How to use Prolog in C #? Swi-prolog

Last month saw Prolog this language, its special grammar attracted me, but after a period of study, I found that it is not as magical as the legend on the Internet, but I am still interested in it, there are predecessors said Prolog itself is not strong, But used as a supplementary language to solve some special problems or very effective, it happens that I am a C #, I looked up how to combine Prolog and C #, but I Baidu came out of the information can only be used to describe the sparse. No way can only Google, the old D's Hosts file is very useful.

Fortunately, as a high-level code farm I will be a little Chinese, thinking of a half-day finally how to use Prolog these words out, and then the magic of Google helped me to give a few options

I can't help but sigh, technology changes the world, code changes the world.

Although my English writing ability is not strong, but reading ability is still possible, found a few posts finally found several solutions, such as P#,swi-prolog and so on.

After a few comparisons, I finally chose swi,http://www.swi-prolog.org/This is its official website, which is a relatively comprehensive help document and so on, and then again a toss to determine the need for the two files, a Swi-prolog installation program, There is also a DLL file, these two files are divided into 32-bit and 64-bit two, first install SWI, and then create a console program, reference SwiPlCs.dll.

Well, the preparation is done, and then the code, I followed the official example to write a code, and then excited to press CTRL+F5 but the result is not the same as I imagined, like this

This is Shenmegui? How is it different from the deal? I hurried to Google search information, sure enough, the foreign great God also has encountered this problem, the official website also has about this error explanation, the wit I rely on solid English Foundation plus browser Web translation function finally understand more than half, probably meaning is not configured environment variable, probably with Java is a reason, So I added swi_home_dir this environment variable, and then continue to run, of course, there is no egg use, is still the above error, then I tried dozens of methods, replaced by 32-bit DLL, installed a win7 virtual machine plus vs2010, installed XP virtual machine plus vs2010, Various methods have tried, the result is still so, toss a few days I almost give up.

Happened to be bored this evening, and Google a bit about this problem, suddenly see this document on the official website http://www.swi-prolog.org/pack/file_details/swicli/doc/introduction-SbsSW.htm

Inside said to add the bin directory to the PATH environment variable, I hold a try to put this sentence in the code

Environment.setenvironmentvariable ("PATH"@ "C:\Program Files\swipl\bin ");

Then Ctrl+f5, then this article is over, mom really can, toss for so long is because of this reason
