Fetch Image From Database in Windows Form Application

Introduction

In my previous article I described how to insert image into database and in this article I will describe how to retrieve an image from a database and display it in a picture box. 

Use the following procedure to fetch the image.

Step 1

Open a Windows Forms application and insert a picture box and a button into the form.

Step 2

Write C# code to retrieve the image from the SQL Server database .

using System;

using System.Collections.Generic;

using System.ComponentModel;

using System.Data;

using System.Drawing;

using System.Linq;

using System.Text;

using System.Windows.Forms;

using System.Data.SqlClient;

using System.IO;

 

namespace insert_image_in_database

{

    public partial class Form2 : Form

    {

        public Form2()

        {

            InitializeComponent();

        }

        SqlConnection con;

        SqlCommand cmd;

        private void button1_Click(object sender, EventArgs e)

        {

            con = new SqlConnection("Data Source=MCNDESKTOP03;Initial Catalog=pulkit;User ID=sa;Password=wintellect@123");

            con.Open();

            cmd = new SqlCommand("select picname from pic where id=2", con);

            SqlDataAdapter da = new SqlDataAdapter(cmd);

            DataSet ds = new DataSet();

            da.Fill(ds);

            if (ds.Tables[0].Rows.Count > 0)

            {

                MemoryStream ms = new MemoryStream((byte[])ds.Tables[0].Rows[0]["picname"]);

                pictureBox1.Image = new Bitmap(ms);

            }

        }

    }

}

 

 Step 3

Now run your application and click on the button to see the image displayed in the picture box.
