3. Now we have to create Database in SQL Server Management Studio. To create a database and table in SQL Server Database, open SQL Server application, and Right click over Database and then click new, give the database name whatever you want and click OK. After then expand that Database directory which you can see in the left pane of the SQL Server Studio Software and expand that Database directory and then expand your recently created Database. And then you will see Table directory. Right click that Table Directory click on Table and click OK. You will see the new window which looks like following picture after filling the column name and selecting the datatype:

save that table by pressing ctrl+s and give the table name whatever you want.

4. We need to connect our application to the database for this, click on the Server Explore which is in the right side of the Toolbox in the left pane of your visual studio. And then right click on the Data Connection>Add connection. New window will appear select your Data Source; in our Case Data Source is Microsoft SQL Server. To do this click on change and select Microsoft SQL Server, Click OK. And then New window will appear, select your Server Name your Database Name and click OK.

5. Double click on register button to go to the .cs section of your project and scroll up and then add the following namespace to your program as:

using System.Data;
using System.Data.SqlClient;

6. Now write the following code inside the clicking event of the register button.

SqlConnection con = new SqlConnection("Data Source=RAN-PC;Initial Catalog=userregcs;Integrated Security=True");
            SqlCommand cmd = new SqlCommand(@"INSERT INTO [dbo].[register]
           ([firstname]
           ,[lastname]
           ,[address]
           ,[gender]
           ,[email]
           ,[phone]
           ,[username]
           ,[password])
     VALUES
           ('" + txtFname.Text + "', '" + txtLname.Text + "', '" + txtAdd.Text + "', '" + cmbGender.SelectedItem.ToString() + "', '" + txtEmail.Text + "', '" + txtPhone.Text + "', '" + txtUser.Text + "', '" + txtPass.Text + "')", con);
            con.Open();
            cmd.ExecuteNonQuery();
            con.Close();
            MessageBox.Show("Register Successfully");

NOTE: Change this code in your context (because your connection string (Data Source=RAN-PC;Initial Catalog=userregcs;Integrated Security=True) is different than mine)

7. Run your project by click the green triangular button in any browser, fill the form and click that register button, you will get the successful message. That’s it.
