How to use/run C# code from TCC via PSHELL

[Joe Caverly]

Using my cs2ps1.btm file,
you can run your C# code from TCC via PShell.

Ref: Write/Run your C# code in a .btm file

In this example,
I have copied the cs2ps1.btm file to test.btm

On the initial run,
you will require the Microsoft C# compiler to be available to create the .NET .dll.

After that,
the .dll will be used instead of being re-compiled.

Example use:

R:\>copy u:\cs2ps1.btm test.btm
U:\cs2ps1.btm => R:\test.btm
     1 file copied

R:\>test.btm

R:\>

After copying cs2ps1.btm to myfile.btm,
add your C# code,
and run myfile.btm to execute your C# code.

Note well the following switches in the code;

useDLL
rebuildDLL

If you make changes to your C# code,
make sure to either set rebuildDLL=Y,
or the better method,
delete the generated .NET .dll before running your modified C# code again.
