I need to test a logical expression held in a string to see if it evaluate to TRUE or FALSE.(the strig is built dynamically)  

For example the resulting string may contain "'dog'<'cat' OR (1>4 AND 4<6)". There are no variables in the string, it will logically evaluate. It will only contain simple operators = > < >< >= <= and AND , OR and Open and Close Brackets, string constants and numbers. (converted to correct syntax && || etc.)

I currently acheive this by creating a jscipt function and compiling it into a .dll. I then reference the .dll in my VB.NET project.

```
class ExpressionEvaluator  
{  
  function Evaluate(Expression : String)  
  {  
    return eval(Expression);  
  }  
 }  

```

Is there a simpler method using built in .NET functions or Lamdba expressions.
