Is EVAL type functionality Available in VB.NET?

Question

I would like to pass in a few paramweters into a function and parse out an executable if statement without using a Case statement for each possibility.

For instance I would like to pass ">=" into a function and then string it into an if statement without doing this

Case OperatorParameter

Case ">="

if xxx >= yyy

etc..

Can this be done??

Thanks for any help

There's no Eval functionality built into the VB.Net language or the .NET framework themselves. However if you add a reference to the Microsoft Script Control to your project then you can use the Eval() function in VBScript. Here's a quick example: Module Module1 Dim sc As New MSScriptControl.ScriptControl() Sub Main() sc.Language = VBScript Dim result1 As Boolean = Test( >=  4.0 2.0) Dim result2 As Boolean = Test( >=  2.0 4.0) Console.WriteLine(result1) Console.WriteLine(result2) Console.ReadLine() End Sub Public Function Test( ByVal op As String  ByVal operand1 As Double  ByVal operand2 As Double ) As Boolean Return sc.Eval(operand1.ToString() & op & operand2.ToString()) End Function End Module
