C#调用dll提示"试图加载格式不正确的程序"解决方法
程序在32位操作系统上运行正常，在64位操作系统上运行读卡功能提示”试图加载格式不正确“。
程序在64位操作系统上运行正常，在64位操作系统上运行读卡功能提示”试图加载格式不正确“。
--------------------------------------------------------------------------------------------
点击项目属性，把目标平台Any CPU 设置为X86（32位操作系统）或者X64（64位操作系统）
按照上面解决方案可能会有下面的问题：
C# form继承问题 ： 提示 无法加载基类 ；请确保已引用该程序集并已生成所有项目。
把 生成 - 目标平台 改成 x86或者Any CPU ，重新生成一次，Form可正常编辑。
所以新的解决方案是：选择Any CPU 把下面打勾的去掉
