Jscript Solution for Eval

D

Derek Hart

I have read several threads on using Jscript to simulate the Eval function:

using system
Class DynamicCode
{
function runcode(code : string)
}
}

Being a newbie to working between languages, can you tell me how to compile
this into my VB.Net app using Visual Studio.Net. I assume this needs to
become its own DLL. Then Intellisense should work to call this in VB.Net,
right?

I wish to execute code from a string. The string will have a function name,
which will return a string:

Dim a as string
a = "MyFunctionName(param1, param2)"

I have seen a ton of people discuss how reflection does this, but I cannot
find the syntax to do this. I have tried several code example off of
gotdotnet and other articles. Can somebody please show me the code to do
this?

Thank You,
Derek

In the viewpoint of syntax, .NET doesn't support do so. If you wanted to do
this, you might write your code to interpret the content of string and then
call some custom functions or method to do some work.

In other words, you can do it with your application instead of the direct
support from .net.

Reflection is used for class libraries that need to understand a type's
definition in order to provide some rich functionality. Reflection doesn't
do the job as you mentioned...

::Look, this absolutely can be done with reflection. That is a fact.
