native .NET equivalent of Microsoft Script Control ?

[Mad Scientist Jr]

Is there a native .NET equivalent of the Microsoft Script Control,
particularly the Eval method? See here:

http://www.devx.com/vb2themax/Tip/18773

It works great - it even compares string expressions. I just would
prefer a native .NET version over COM if at all possible.

Sample code:

Dim scriptControl1 As New MSScriptControl.ScriptControl
Dim sExp As String
scriptControl1.Language = "VBScript"
Textbox1.Text = ""
sExp = "12 + 3 * 10"
Textbox1.Text += sExp & " = " & scriptControl1.Eval(sExp) & vbCrLf
sExp = "(`abba` < `bagel`)"
sExp = Replace(sExp, "`", Chr(34))
Textbox1.Text += sExp & " = " & scriptControl1.Eval(sExp) & vbCrLf
sExp = "(`red` < `bagel`)"
sExp = Replace(sExp, "`", Chr(34))
Textbox1.Text += sExp & " = " & scriptControl1.Eval(sExp) & vbCrLf
sExp = "((1*5)*5)"
sExp = Replace(sExp, "`", Chr(34))
Textbox1.Text += sExp & " = " & scriptControl1.Eval(sExp) & vbCrLf
sExp = "( (`abba` < `bagel`) and true) or ( ((1*5)*5) = 25 ) "
sExp = Replace(sExp, "`", Chr(34))
Textbox1.Text += sExp & " = " & scriptControl1.Eval(sExp) & vbCrLf

There isn't a native equivalent but you can do the same thing with CODEDOM
API.
See how on http://www.odetocode.com/Code/80.aspx

Not really, you can use Reflection to compile your own module at runtime but
this is a very method for simple interpreting simple expression. For other
solutions, take a look at:

JScript.NET?

There's this:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnclinic/html/scripting06112001.asp

but I seem to recall that those scripting engines were not supported or were
deprecated in the 1.1 framework, or similar language that I can't remember
the details of.

Is it true that VSA is obsolete?
If so, what replaces it for scripting support in .NET?

Hello,


You can use VSA technology to have native support for VB.NET and
JScript.NET
in .NET applications.
have a look to the following urls:
