SQL Server Database Connection in Windows Forms

I will start this (the first) tutorial by showing how to create a SQL Server database connection. Here I will explain step-by-step. Use the following procedure.

Step 1: Create a Windows Forms Form

Open Visual Studio and create a new project and select Windows Forms application and provide it the name "First_Csharp app".

Step 3: Database table

Create a database table in SQL Server. Here the database name is "windowapp" and "tablename" is the data.

Step 4:
Code for button click.

First insert a namespace "using System.Data.SqlClient".

using System.Collections.Generic;

using System.ComponentModel;

using System.Data;

using System.Drawing;

using System.Text;

using System.Windows.Forms;

using System.Data.SqlClient;


namespace First_Csharp_app


    public partial class Form1 : Form


        public Form1()





        private void button1_Click(object sender, EventArgs e)




                String str = "server=MUNESH-PC;database=windowapp;UID=sa;password=123";

                String query = "select * from data";

                SqlConnection con = new SqlConnection(str);

                SqlCommand cmd = new SqlCommand(query, con);


                DataSet ds = new DataSet();

                MessageBox.Show("connect with sql server");
