emptying a folder using SSIS script task

Hi Guys,

I am generating reports to a directory (folder), via ssis script task and C#.. I want to validate the following..

1. Deleting all old reports except last 10 reports. My report name for example is Report_DDMMYYYY

2. If current report already exists then I want to overwrite that report every time if i run the ssis script task (which exists in a foreach loop container) manually.

I am using Streamwriter to dump the data into a flatfile report.

Thanks.
