Is it possible to run C++ or C codes from a file C#

Yes, it is possible.

No it isn't practical without a fair amount of work.
You could do it by using an existing C/C++ compiler of compile the code, link it, and run teh rsulting executable, but frankly it's a nuisance job, and kinda messy, particularly if there are any errors in teh source, or you want to integrate you own values / code into it.

The other solution is to write or find a C/C++ compiler/interpreter on the web and try that - but again, it's a messy job that probably just causes more problems than it solves.

What are you trying to achieve, that you think this is a good idea?
