How to Use and Connect To Sqlite in a Windows Application

Here I will explain how to use and connect to Sqlite in a Windows application.

Why we use Sqlite in C#

We use Sqlite because all ther other databases that we use generally require a server and Sqlite is a database that we can embed within our system. So we don't require any server for a Sqlite database. Most of mobile and small databases don't require a server and if we want to make a standalone application for one computer that doesn't depend on another server then Sqlite is perfect for us.

For more information about Sqlite you can go to this link: Sqlite.

How to connect Sqlite with C#. Basically C# doesn't support Sqlite itself so we need a third-party DLL to connect to a Sqlite database.

There is a link,  from this link you can get a DLL file link and at this link you go to the download section and download the latest version. The download first link is a ZIP file so you extract this file to your application in the debug folder.

Step 1: Select a new project

Open your Visual Studio and select new project and in Visual C# select "Windows Forms Application" and provide the name as Sqlite and click on OK.

Step 2: Extract DLL file

Right-click on your application and select "Open folder in your window application" and then go to:

BIN -> Debug and extract your application here.

After this again right-click on your application and select "Add reference" and go to:

Browser -> BIN -> Debug and select DLL file (Sqlite Net.dll).

Step 3: Form

Drag and drop a button and provide the name as "connect Sqlite".

Step 4: Code

Double-click on the button and write the following code.

Add a namespace

using Finisar.SQLite;

You use sample code from this link:

using System;

using System.Collections.Generic;

using System.ComponentModel;

using System.Data;

using System.Drawing;

using System.Text;

using System.Windows.Forms;

using System.Data.SqlClient;

using System.Text;

using System.IO;


namespace First_Csharp_app


    public partial class Form1 : Form


        public Form1()




        private void Choose_Btn_click(object sender, EventArgs e)


            // [snip] - As C# is purely object-oriented the following lines must be put into a class:


            // We use these three SQLite objects:

            SQLiteConnection sqlite_conn;

            SQLiteCommand sqlite_cmd;

            SQLiteDataReader sqlite_datareader;


            // create a new database connection:

            sqlite_conn = new SQLiteConnection("Data Source=database.db;Version=3;New=True;Compress=True;");


            // open the connection:



            // create a new SQL command:

            sqlite_cmd = sqlite_conn.CreateCommand();


            // Let the SQLiteCommand object know our SQL-Query:

            sqlite_cmd.CommandText = "CREATE TABLE test (id integer primary key, text varchar(100));";


            // Now lets execute the SQL ;D



            // Lets insert something into our new table:

            sqlite_cmd.CommandText = "INSERT INTO test (id, text) VALUES (1, 'Test Text 1');";


            // And execute this again ;D



            // ...and inserting another line:

            sqlite_cmd.CommandText = "INSERT INTO test (id, text) VALUES (2, 'Test Text 2');";


            // And execute this again ;D



            // But how do we read something out of our table ?

            // First lets build a SQL-Query again:

            sqlite_cmd.CommandText = "SELECT * FROM test";


            // Now the SQLiteCommand object can give us a DataReader-Object:

            sqlite_datareader = sqlite_cmd.ExecuteReader();


            // The SQLiteDataReader allows us to run through the result lines:

            while (sqlite_datareader.Read()) // Read() returns true if there is still a result line to read


                // Print out the content of the text field:

                //System.Console.WriteLine( sqlite_datareader["text"] );


                string myreader = sqlite_datareader.GetString(0);



            // We are ready, now lets cleanup and close our connection:





Step 5: Output

Run your application and click on the button.


Step 6: Database

Now if you again right-click on your application and select "Open folder in your window application" and then go to:

BIN -> Debug then here you will see the database so for Sqlite there is no need for a server.

Step 7: Database Table

If you want to see this database then there is a simple way to see the table and everything in the database then go to Mozila and click at the above and go to "Add-ons".

And at the search type "Sqlite" here you will see "Sqlite Manager 0.7.7 " then install this.
Sqlite Manager

After installation go again to the top at Mozila and there click on "web developer -> Sqlite Manager".

Here you go to the button (open) and browse your database then you will see the table in your database.
