Centralized Error Capture and Messaging

I'm using SSIS 2012. I'm trying to collect all package errors as a formatted string, and communicated those from an OnError event (at the control flow level) as an email.

I have found examples here:

The only problem is, these examples are in vb.net. I haven't found anything like this done in C#.

How can I implement these same solutions in C#?

The script task I am writting is configured for .NET 4.0

Thanks.
