Hi,

Try this:

C#

int cityInt = -1;
try
{
     cityInt = Convert.ToInt32(Console.ReadLine());
}
catch
{
     Console.WriteLine("Input isn't an integer!");
}
if (cityInt != -1)
{
      var city = new city(cityInt);
}

Hope this helps.

hey man, I change the way of code and again problem to give value from keyboard:
this is a class:
class Boardi
{
public static int N;

private int[] board;
private int col;
public Boardi()
{
board = new int[N + 1];
city= 1;
}

and a list:
static List<boardi> findSolutions(int city, List<boardi> allSolutions)
{
if (city> Boardi.N)
return allSolutions;

To get input, use this line:
Console.ReadLine();
That returns a string. To convert it to an int, use Convert.ToInt32:


int cityInt = Convert.ToInt32(Console.ReadLine());

Yes I use int.parse the same thing.
but i that second case here is different to input value from keyboard because I have a list as u see.... !!

Thomas Daniels 22-Dec-12 12:27pm

And what's the problem?

h5h6 22-Dec-12 12:34pm

the same to input the character from tastier:
here is the clas
class Boardi
{
public static int N;

private int[] board;
private int col;
public Boardi()
{
board = new int[N + 1];
city= 1;
}
and how to give a number to the parameter N
I tried with object:
Boardi p=new Boardi()
and then p.N to direct to N..... but dont work.......

Thomas Daniels 22-Dec-12 12:36pm

Like this:


Boardi.N = ...

Change ... into your integer.

h5h6 22-Dec-12 12:51pm

int value;
value= Boardi.N;
value= int.Parse(Console.ReadLine());
but dont work
I think in a class Boardi maybe we must do something... because parameter N should take value...

Thomas Daniels 22-Dec-12 12:53pm

No, do this:


Boardi.N = int.Parse(Console.ReadLine());
