Are you referring to a way to execute small C# code statements and have
them executed as if they were within a simple program, on the fly?
Because if so, then you can use the classes and methods within
System.CodeDom, specifically within System.CodeDom.Compiler, to compile
and execute code. So you can take a command such as
"string.Compare("test","testing")" from a prompt, build it up into a
simple class with an entry point, use an ICodeCompiler object (which one
depends on which language) to compile the code, and then execute the
assembly in memory, returning the result back to the prompt (without
saving any of the code or binary assembly to file, truly on the fly).
This leaves you with a basic eval prompt for running simple statements,
in whatever .Net language you choose to support using different
ICodeCompiler's. You could ofcourse get as complicated as you like in
building up the program to execute, depending on how much information
you want to let the user enter straight from the command line, from
simple statements to full code blocks.
I have actually started working on a DotNet/Mono written shell named
xSh, for both Windows and Linux, and one of the plugins I'm going to
incorporate will be a simple C# code evaluator for running simple
functions and simple bits of code off the command line. I hope to have a
beta release out fairly soonish.
If this was what your after and you'd like more info, or a code sample,
just let me know.
Oh and if I'm way off base and this isn't what you wanted... then ignore
my ramblings :-)
