Thanks to the dll-files.com, I can download all of them. And put all of them in the same dir with my test exe, it works. Thank you arnaud, you really help a lot.

C# bindings are provided with a visual studio 2010 solution, I think it's better to use it if you can. If you can't (because you have vs2005 or vs2008), please re-create a solution with all C# bindings codes. Be sure you have the dll in your Debug directory : libcurl-4.dll libgcrypt-11.dll libgnutls-26.dll libgpg-error-0.dll libportablexdr-0.dll libtasn1-3.dll libvirt-0.dll libxml2-2.dll Also, be carefull about one thing : these dll must be in the directory of the executable. I mean if you create a project "testBinding" which produce "testBindings.exe", then these dlls must be in the same directory of "testBindings.exe". You can also use "depends.exe" (http://www.dependencywalker.com/) which is a tool used to check dll dependency. You open your libvirt-0.dll with it and see if there is no missing dll (maybe a dll miss you, and I don't see it because my system ever own it, I don't know).

The exception shows libvirt-0.dll cannot be found. I tried to put libvirt-0.dll everywhere. In the same dir with .sln, with .cs file, in Debug dir, even in Windows/System32 dir. But I got no luck. It's still stuck. So I need your help to get me out of the mess. Would you please tell me where I may go wrong?
