Respected

I am developing a module in asp.net. Where a user submits a picture using fileupload control to the server. At server i Have to create image of the posted file without saving it on server. Then i have to save it to sql server database not on server. So help is needed

To Some Extent I have coded some of the portion but the major portion is to be done

C#

Stream fi = FileUpload1.PostedFile.InputStream;
var ext = FileUpload1.PostedFile.ContentType;
var imageOrNot = ext.Contains("image") ? true : false;

if (imageOrNot)
{
      byte[] imagearr = new byte[fi.Length];
      fi.Read(imagearr, 0, (int)fi.Length);
      fi.Close();
      Response.Write(imagearr);
      MemoryStream ms = new System.IO.MemoryStream(imagearr);
      System.Drawing.Image imgTemp = System.Drawing.Image.FromStream(ms);
 
     FileStream fs = File.OpenRead(FileUpload1.PostedFile.FileName);
     //byte[] ba = new byte[fs.Length];
     //int length = fs.Read(ba, 0, ba.Length);

Thanks in Advance

Letz assume DB field name is EmployeeImg with image attribute of SQL Server. Code will be:

C#

SqlConnection connection = null;
  try
  {
      FileUpload img = (FileUpload)imgUpload;
      Byte[] imgByte = null;
      if (img.HasFile && img.PostedFile != null)
      {
          HttpPostedFile File = imgUpload.PostedFile;
          imgByte = new Byte[File.ContentLength];
          File.InputStream.Read(imgByte, 0, File.ContentLength);
      }
      string conn = ConfigurationManager.ConnectionStrings["EmployeeConnString"].ConnectionString;
      connection = new SqlConnection(conn);

      connection.Open();
     string sql = "INSERT INTO EmpDetails(EmployeeImg) VALUES(@EmployeeImg)";
      SqlCommand cmd = new SqlCommand(sql, connection);
      cmd.Parameters.AddWithValue("@EmployeeImg", imgByte);
      int id = Convert.ToInt32(cmd.ExecuteScalar());
  }
