VB.Net Error object in C#

Question

I don't think there is a good way to do this...

but I have a vb.Net DLL which has an error handling method. Its good, and I want to use it in my C#.Net site.

So I add the vb.Net DLL to my C# project.

But wait! My vb.Net error handler method requires a 'Microsoft.VisualBasic.ErrObject' !

Hmm.. is it possible to create such a data type in C#? Even by some type of conversion?

Or is this just ugly and should I forget about even trying something so outrageous and just restart the project in vb.Net?

*note that I am not going to change the required data type in the DLL

Thanks!

You can add a reference to the Microsoft.VisualBasic dll to your C# project.

Right-click the References in the solution explorer click Add Reference,then search for Microsoft.VisualBasic:

But in general i would suggest to use the .NET error handling with exceptions that inherit from or are System.Exception and support using try-catch-finally.

Yes this allows you to create the object :) thank you! But to do a try-catch with this still causes a problem because you have to catch an object derived from System.Exception

@Christopher: good point, added it to my question. But OP hasn't mentioned that he wants to use try...catch. However, never used VisualBasic.ErrObject in VB.NET or C# so no idea if it works at all.

if you mean errors generated by Err.Raise vb method, such error can be distinguished by theException.TargetSite.DeclaringType (the fact that it is System.Exception still is PITA, as written by Christopher before)
