I'm writing C# 2005 Express Addition, Dot Net Framework(2.0 or 3.0).
But i think if you've idea about c# then you might be able to complete it.


//Have DataAdapter.
{
  OracleDataAdapter pAdapter = new OracleDataAdapter("Select * from Employee", con);
}

//Have Dataset
{
  DataSet pDataSet = new DataSet("Employee");
}

//Fill Dataset.
{
 pAdapter.Fill(pDataSet, "Employee");
}

0).Have a New Row in Dataset.
{
 DataRow pRow = pDataSet.Tables["Employee"].NewRow();
}

1). Load the path of Image that you want to store in Oracle(9i)database.
{
 if (strImageName1 != "")
    {
    //Read Access to the file chosed by 'Browse' button.
    FileStream fs = new FileStream(@strImageName1, FileMode.Open, FileAccess.Read);
    }
}

2). Convert it into Stream of data and keep it into an Array of byte.
{
 //Create a byte array of file stream length
 byte[] ImageData = new byte[fs.Length];
}

3).
{
 //Read block of bytes from stream into byte array
 fs.Read(ImageData, 0, System.Convert.ToInt32 fs.Length));
 fs.Close();
}

4). Save this stream into your database.
{
 //Assigning the byte array containing image data.
 pRow["Emp_image"] = ImageData;
}

5). Don't Forget to Add Row into datase.
{
 pDataSet.Tables["Employee"].Rows.Add(pRow);
}

6). Don't forget to Update DataAdapter.
{
 pAdapter.Update(pDataSet, "Employee");
}

I Hope it works.
If still not clear, don't hesitate to e-mail me.

Mr.Khurram
