Which version of C# am I using

Question

I want to find out which version of C# I'm using. If I would be using python I would do something like python -V from the command line, or type:

import sys
print sys.version

In PHP I would do something like this: phpinfo(); in java: java -version

But I was not able to find how to achieve this in C#.

This question does not answer it, although the name suggests that it should.

I got that it depends on the .NET framework, but is there a programmatic way of figuring out my framework? I mean without going to the directory and checking the name of my .NET folders.
