Hi
I have one issue coming up
in using Eval.JScriptEvaluate
In
our application we are processing several thousands of item using some rule expression. The rule expression will be looking like (true || true) && (true || false || true), for e.g.
To
process this rule expression we are using JScriptEvaluate.
The code used
in the application goes like this,
public
static object EvalExpression(string Expression)
{
VsaEngine Engine
= VsaEngine.CreateEngine();
return Eval.JScriptEvaluate(Expression, "unsafe", Engine);
}
The problem
with this code is, sometimes it gives the following error. I have pasted the error here with its stack trace.
Index
was outside the bounds of the array.
at Microsoft
.JScript.Stack.Push(Object item)
at Microsoft
.JScript.Eval.DoEvaluate(Object source, VsaEngine engine, Boolean isUnsafe)
We cannot predict
when this error comes. While debugging the error did not show up at all. But in release mode, once in 10 times or so this error comes.
I tried closing the VsaEngine instance
and recreate it again.
But it ended up
with another exception which says, "Microsoft.Vsa.VsaException: EngineClosed (0x80133011)".
Can anyone give
some idea on how to resolve this issue?
Thanks
