C＃.NET和Win2012防火墙

Question

I'm not that advanced with C# and need some assistance compiling a code. Honestly it's first time I'm doing that. I have a code that is aimed to automatically block rdp bruteforce. Here is acode I'm trying to compile: https://pastebin.com/CJEapWyi

I've got problems interacting with firewall api. In the internet people say I have to add reference to FirewallAPI.dll and I'm compiling code using following CLI:

    c:\Windows\Microsoft.NET\Framework\v4.0.30319>csc.exe /r:"c:\windows\system32\FirewallApi.dll" c:\Users\Administrator\Documents\rdpbrute.cs

and it says:

error CS0006: Metadata file 'FirewallApi.dll' could not be found

Is there any way to compile a program that interacts with firewall using this compiler or I have to install visual studio?

Thanks for your time.

Answer 1

Instead of referencing c:\\windows\\system32\\FirewallApi.dll you should first create COM interop library Interop.FirewallApi.dll and then add reference to it.

Interop library can be created with use of tlbimp.exe tool that is part of Visual Studio installation. A more simple approach is to use Add reference feature inside of VS (just select c:\\windows\\system32\\FirewallApi.dll and interop library will be created automatically).

So you have to install VS as you suggested.
