What causes System.BadImageFormatException when constructing System.Data.SQLite.SQLiteConnection
提问by Tim Murphy
I've broken the code down to the smallest possible statement:
我已将代码分解为尽可能小的语句：
Dim cn As System.Data.SQLite.SQLiteConnection
And I get the following error when calling the code from a WinForm applicaiton:
从 WinForm 应用程序调用代码时出现以下错误：
System.BadImageFormatException: Could not load file or assembly 'System.Data.SQLite, Version=1.0.65.0, Culture=neutral, PublicKeyToken=db937bc2d44ff139' or one of its dependencies. An attempt was made to load a program with an incorrect format. File name: 'System.Data.SQLite, Version=1.0.65.0, Culture=neutral, PublicKeyToken=db937bc2d44ff139'
System.BadImageFormatException：无法加载文件或程序集“System.Data.SQLite，版本=1.0.65.0，Culture=neutral，PublicKeyToken=db937bc2d44ff139”或其依赖项之一。试图加载格式不正确的程序。文件名：'System.Data.SQLite，版本=1.0.65.0，文化=中性，PublicKeyToken=db937bc2d44ff139'
Yet calling the same piece of code from MS Unit Test I do not get the error, plus the full code set works as expected.
然而，从 MS 单元测试调用同一段代码我没有得到错误，加上完整的代码集按预期工作。

SqlLite contains unmanaged code, you can't run it on a 64-bit operating system unless you deploy the 64-bit version. Quick fix: Project + Properties, Build tab, Platform Target = x86.
SqlLite 包含非托管代码，您不能在 64 位操作系统上运行它，除非您部署 64 位版本。快速修复：项目 + 属性，构建选项卡，平台目标 = x86。

Make sure you use correct assembly with respect to 32 and 64 bits.
确保针对 32 位和 64 位使用正确的程序集。

I solved the problem by downloading a new version of the SQLite DLL via NuGet: http://gurustop.net/blog/2011/05/19/sqlite-database-nuget-package-common-problems-solved/
