.net - 如何使用 .Net 创建 Berkeley 数据库？

Question

我正在使用以下代码创建 Berkeley DB，但我在最后一行收到错误:

The type initializer for 'BerkeleyDB.Internal.libdb_csharpPINVOKE' threw an exception.

代码:

Dim DB As DatabaseEnvironment
Dim Config As DatabaseEnvironmentConfig

Config = New DatabaseEnvironmentConfig
Config.Create = True

DB = DatabaseEnvironment.Open("d:\database.db", Config)

有谁知道我做错了什么吗？

我正在使用 VB Express 2010 和 .Net Framework 4.0

1. 确保您的 .net 项目设置为 .NET 4.0
2. 构建为 x86
3. libdb_csharp61.dll 在您的/bin/debug 文件夹中
