无法打开使用asp.net MVC3应用程序数据库（源码）spring.net(Unable to

我正在写一个asp.net MVC3 Web应用程序。我想使用SQLite数据库。不幸的是，我得到一个SqliteException说“无法打开数据库”。

Spring的版本：1.3.2
NHibernate的-版本：3.2

DbProvider / ConnectionString的：

<db:provider id="employeesDbProvider"
           provider="SQLite-1.0.72"
           connectionString="Data Source=.\Database\Employees.db3;Version=3;">
</db:provider>

堆栈跟踪：

bei System.Data.SQLite.SQLite3.Open(String strFilename, SQLiteOpenFlagsEnum flags, Int32 maxPoolSize, Boolean usePool) in c:\dev\sqlite\dotnet\System.Data.SQLite\SQLite3.cs:Zeile 239.
bei System.Data.SQLite.SQLiteConnection.Open() in c:\dev\sqlite\dotnet\System.Data.SQLite\SQLiteConnection.cs:Zeile 1022.
bei NHibernate.Connection.DriverConnectionProvider.GetConnection()

我甚至尝试将DataSource设置为一个绝对路径（C：\ TEMP \数据库\ Employees.db3），但同样SqLiteException被抛出。

更新：

错误页面上显示的堆栈跟踪：

我做了一个快速测试使用SQLite，Spring.Net和它失败了同样的错误，但是当我用斜杠，而不是反斜杠奇迹般地开始工作连接的字符串中。

<db:provider id="employeesDbProvider" 
    provider="SQLite-1.0.72"
    connectionString="Data Source=c:/temp/Database/Sample.db3;Version=3;">
</db:provider>

编辑：我测试了一下再找出该文件，如果我用点前缀，例如，存储./Employees.db3 。在IISExpress它被保存在C:\Program Files (x86)\IIS Express最有可能不是你所期望没有。

在IIS7它只是失败，出现Unable to open the database file错误，ihmo因为它试图写入Temporary ASP.NET Files夹。

最安全的办法是使用

<db:provider id="employeesDbProvider" 
    provider="SQLite-1.0.72"
    connectionString="Data Source=|DataDirectory|Sample.db3;Version=3;">
</db:provider>

至极是App_Data的MVC应用程序的文件夹中。

我使用的SQLite 1.0.80.0对我的测试。请记住，SQLite不创建目录，需要ACL写权限。
