C#呼叫dll提示"試圖載入格式不正確的程式"解決方法

程式在32位作業系統上執行正常，在64位作業系統上執行讀卡功能提示”試圖載入格式不正確“。

程式在64位作業系統上執行正常，在64位作業系統上執行讀卡功能提示”試圖載入格式不正確“。

--------------------------------------------------------------------------------------------

點選專案屬性，把目標平臺Any CPU 設定為X86（32位作業系統）或者X64（64位作業系統）

按照上面解決方案可能會有下面的問題：

所以新的解決方案是：選擇Any CPU 把下面打勾的去掉
