how can i write functions in String class without using any tools?
-
how can i make my string to char[] without using any built-in classes or prepared methods, += and = or 'foreach' in C#? in an other expression, i want to (have to) write trim, insert, concat, countOf(char c) and etc without using any of methods or classes or foreach and even += or + in C#. how is that? please help, thanks.
Is there a reason why you are wanting to reinvent the wheel?

Cute. Considering that String IS a class under .NET, that kind of makes the assignment contradictory to itself, now doesn't it?

I don't see how you can do it without =, but a string is an array of chars, and if you use a for loop instead of foreach, you can get each char by index, as in myString[0]

excuse me, but i haven't to use indexes, too.

Then I suspect your teacher is a moron. An index is the only way to get those chars out of the string.

no but it's my homework :) and i have to write that till next two days!

So - are you meant to use telepathy? Your professor has effectively ruled out all useful constructs.
Deja View - the feeling that you've seen this post before.

Yeah, it's homework. I don't have a problem with trying to point him in the right direction, he was up front about it and he's not asking for a solution. It sounds messy tho.

Might be a safe bet. I don't even subject my CS students to worthless crap assignments. Assignments I push on them have some real meaning to them.

I think you need to re-read the assignment. You seem to be saying 'turn a string into a byte array without using any methods on the string class that would give you access to the contents of the string'.

Yeah, they should be learning things they can use, although I am always for students writing a list class that they will never use, for example.

Didn't you mean to direct this to Sajjad? I'm not the one doing the assignment :-\

I usually suggest prayer when people ask stuff like this.

Sure, it primes them up for writing code that never gets used because boss says otherwise, and writing something like a list class teaches the fundamentals of OOP.

Exactly, since they will walk out of the classroom with, hopefully sharper skillsets that can be of value to them. I've had students in the past, who earned lower than average grades thank me for increasing their skillsets, though their academic grade doesn't necessarily reflect it.
