Exception Filter – VB.NET supports this, but not C#, so write a VB.NET wrapper to expose it to C#

Posted by jpluimers on 2011/02/24

Often I explain to people that there are a lot of .NET languages, because the .NET IL is rich, so the individual languages can focus on the IL pieces they do best.

This also means, that most languages have some support for specific pieces of IL that other languages do not have support for.

The IL Exception Filter feature is one such thing. It is supported by for instance VB.NET but not by C# as Junfeng Zhang explains:

C# does not support exception filter. However, VB and IL support it. To add exception filter to C#, we can build a function in VB or IL, then call it in C#.

Read his full article for the complete code.
