I am using IronPython within a C# .NET application.
I have a class that the Python code uses, so I create a scope and set
the variable, then execute the engine like this:
private ScriptEngine scptEngine = null;
private ScriptRuntime scptRuntime = null;
private ScriptScope scptScope;
private ScriptSource scptSource;
public pyEngine()
{
scptEngine = Python.CreateEngine();
scptRuntime = scptEngine.Runtime;
scptScope = scptEngine.CreateScope();
AddAssemblies(scptRuntime);
SOA SOA_screen = new SOA(); // my Class
scptScope.SetVariable("screen", SOA_screen);
scptSource =
scptEngine.CreateScriptSourceFromFile(scriptFile);
scptSource.Execute(scptScope);
}
This runs fine. But within the Python code, if I detect an error, I
want to exit out of scriptFile.
I check a flag and try to exit if flag is false: so, the basic python is:
if MessageScreenIsActive == False :
screen.Say("CAN NOT PROCEED: " + screen.lastResultMessage);
sys.exit()
This throws an exception.
That will throw a SystemExit exception. You can have exception handling
in your C# that catches this specific error.
But this:
if MessageScreenIsActive == False :
screen.Say("CAN NOT PROCEED: " + screen.lastResultMessage);
sys.exit
You're not actually calling sys.exit here...
All the best,
Michael
only exits the <IF block> -- not the whole script.
Of course, I can bracket off all of my code with if/else and control
it this way, but there must be a simple way to simple exit the
script... isn't there?
Thanks for reading!
