私はasp.netmvc3Webアプリケーションを書いています。sqliteデータベースを使用したい。残念ながら、「データベースを開くことができません」というSqliteExceptionが発生します。

春バージョン：1.3.2

NHibernate-バージョン：3.2

DbProvider / Connectionstring：

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

スタックトレース：

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()

DataSourceを絶対パス（C：\ temp \ database \ Employees.db3）に設定しようとしましたが、同じSqLiteExceptionがスローされます。

アップデート：

SQLite、Spring.Netで簡単なテストを行ったところ、同じエラーで失敗しましたが、接続文字列でバックスラッシュの代わりにスラッシュを使用すると、魔法のように機能し始めます。

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

編集： ドットプレフィックスを使用した場合、ファイルが保存されている場所を見つけるためにもう少しテストしました./Employees.db3。IISExpressでは、C:\Program Files (x86)\IIS Expressほとんどの場合、期待したものとは異なる状態で保存されます。

IIS7ではUnable to open the database file、フォルダに書き込もうとするため、ihmoというエラーで失敗しTemporary ASP.NET Filesます。

最も安全な賭けは使用することです

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

Wichは、App_DataMVCアプリケーションのフォルダーです。

テストにはSQLite1.0.80.0を使用しました。SQLiteはディレクトリを作成せず、ACL書き込み権限が必要であることに注意してください。
