How to take input !!!!!

CodeMaker · January 4th, 2005, 11:48 AM

Hi,

I am new with C# language. I got the book professional C# of wrox. I have read the 1st 6 or 7 chapters of this book and I found the book a good one but surprisingly now I find myself with a situation that I still don't know one thing and that is- in console mode how to take input from the keyboard. In these 7 chapters, there was not a single line about taking input values from the keyboard.

I know about Console.ReadLine() but how to take input in 2 integer variables, I mean what is the scanf or cin equivalent of C#, plz help.

Goodluck and Goodbye...

I think the way you get the same functionality as scanf is to use ReadLine and then use regular expressions to parse the information returned.

Or you could just use

Code:

int value1;
int value2;

Console.WriteLine("Enter value 1: ");
value1 = Convert.ToInt32(Console.ReadLine());
Console.WriteLine("Enter value 2: ");
value2 = Convert.ToInt32(Console.ReadLine());

Thanks a lot for the reply, but what I actually need is to take few values that is in a single line

like this:

24 99 1002 33

i should have used: scanf("%d%d%d%d",&x,&y,&z,&p);

if I use ReadLine, then will it not destroy the whole line for just one value input.

I am trying to make a programme that can evaluate the value of an arithematic expression, so I need to take many values from a single line.

can you help me in this....thanks again.

Goodluck and Goodbye...

The ReadLine method returns a string so it is entirely possible to return your values...

24 99 1002 33

But you will have to split them up yourself using string.Split or regular expressions.

thanks a lot, i think i can handle it from here, but i would have been happier if i had something like scanf which can automatically take those values from the stream, ok i will read about regular expressions and string.Split, thanks a lot...

Goodluck and Goodbye...
