Answer 3

Deliberately not a good solution,  this will give you a start and next time write a sample of the code you have written and you will get useful help.

for( int i = 0; i < 6; i++ )

{

      string input = Console.Readline()

      string[] parts = input.split(' ');

      foreach( string value in parts )

     {

            DoSomething(value);

     }

}

Hi,

How do you want to have this data?

Array of array? i mean IList<int[]> ?

 static void Main(string[] args)
        {
            var inputList = new List<int[]>();
            while (true)
            {
                var intArray = new List<int>();
                var value = Console.ReadLine();
                //break with empty line
                if (string.IsNullOrEmpty(value))
                {
                    break;
                }
                int result = default(int);

                foreach (var item in value.Split(' '))
                {
                    if (!int.TryParse(item, out result))
                        Console.WriteLine("Not a valid data");
                    else
                        intArray.Add(result);
                }
                inputList.Add(intArray.ToArray());
            }
        }

Hope this helps you...

Answer 8

I would do this:

var q = File.ReadAllLines(filename).Skip( 1 ).Select( o => o.Split( ' ' ).Select( int.Parse ) );

It's not really robust, but it's easy.

The idea here is that you read all the lines of the file into an array of strings.  Then you skip the first line, because that's just the count.  It's not really necessary to verify that the count is the same as the number of lines that follow.  You can either use the number on the first line as the authoritative count or you can use the data that follows as the authoritative count.  I'm doing the latter.  It's not hard to parse the int on the first line to assert that they are the same, or to skip processing of extra data.  But if we assume your input is well formed, then we can skip that step.

Then each line gets split by the space character into an array of strings.  We parse them all as integers by filtering that array with Select( int.Parse ).  This returns an IEnumerable<IEnumerable<int>>.

To walk it you could do this:

foreach( var line in q ) {
  foreach( var item in line ) {
    Console.WriteLine( item );
  }
}

If you want to index your data then you can .ToList() those queries.

Here's an example:

var data = File.ReadAllLines( filename ).Skip( 1 ).Select( o => o.Split( ' ' ).Select( int.Parse ).ToList() ).ToList();

Console.WriteLine( data[2][1] ); // should be 3

If you put the whole thing in a try-catch block, then you can handle missing files, malformed data, etc.

Answer 9

ahh I understood,

just go on with:

 while(true)

{

string s = Console.ReadLine();

if(s.ToLower() == "exit") break;

Console.WriteLine(s);

}

this allows you whatever input you want to put in :)...

But if you want strict input with an space in the middle containing then..

 while(true)

{

string s = Console.ReadLine();

if(s.ToLower() == "exit") break; // if you write exit, it exit

if(!s.Contains(' ')) continue; // if it does not conatin an space in the middle it reads again the input

if(s.Split(' ').Length < 3 || s.Split(' ').Length > 3) continue; // if there are more than 3 splitet inputs, continue re take input

Console.WriteLine(s); // at the end write this line :@ :)

}

Hope this was what you wanted.. if not reply back

Answer 10

Hi,

here i use regex to get the result:

     Regex rEx = new Regex(@"(?<one>\d{1,2})*(?<two>\d)?");

            string s = null;
            do
            {
                s = Console.ReadLine();

                Match m = rEx.Match(s);
                int? one = null;
                int? two = null;            

                if (m.Groups["one"].Success)
                {
                    one = int.Parse(m.Groups["one"].Value);

                }
                if (m.Groups["two"].Success)
                {
                    two = int.Parse(m.Groups["two"].Value);
                }
            }
            while (!string.IsNullOrEmpty(s));
