this SharpDevelop web site
. The conversion result may not be perfect, but it shows how to make API calls.
is another tool that can help translate the code. Simply open our C# version samples (exe or dll) and check the disassembled code.
The good news is that VB.NET samples are added in 5.0 release.
Is there a class reference?
Answer: Help packages (both CHM and Help2 versions) are available in binary release packages. You can also build them from source code.

Non standard devices can lead to various issues, and below are the ones reported back by users,
It is not a complete list but should shed some light on how to troubleshoot and locate the culprit. You will have to modify #SNMP to adapt to those problems on your own.
What's the current version and previous versions?
Answer: Please refer to our
Why should I use this library?
Answer: It is hard to explain.
On one hand, there are indeed a lot of commercial packages available throughout the market. However,
shows that most of them are too expensive and a few of them only provides limited functions a developer may need.
On the other hand, there are few open source packages existing on .NET platform. For example, I cannot compile SNMP++.NET successfully and I don't think that library provides a natural enough API interface.
Could I contribute to this project?
Answer: Welcome. You can do a lot to help even if you may not have the chance and ability to contribute patches and new functions.
Here are a list of items I expect,
- Comments on the API, such as "this part of API is not natural enough. We need to change it to blah blah blah and then it is more natural".
- Bug reports, such as "it does not work in my case. What's up then"?
- Patches, such as "I found a bug and created a patch to fix it, so please merge it into the repository". I am more than glad to hear from you.
- New functions, such as "why not implement something like this".
