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()
