的Visual Studio 2010解决方案包括一个C DLL和C#项目，其中C#项目调用C DLL。 在32位Windows 7 Pro计算机上构建解决方案时运行正常。 但是在64位Windows 7 Pro上构建也没有问题，但运行时，C#调用DLL中的函数时会报错：
A first chance exception of type 'System.BadImageFormatException'
解决方案配置管理器的设置如下：
<DLL project> Platform = Win32 (<<< no option to change to "Any CPU")
<C# project> Platform = "Any CPU"
下面的输出是：
