using SSIS script task to send email result

sometimes notification email is required to be sent so that receivers can know about the data load status. Following C# code in SSIS script task is composed to meet the requirement.

1. drag a SQL task to get data result and assigned full set to an object variable(e.g.oCompleteFileList)

2. drag a script task to compose HTML message body and send email
