Question

//this is testing

value = Evaluator.Evaluate("(((((AAAAA2 + 123)))))", Lookup); //223 expected

//yet it crashes due to the unhandeled extra parenthesis any help would be great, this is the code where it crashes, thanks.

if (")".Equals(token))
{ //closing parens, we need to evaluate inner

//Must contain at least two values on the stack or the closing paren is invalid
//if (valueStack.Count < 2)
//{
// throw new ArgumentException("Invalid formula, not enough values inside the parentheses.");
//}

//get the previous value
int prevValue = valueStack.Pop();
//now get the previous operator
String prevOperator = operatorStack.Pop();
while (!"(".Equals(prevOperator))
{

Explanation / Answer

Run the code till it reaches string length:

If '(' then just continue:

Then when we get some number (operand) push into stack

When we get some operator, Pop two elements from stack, eveluate them and again push into stack.
