在.net 4.0中使用SQLite的内存数据库

在app.config中修改:

  <startup useLegacyV2RuntimeActivationPolicy="true">

    <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.0" />

  </startup> 

然后: 

        Dim SQLconnect As New SQLite.SQLiteConnection()

        Dim SQLcommand As SQLiteCommand

        SQLconnect.ConnectionString = "Data Source=:memory:;Version=3;New=true"

        SQLconnect.Open()

        SQLcommand = SQLconnect.CreateCommand

        SQLcommand.CommandText = "CREATE TABLE foo(title TEXT, description TEXT)"

        SQLcommand.ExecuteNonQuery()

        SQLcommand.CommandText = "INSERT INTO foo (title, description) VALUES ('This is a title', 'This is a Description')"

        SQLcommand.ExecuteNonQuery()

        SQLcommand.CommandText = "SELECT * FROM foo"

        Dim SQLreader As SQLiteDataReader = SQLcommand.ExecuteReader()

        While SQLreader.Read()

            MessageBox.Show(SQLreader.Item(0).ToString)

        End While

        SQLcommand.Dispose()

        SQLconnect.Close()
