convert string to int

How is this possible? Anyone has any idea? the type "string" is different than the char* string in C++.


For example, if I have the string "12", and I want it as an int 12

Because .NET enforces strong typing, converting a string to an int is not a valid conversion operation. I'm not exactly sure there is no way around this, so you many want to play with the System.Convert class. If I was at my computer, I would try for myself..;)

The thing I am trying to do is to read a line of text from a file...

there I use string.substring() to fetch the parameter I need.
Then I need to upload the info to an SQL db into an int field.
The variable is really a week number, so I really don't want to change the db field. It feels very wrong. I won't do any arithmetics, just basic comparisons with boolean operators.



Anyone with suggestion, please shout!!!!


btw
using System.Convert;

won't work... unknown class...

Then you prolly have other problems post your code

The code is a bit large to post on the forum... but I declare my namespaces like standard procedure:

using System.IO;
using System.String;

etc
etc

It seems like intellisense won't recognize the Convert class as member of System??? Anything I have to add???

Anything I can try?


thansk for the answer btw... :)

You need this:

Code:

---

using System;
//.... Rest of your code

---

Solved it

I could just write Convert.whatevermethod();

no namespace declaration was needed.... spoooky :)
