Compiling C# for use into a VB application

Question

Is there any way that I can compile a piece of C# code written on a file, then insert it in a function and run it(under VB.net)?

http://www.codeproject.com/Articles/1931/C-Compiler (is this any good?)

Answer 1

If you really MUST, you can compile the c# code into a DLL file, then you can make a reference to that DLL file and import it into your class....

Any particular reason you can't save yourself the trouble and just use one language(either c# or vb)? 

There's plenty of free c# to vb translators out there... and the translation process is relatively painless....

Here's an example of one such site:

I am making a kind of debugger that goes line by line (of a user written code in C#) and displays current memory objects.

I once found a project that compiled a piece of code (user written) in VB and used it in a function but that was a long time ago and i can't find it anymore. :(

Answer 3

You intend to use a code written in c#, with a vb project? if so....

It is very easy, you can create a new class library in c#, add your code(remembering that public things will be accessible from outside of your library).

You the build your solution, and in the output of your debug>bin folder will  be a  copy of your dll file.

If your VB project you go to the solution explorer window, and click "Add reference", navigating to the dll that is in the debug>bin folder of your c# class library project.

Now that you have added a reference, you import it..

Or do you simply need to evaluate the TEXT of a c# code?

in which case, you could simply open the file to a string

Looks like there is a misunderstanding.

Let’s say that I have a Form that contains a textbox.

A user inputs this code into the textbox

Int a=1,i;

for(i=0;i<10;i++)a=a*10;

I need to compile the code that is in the textbox and use it in a function(run it inside a function in my application).

Can I do that?

Answer 5

No there is no C# scripting tool, because that is what you are asking.

Of course you can build a program using csc.exe

http://msdn.microsoft.com/en-us/library/78f4aasd.aspx

But that is not simply doing it scripting and needs more than just only the code you show.

The code can however not been used then in a VB build (assembly) be aware that it is the same for VB scripting or whatever kind of scripting..

That sounds like a job for codedom:

Heres a couple examples I found with a quick internet search:

http://www.codeproject.com/Articles/1931/C-Compiler (Compile C# in c#)

http://www.codeproject.com/Articles/5472/Compiling-NET-code-on-the-fly (Compile Vb in Vb)

You can easily twist either of these examples to compile either language as well, plus you can use a c#->Vb convertor or vb->C# converter to translate the code between languages.

Answer 7

There is no "scripting" period. The code is SOURCE code.

Yes, the second link is the project that I could not remember of, thank you a lot!
