    UPDATED - 2: 

    I have added three new files for saving file in database. 

    • App_Code  
      1. SaveFile.cs  (Logic for saving file database, Attention: modify only database connection)
      2. Result.cs (this will return status success of failed with description)
    • App_Data 
      1. Script.Sql (Database script for creating Table and Stored Procedure) 

    Modified only one file UploadEngine.aspx.cs

    Please add following code after

    if (this.fileUpload.PostedFile != null && this.fileUpload.PostedFile.ContentLength > 0) 
    //START : Saving File in Database
                   SaveFile saveFileInDB = new SaveFile();
                   saveFileInDB.FileName = this.fileUpload.PostedFile.FileName;
                   saveFileInDB.FileExtension = Path.GetExtension(this.fileUpload.PostedFile.FileName);
                   saveFileInDB.FileContent = this.fileUpload.FileBytes;
                   Result Result = saveFileInDB.SaveFileInDB();
                   if (Result.IsError == false)
                   {
                       //File Save in Database Successfully!
                   }
                   else
                   {
                       //Error in Saving File in Database!
                       //Error: Result.ErrorMessage
                       //InnerException: Result.InnerException
                       //StackTrace: Result.StackTrace
                   }
                   //END : Saving File in Database
