Connecting to the Database

To connect to your newly created SQLite database, use the following code:

using Devart.Data.SQLite; class Program {     static void Main(string[] args)     {         string connectionString = "Data Source=myDatabase.sqlite;Version=3;";         using (SQLiteConnection connection = new SQLiteConnection(connectionString))         {             connection.Open();             Console.WriteLine("Connection to database established successfully.");         }     } } 

Executing SQL Commands

With the connection established, you can execute SQL commands to create tables, insert data, and query the database. Here’s an example of how to create a table and insert data:

using Devart.Data.SQLite; class Program {     static void Main(string[] args)     {         string connectionString = "Data Source=myDatabase.sqlite;Version=3;";         using (SQLiteConnection connection = new SQLiteConnection(connectionString))         {             connection.Open();             // Create a table             string createTableQuery = "CREATE TABLE IF NOT EXISTS Users (Id INTEGER PRIMARY KEY, Name TEXT)";             using (SQLiteCommand command = new SQLiteCommand(createTableQuery, connection))             {                 command.ExecuteNonQuery();             }             // Insert data             string insertQuery = "INSERT INTO Users (Name) VALUES ('John Doe')";             using (SQLiteCommand command = new SQLiteCommand(insertQuery, connection))             {                 command.ExecuteNonQuery();             }             Console.WriteLine("Table created and data inserted successfully.");         }     } } 

Querying Data

To retrieve data from the database, you can use the following code:

using Devart.Data.SQLite; class Program {     static void Main(string[] args)     {         string connectionString = "Data Source=myDatabase.sqlite;Version=3;";         using (SQLiteConnection connection = new SQLiteConnection(connectionString))         {             connection.Open();             string selectQuery = "SELECT * FROM Users";             using (SQLiteCommand command = new SQLiteCommand(selectQuery, connection))             {                 using (SQLiteDataReader reader = command.ExecuteReader())                 {                     while (reader.Read())                     {                         Console.WriteLine($"Id: {reader["Id"]}, Name: {reader["Name"]}");                     }                 }             }         }     } }
