Image uploading using Asp.net to MS sql server by c# is very easier.Here i will show how to convert an image to binary data and reduce the image size and then upload the binary data to MS sql server.

Create the Database structure

In the database we have to declare the image id, image name and image binary data.

name type
imageId int identity not null
imageName varchar(100)
imageBinaryData image

if we declare the imageBinaryData as image means.we can convert our image to binary data and the upload to the sql server is easier.


In the New Web Form page drag and drop the Fileupload control and name it as FileUpload and a button control as btnSubmit.

Write the logic for file upload and resize the image in .cs file

use the Name space on the top of the namespace declaration.

using System.Drawing;
using System.Drawing.Imaging;
using System.IO;
using System.Text;

then declare the sql connection before the page load event.

SqlConnection Conn = new SqlConnection(“server=.;database=sample;Integrated Security=True”);

in the button click event
//Check the file upload is having some data.
if (FileUpload.FileName != “”)
{
System.Drawing.Image image = System.Drawing.Image.FromStream(FileUpload.PostedFile.InputStream);
int imgHeight, imgWidth;
imgHeight = 130;
imgWidth = 150;

///….
}

I will attach the sample Image upload File with this.
