Convert a numeric expression which is stored as string into integer in C#

11 New Member
Hi,

I'm having a numeric expression say

"((2*3)-(3*4+5))" returned from a method as a string value... now i have to evaluate the expression and store it in an integer vaariable.

Convert.toint or int.parse is not working and since i'm new to .net development i have no idea of how else to convert this.Please do help me regarding this

you will need to parse the string into your own set of grammer and perform the mathmatical operations yourself.

Not unless you can find a way to import a function from some other language that does it?

Interesting. I see I have been working too long with interpretive scripting languages (like Perl and PHP). Its easy to forget that something like an "eval" function doesn't exist in a compiled software language.

If you do decide to go all the way with this then check out Jos' compiler series in the Java howTos section.

Nice link to lots of good info! Thanks! No, I am coming from compiled languages, so I am not a newby here (Fortran submitted as batch jobs using punch cards back in 1972 was my first, what a pain!) but it is easy to get used to some of what interpreted languages offer :):):)

Hi All: I know I am missing something easy but I can't find the problem! I have a program which reads an integer as input. The output of the program should be the sum of all the digits in the integer that was entered. So, if 353 was entered, the output should be 11.

Hello folks, I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>". The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed. This is as boiled down as I can make it. Here is my compilation command: g++-12 -std=c++20 -Wnarrowing bit_field.cpp Here is the code in...
