"Ngoại lệ cơ hội đầu tiên của loại 'System.BadImageFormatException'" sau khi xây dựng trên máy tính 64 bit

Question

Giải pháp Visual Studio 2010 của tôi có dự án C DLL và C#, gọi là C DLL. Giải pháp hoạt động tốt khi được xây dựng trên máy tính Windows-7 Pro 32-bit. Ngày 64-bit Windows 7 Pro, xây dựng ổn, nhưng khi chạy, C# gọi hàm trong DLL và bị lỗi:

A first chance exception of type 'System.BadImageFormatException' 

thiết lập giải pháp Virtual Machine Manager là:

<DLL project> Platform = Win32  (<<< no option to change to "Any CPU") 
<C# project> Platform = "Any CPU" 

Kết quả dưới đây là:

1. C DLL BUILD OUTPUT

2. C# BUILD OUTPUT

3. RUN OUTPUT

Answer 1

Loaded 'C:\Windows\Microsoft.Net\assembly\GAC_64\mscorlib...

chương trình bạn đang chạy như một quá trình 64-bit. DLL của bạn chứa mã không được quản lý 32 bit. Kaboom.

Bạn sẽ cần buộc EXE chạy dưới dạng quy trình 32 bit để có thể tải tệp DLL. Nhấn chuột phải vào dự án EXE của bạn trong cửa sổ Solution Explorer. Thuộc tính, tab Xây dựng, thay đổi cài đặt Nhắm mục tiêu nền tảng từ AnyCPU thành x86. Trên VS2012 và chọn tùy chọn "Ưu tiên 32 bit". Lặp lại cho cấu hình Release.
