Parsing calculation tree from string

Question

I there any built in library in c# or automatic code generator which recieves configuration file and builds parser of calculaton tree from string if there is no could you please help me with advice Example: "-2+5>3" I would like to build calculation tree where < is root '+' is its right son 3 is left son '-2' is left son of the + and 5 is its right son. And the tree could do evaluation in this case true or false.

Answer 1

Take a look at sprache. It's a simple parser which would allow you to build the expression tree and then evaluating it should be the easy bit.

Answer 2

Have you looked at the System.Linq.Expressions? for example How to convert string into System.Linq.Expressions.Expression in C#?
