using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;

    public Form1()
    {
        InitializeComponent();
    }
   public SqlConnection con = new SqlConnection(@"Place Your connection string");
            
           private void Savebutton_Click(object sender, EventArgs e)
    {
         SqlCommand cmd = new SqlCommand("insert into  Data (Name,PhoneNo,Address) values(@parameter1,@parameter2,@parameter3)",con);
                cmd.Parameters.AddWithValue("@parameter1", (textBox1.Text));
