Hi
Can anyone tell how we can create our own compiler using C#.NET through which I can execute any program?

Did you try doing any research at all?

Hi wes

Yes i did some rsearch and foud some useful, but i am not able to understand how its working. Take a look at the below link

Why? What possible reason would I need to go look at that? Even if we knew what is was that you are unable to understand, we cannot possibly explain to you how to create a compiler in a forum posting. There is tons and tons of information about this very subject out there, you just need to go look for it. Come back here if you have a specific question about a specific error or line of code.

Is that not a bit too ambitious for your level at this moment?

Do i hv to w8 for sumthing????

Nelek 13-Apr-14 11:36am

To wait, to wait... not

But to work on your own... yes.

That is a project where you will need to search for information, do tests, get errors, do more tests, maybe solve one thing just to find out 3 more are not working... There is content in deep layers that not everyone can understand.

And your first step is to come here and ask... Can anyone tell me how to create my compiler?

Yes, I do think it is a bit ambitious for you in this moment

My concern is which pary i jave to consider here.
I no iys a tricky task.
How tp begin with dis??
Google i nobut to be mor specific what????

Get used to write proper english please. Chat-SMS-Text makes your message looks not serious, on the other hand... not all people are english speakers and may not understand what you say (as I am not understanding right now)

This is easier than with the languages targeting native platform, because you would need to generate machine code. With .NET, there is no machine code. You can parse code and translate it to CodeDOM. Please see:
http://msdn.microsoft.com/en-us/library/y2k85ax6%28v=vs.110%29.aspx[^].

In other words, you can implement this method: http://msdn.microsoft.com/en-us/library/system.codedom.compiler.codedomprovider.parse%28v=vs.110%29.aspx[^]. But you don't have to; you can just populate DOM the way you want and CodeDOM will generated the assembly for you.

Parsing is a separate topic. Well, you can invent your own parser from scratch, learn the parsing techniques, or use some available compiler-compiler. With a compiler-compiler, you would need to formally define the input language; and the compiler components will be generated for you. Please see: http://en.wikipedia.org/wiki/Compiler-compiler[^].

See also this article: http://msdn.microsoft.com/en-us/magazine/cc136756.aspx[^].

This CodeProject article even suggests a Compiler Construction Kit for .NET: Irony - .NET Compiler Construction Kit[^].

Solution 2

Creating your own compiler is not a trivial job: it's a lot of careful design and coding, if you want it to be any use in the real world.

There are a lot of books on compiler design: Google[^] can help you get started.
Some of the stuff there is "Free" - I don't know if that means "stolen" - and some of it is background material, but there should be enough to get you started thinking anyway.

But don't expect this to be a "one weekend" project: a modern compiler is written by a team of people, and can still take years to produce!

Or just go an download Roslyn :)

Btw, agree to what you said +5!

Sergey Alexandrovich Kryukov 13-Apr-14 12:39pm

Roslyn does not help to create a compiler, it just is set of available open-source compilers. Well, one could learn how compiler works, but it's hard to use as a tool for learning how to create your own.

For creation of a compiler, one could use, say, a compiler-compiler. Please see Solution 3.
